What is *Lean Impact* by Ann Mei Chang about?

*Lean Impact* applies Silicon Valley's lean startup methodology to social innovation, offering strategies to maximize scalable, ethical solutions for global challenges. Ann Mei Chang combines rapid iteration, community involvement, and audacious goal-setting to help nonprofits and social enterprises achieve transformative change. Key themes include balancing ethical testing with vulnerable populations and prioritizing local input over top-down solutions.

Who should read *Lean Impact*?

This book is essential for social entrepreneurs, nonprofit leaders, and policymakers seeking data-driven frameworks to amplify impact. It’s equally valuable for tech professionals transitioning to social sectors, offering practical tools like Minimum Viable Products (MVPs) adapted for ethical constraints.

Is *Lean Impact* worth reading?

Yes—it bridges Silicon Valley efficiency and social sector missions with actionable insights. Chang’s case studies (e.g., solar lighting initiatives, orangutan conservation) demonstrate how lean principles accelerate impact while reducing risks. Critics praise its focus on humility and iterative learning over rigid planning.

What are the three core principles of *Lean Impact*?

1. **Think Big**: Set audacious goals for systemic change. 2. **Start Small**: Test hypotheses through low-cost, rapid experiments. 3. **Seek Impact Relentlessly**: Continuously refine based on data and feedback. These principles prioritize agility while addressing complex social challenges.

How does *Lean Impact* differ from *The Lean Startup*?

While both emphasize rapid iteration, *Lean Impact* adds ethical guardrails for working with vulnerable communities. It shifts focus from profit to scalable social benefit and stresses participatory design with affected populations, avoiding top-down "savior complex" pitfalls.

What are common critiques of *Lean Impact*?

Some argue its Silicon Valley-inspired methods risk oversimplifying systemic issues or underestimating cultural barriers. Testing MVPs in high-stakes contexts (e.g., healthcare) also raises ethical concerns about trial-and-error approaches with marginalized groups.

How does Ann Mei Chang recommend involving communities in social innovation?

Chang advocates co-designing solutions with those directly affected by problems. Examples include partnering with local leaders to refine clean water projects and using feedback loops to adapt education programs. This reduces bias and increases sustainable adoption.

What is a "Minimum Viable Product" (MVP) in *Lean Impact*?

An MVP in social innovation is a simplified prototype (e.g., a pilot program serving 50 beneficiaries) to test core assumptions quickly. Unlike tech MVPs, it requires stricter ethical reviews and closer monitoring to avoid harming participants.

Revolutionizing Social Impact: When Silicon Valley Meets Global Change

The year was 2012, and the Ugandan government had just done something unthinkable - they issued a moratorium on mobile health projects. After being inundated with hundreds of well-intentioned but disconnected pilot programs that failed to scale or integrate with existing systems, they'd had enough. This watershed moment perfectly captures the crisis Ann Mei Chang addresses in "Lean Impact" - a book that has become required reading in social entrepreneurship programs at Stanford, Harvard, and beyond. As a former Google executive who transitioned to become USAID's first Chief Innovation Officer, Chang brings a unique perspective that has made this work a favorite among tech philanthropists like Melinda Gates and Pierre Omidyar, who call it "essential reading for anyone serious about solving problems at scale." Drawing from interviews with over 200 organizations worldwide, Chang reveals how the innovation principles that transformed Silicon Valley can revolutionize social good - not by imposing tech solutions on complex problems, but by fundamentally changing how we approach social change itself. The book arrives at a critical moment when traditional approaches are proving insufficient to address accelerating global challenges, from climate change to inequality. Its cultural impact extends beyond the social sector, influencing how corporations like Unilever and Patagonia approach their sustainability initiatives and how government agencies redesign their innovation programs.

Chapitre 2

Think Big: Setting Audacious Goals for Transformative Impact

When Ben Mangan looked at his organization's impact after ten years of operation, he faced a sobering reality. EARN had helped just 7,000 low-income Americans build savings - barely scratching the surface of the 50-70 million Americans needing financial security. This realization led to a pivotal decision: announcing a goal to help a million people save a billion dollars by 2022. This required abandoning their in-person, dollar-matching model for a technology platform supporting self-service. The results were staggering - in their first year with the new approach, they reached 85,000 users, ten times more than their previous 15 years combined. This exemplifies the first principle of Lean Impact: think big. The social sector paradoxically combines audacity in tackling entrenched problems with timidity in setting goals that match the actual scale of need. We become so focused on what seems achievable within current constraints that we lose sight of the true problem magnitude, essentially "emptying the ocean with a spoon." Tech startups aspire to "hockey stick growth" - where audience growth shifts from slow and linear to surging and exponential. Yet we rarely see such projections in social impact work. Most social organizations operate on linear growth models where each dollar buys exactly one dollar of value, with little room for research or experimentation that might create disruptive solutions. Scaling social solutions requires shifting from linear service delivery to exponential transformation, starting with audacious goals based on the size of the need rather than anticipated progress. There's often a mismatch between strategy and problem nature in social work. We create many "dry cleaners" (ventures with well-understood needs, solutions, and models) while tackling problems with Amazon-level uncertainty and scale. When solutions are unclear and needs vastly underserved, we must take greater risks, set higher ambitions, and test multiple alternatives. Your goal must be clearly articulated so everyone can work in the same direction. Social impact combines breadth and depth - how far we reach and how much we improve the status quo. As Astro Teller points out, a 10-fold improvement can sometimes be easier than a 10% one, as incremental improvements are often already exhausted. Well-defined goals should answer how many, to what extent, and by when. myAgro exemplifies this with their aim to "increase the income of a million smallholder farmers by $1.50 per day by 2025." We often conflate our ends and means in mission-driven work, becoming so immersed in our interventions that we lose sight of our ultimate goals. Keeping your North Star goal in focus helps determine if you're moving the needle appreciably or need to pivot.

Love the Problem, Not Your Solution: The Power of Proximity

When Proximity Designs decided to work with smallholder farmers in Myanmar, cofounders Jim Taylor and Debbie Aung Din didn't just conduct market research - they moved there. This proximity allowed them to design affordable irrigation solutions with direct farmer input and rapid feedback. By treating people as customers rather than recipients, they preserved dignity and created accountability. Nine years later, Proximity became Myanmar's largest social enterprise, reaching 80% of farmers and increasing incomes by an average of $250 annually. Good solutions rarely emerge from fancy offices far removed from the problem. The best social entrepreneurs deeply understand their customers' lives, challenges, and desires. Proximity Designs now spends six weeks doing deep dives, setting up pop-up studios in communities where teams can be immersed in local experiences. Even when working with nearby populations, proximity matters - when addressing social isolation of adults with cognitive disabilities in Canada, Dr. Sarah Schulman's team moved into public housing to live alongside their customers. Problems rarely exist in isolation but are influenced by policies, market dynamics, and stakeholders. Systems thinking - analyzing complex interrelationships within a problem - has become essential for creating lasting change. Little Kids Rock demonstrates this approach: founder David Wish transformed music education by working with universities to train teachers and with government to include "modern band" in curricula rather than focusing on individual educators. Today, their program operates in over 2,400 schools across 45 states. After gathering insights through research and system mapping, distill your target audience into specific customer segments that share experiences and challenges. Avoid over-generalizing entire organizations or communities. Select a primary customer segment as your initial focus - the people who will benefit most from your solution and become early adopters. Facebook exemplifies this approach, starting exclusively with Harvard students before gradually expanding. Social sector innovation faces a unique challenge: satisfying two different customers - beneficiaries and funders. Unlike businesses where customers both benefit from and pay for products, social enterprises must navigate funders' expectations for detailed plans while maintaining flexibility to adapt. Grants typically require meticulous planning upfront, creating a waterfall model that impedes lean innovation. Balancing these competing demands is essential for successful social innovation. Kinari Webb's work protecting orangutans in Indonesian Borneo demonstrates "radical listening" - understanding community needs before proposing solutions. She discovered deforestation occurred when families needed quick money for medical emergencies, leading her to establish Health In Harmony, a local clinic that reduced logging households by 89%. Falling in love with the problem means pursuing the root cause wherever it leads and continuously validating your understanding as conditions evolve.

Finding the Right Solution: Beyond Brainstorming

Innovation isn't just about brainstorming sessions with colorful Post-its. While ideation can be exciting, we should consider that good solutions might already exist. Google didn't invent web search and Facebook didn't invent social networking-they improved existing concepts. Rather than becoming wed to one solution, we should treat each as an option to test against real-world data. Effective ideation draws from design thinking principles, encouraging divergent thinking where all ideas-even outlandish ones-are welcomed with a "Yes, and..." approach. Diverse participation is crucial: community representatives provide lived experience, stakeholders offer expertise on existing structures, and specialists from different domains introduce fresh perspectives. USAID's Grand Challenge during the Ebola outbreak exemplifies this approach-bringing together everyone from freshmen to wedding dress makers resulted in a revolutionary protective suit design that could be removed safely in five minutes rather than 30. Despite our attraction to creating something new, building on existing proven solutions often offers lower risk and higher reward. The YMCA's successful adaptation of an NIH diabetes prevention study demonstrates this principle-they modified an academically proven intervention into a cost-effective, group-based format that eventually became a Medicare-covered benefit. Evidence Action exemplifies an organization that systematically transforms academic research into scalable programs, as seen with their "No Lean Season" initiative that provides transportation stipends to farmers during non-harvest periods. As stewards of resources-whether investors' capital or donors' contributions-we have an obligation to maximize social benefit. Yet organizational priorities often lead to suboptimal outcomes: nonprofits rarely merge despite potential efficiencies, teams reinvent solutions that already exist, and competition for grants discourages collaboration. Personal satisfaction sometimes trumps impact, as illustrated by the author's friend who runs a small artisan business rather than connecting craftswomen to established distribution networks that could help more people. Innovation doesn't end with ideation-it's only the beginning of a journey that requires multiple iterations. Teams naturally become attached to their solutions, but the messy reality rarely matches theoretical expectations. Like scientists testing a promising drug in clinical trials, we must follow the evidence rather than our attachments. Expect to return to the drawing board repeatedly, relentlessly seeking impact through continuous refinement and learning.

The Lean Startup Methodology for Social Good

Having developed a potential solution, we now face the "99% perspiration" phase-turning concepts into results through experimentation and learning. The Lean Startup process applies scientific method rigor to systematically test risk factors that might cause failure, focusing on five key building blocks: identifying assumptions, building minimum viable products, using validated learning, implementing build-measure-learn cycles, and making pivot-or-persevere decisions. Harambee Youth Employment Accelerator in South Africa exemplifies these principles in action. Addressing the crisis of 40% youth unemployment, CEO Maryana Iskander embraced experimentation with measurable targets from the beginning. After discovering that youth lacked both job networks and soft skills while employers suffered from high attrition, Harambee pivoted from traditional academic assessments to measuring learning potential and aptitude. This data-driven approach allowed them to select candidates with personality traits and ability to learn, then train them to fill knowledge gaps. Through continuous experimentation and iteration, Harambee has helped over 50,000 youth find their first jobs. Mission-driven organizations operate under extreme uncertainty in contexts where markets and governments have failed. Success requires systematically addressing risks by identifying key assumptions that could make or break a solution. Beyond the value and growth hypotheses identified in The Lean Startup, social innovation requires a third critical hypothesis: impact. A successful social innovation must deliver value to customers so they'll embrace it, include an engine for growth to achieve scale, and ultimately produce meaningful social impact. After identifying assumptions, the next step is formulating precise, testable hypotheses with measurable outcomes. An MVP is the cheapest, quickest prototype that enables learning through controlled experiments. Despite powerful forces in the social sector that push against starting small, MVPs reduce risk by uncovering issues before widespread deployment. When testing hypotheses, observing actual behavior is far more revealing than asking hypothetical questions. Validated learning uses hard data to confirm hypotheses, cutting through emotion and politics that often drive decision-making. Before deploying any MVP, document key hypotheses, data collection methods, and measurable success metrics to prevent confirmation bias and provide clear criteria for further investment. There's a crucial distinction between vanity metrics (cumulative or gross numbers) and innovation metrics that measure value, growth, or impact at the unit level. The build-measure-learn feedback loop forms the core of the Lean Startup model. The most critical indicator of successful innovation is the speed of iteration-the faster we run through the entire cycle, the faster we learn and improve. Traditional grants with midline and endline evaluations aren't designed to support this model, as meaningful insights may emerge too late to make changes. After several build-measure-learn cycles, you must step back and decide whether to claim success, continue, or pivot. Success means meeting your targets for conversion rate, referrals, behavior change, or cost structure. If you're making progress but haven't reached targets, persevere-but avoid wishful thinking. A pivot changes strategy while maintaining vision. TOMS Shoes demonstrated this when research showed their One for One model wasn't reducing poverty-they pivoted to manufacturing shoes locally and diversifying their giving to include eyeglasses, clean water, and birth attendant training.

Chapitre 6

Start Small, Iterate Fast: The Power of Validation

Validation works best when starting small, allowing faster iteration and improvement. Early learning saves time and money by avoiding unnecessary investments and minimizing unintended consequences with vulnerable populations. Unlike traditional social sector programs planned meticulously and deployed at scale, Lean Impact replaces linear processes with iterative ones based on the scientific method. Despite reducing global poverty by half over 30 years, extreme poverty remains concentrated in Africa, home to half the world's poor, mostly in rural agricultural areas. In 2006, MBA graduates Andrew Youn and Matt Forti founded One Acre Fund to address this gap by offering African farmers a complete bundle of services including improved seeds, fertilizer, training, and market access. After a costly failure with passion fruit cultivation in 2008, where desk research didn't match field realities, Andrew implemented a staged innovation framework. Now One Acre sources ideas internally, evaluates them on multiple criteria, and tests progressively-first with prototypes, then small farmer groups, and finally district-wide trials. This R&D approach, funded at an unusual 7% of their budget, has generated a 4-6x return on investment by allowing them to fail small and iterate quickly before scaling proven solutions. Despite the common sense of starting small and validating before scaling, mission-driven organizations face unique pressures to grow prematurely. The urgency of addressing suffering or averting calamity creates a natural inclination to help as many people as possible, even with unproven solutions. External pressures also drive premature scaling, as funders demand impressive numbers and websites showcase vanity metrics about people reached rather than actual effectiveness. Unlike businesses where success signals are straightforward, mission-oriented organizations must fulfill three sometimes conflicting pillars: value, growth, and impact. Value comes first-if beneficiaries don't use or recommend your solution, it can't succeed. Growth engines must be considered early, as injecting new growth strategies later may force complete redesign. Impact remains the ultimate goal but often takes years to prove conclusively. Without all three pillars, interventions fail: without value, solutions like polio vaccines face resistance; without growth paths, effective programs reach only a fraction of those in need; without impact, interventions can scale massively before evaluations reveal limited benefits. To determine which assumptions to test first, consider risk, time, and cost. The goal is eliminating the greatest risks with minimal investment. Start by identifying "killer assumptions"-the make-or-break risks for your solution-and listen to both internal and external skeptics. Break these assumptions into testable hypotheses, then design simple MVPs to validate them. The key to successful validation isn't perfect experiment design but speed of execution. Each feedback cycle begins with an assumption, formulates a hypothesis, builds an MVP, runs experiments, and learns from results. While online services like Google and Facebook can deploy hundreds of A/B tests daily, social innovations require more manual effort but follow the same principles. Rigorous data collection is a primary driver of impact. While technology solutions aren't always appropriate for development challenges, digital data collection consistently proves transformative. Organizations like Living Goods have revolutionized their work by adopting digital-first approaches-moving "data at light speed versus bicycle speed." Their $2000 Android app prototype helped health workers increase pregnancy identification rates from 35% to 85%.

Creating Value: Solutions People Actually Want

For social innovations to succeed, they must provide something beneficiaries genuinely want-not just what we believe is good for them. Too often, well-meaning investments go unused because they don't address real needs or desires. Unlike businesses where lack of sales provides immediate feedback, free social services lack this critical signal, allowing ineffective interventions to persist. Our goal should be creating solutions that users not only accept but actively demand and recommend to others. After the 2016 US presidential election, former congressional staffers Ezra Levin and Leah Greenberg created a simple 23-page Google Doc advocacy guide as a therapeutic exercise. When shared online, it immediately went viral, crashing repeatedly as millions viewed it. This unintentional MVP revealed an enormous unmet need among people seeking ways to resist the Trump administration. The guide spawned Indivisible, which grew into a movement with over 5,000 local groups that became a major force in progressive activism. Collaborating directly with users throughout the design process leads to solutions that are more readily adopted. Human-centered design (HCD) sits at the intersection of empathy and creativity, making it a close cousin to Lean Impact with its focus on customer-centric rapid prototyping. New Story, a nonprofit homebuilder, discovered "ghost towns" where millions were wasted on unused homes because they didn't meet families' needs. By using participatory design-like having families arrange paper cutouts of buildings-they created communities that addressed real concerns, such as security from gang recruitment in El Salvador. The most effective solutions often come from users designing for their own communities. Claire Reid created Reel Gardening in South Africa at age 16 after struggling to plant vegetables efficiently. Her Garden in a Box encased seeds with fertilizer in paper strips, saving 80% of water needed for germination. Similarly, Sanga Moses, who grew up without shoes in Uganda, quit his bank job after seeing his sister miss school to collect firewood. He developed Eco-Fuel Africa, turning agricultural waste into fuel briquettes that burn longer, produce less pollution, and cost 50% less than wood. Behavioral science can maximize customer value by building on research into human motivations and behavior. The Behavioural Insights Team (BIT), originally established by the UK government, encourages behaviors by making them easy, attractive, social, and timely. In Australia, BIT reduced unhealthy drink consumption by 10% simply by moving "red" sugary drinks to less prominent locations and increasing their price by 20%. The most effective way to validate customer value is putting potential solutions directly in users' hands. CareMessage's Cecilia Corral developed an SMS-based health management system for underserved diabetic patients by testing messages first with family, then with patients at St. Anthony's free clinic. She discovered patients needed simple, gradual information delivery following diagnosis, eventually reaching over two million patients with demonstrated improvements in appointment attendance and health outcomes. Successfully delivering value means engaging all stakeholders in the ecosystem, not just end users. Civilla demonstrated this when tackling Michigan's daunting 42-page public benefits application. After extensive research with residents and caseworkers, they created an immersive simulation that forced state leadership to experience the arduous process firsthand. This visceral demonstration helped secure a partnership with the Michigan Department of Health and Human Services to develop a new application with 80% fewer questions that still met all regulations.

Growth Engines: Scaling Beyond Charity

Despite two decades of slow progress in expanding access to essential services like clean water, electricity, and sanitation (growing less than 1% annually), mobile phone adoption has skyrocketed globally, following the classic hockey stick growth curve. By 2015, over 700 million people still lacked clean water, one billion lacked reliable power, and two billion lacked proper sanitation, while mobile phones had reached even the most remote communities. Today, more households worldwide have access to mobile phones than toilets. This stark contrast demonstrates that massive scale is possible even in challenging contexts when people clearly see value and there's a market-driven business model. The history of mobile health (mHealth) pilots in Uganda demonstrates what happens when growth is an afterthought. Despite hundreds of mHealth pilots across Africa and Asia targeting different diseases with various technologies, few ever reached scale. Organizations ran isolated pilots, duplicating efforts and creating systems that didn't communicate with each other or integrate with government systems. In 2012, Uganda's government issued a shocking moratorium on further mHealth projects after becoming inundated with dozens of overlapping, duplicative programs that addressed niche problems without viable paths to scale. While mission-driven programs typically start with charitable funding, grants alone rarely provide sufficient resources to meet the full scope of needs. The path to scale usually requires shifting from donor dependence to larger, more sustainable financing streams. In developing countries, foreign aid ($147 billion) and philanthropy ($64 billion) are dwarfed by remittances ($224 billion), foreign investment ($513 billion), and especially local government spending ($3 trillion) and domestic company investment ($3.7 trillion). At less than 3% of aggregate financing in developing countries, foreign aid and philanthropy are clearly insufficient to solve problems at scale. Moving beyond donor funding requires shifting from a linear "brute-force" expansion model to one with an engine that accelerates adoption over time. Kevin Starr of Mulago Foundation frames this through two questions: Who is the doer at scale (you, lots of nonprofits, lots of businesses, or government), and who is the payer at scale (customers, government taxation, private philanthropy, or foreign aid)? Growth hypotheses must validate whether the doer can and will do, and whether the payer can and will pay. Off Grid Electric exemplifies a successful market-driven growth model, progressing from USAID grants to test its business model (where families make small monthly payments via mobile money for solar power) to raising over $150 million in private debt and equity. Cross-subsidization allows profits from one product or customer segment to offset costs for another, typically lower-income populations. Aravind Eye Hospitals in India exemplifies this approach, having patients self-select payment options based on accommodation preferences while receiving identical high-quality care. In Liberia, where less than 40% of school-age children attend primary school and half the youth are illiterate, the Partnership Schools for Liberia (PSL) program awarded contracts to eight organizations to operate public schools. The government pays teachers' salaries plus $50 per student annually to operators. First-year evaluations showed students in partnership schools learned 60% more than in government schools. For basic public services like education and healthcare, tapping into government funding streams often offers the most promising path to scale. During field visits across developing countries, Chang consistently observed the challenge of last-mile distribution. Poor infrastructure, low literacy, and scattered populations make reliable distribution particularly difficult in remote rural areas. Organizations typically create their own distribution networks, resulting in fragmentation-separate agents selling mobile airtime, solar systems, cookstoves, healthcare products and more, all in the same location. Organizations can achieve their goals faster by investing in shared infrastructure and collaborating across initiatives.

Validating Impact: Does It Actually Work?

Microcredit's story represents both massive scale achievement and sobering reality check. Despite expanding to serve over a hundred million borrowers worldwide and earning Muhammad Yunus a Nobel Peace Prize, rigorous evaluations decades later revealed it didn't actually reduce poverty as claimed. This illustrates why testing our impact hypothesis-not just value and growth-is essential before scaling social innovations. Despite billions spent on foreign aid over 70 years, academic analysis of 97 econometric studies concluded "aid has not been effective." While social impact is our ultimate aim, it's often practical to test value and growth hypotheses first. But before expanding, we must answer the fundamental question: Does it work? For most social change efforts, the honest answer is usually "we're not sure." GiveDirectly's unconditional cash transfers serve as a benchmark-if a complex program can't deliver more benefit than simply giving cash, is it worth doing? A theory of change maps the causal linkages between activities and their anticipated effects leading to desired results. In its simplest form, it describes five stages: inputs (resources required), activities (actions deploying those inputs), outputs (immediate quantifiable results), outcomes (changes in well-being or behavior), and impact (long-term consequences). While articulating theories of change has become commonplace in program design, they're often never fully validated, with reporting focusing on easily measured outputs rather than confirming intended outcomes or impacts. To minimize risk while validating impact, break down each stage of your theory of change into testable assumptions. For distributing bed nets to reduce malaria deaths, you might test whether people properly hang nets and sleep under them before measuring disease reduction. These usage experiments can be run quickly, allowing you to optimize adoption rates before waiting years to detect changes in disease burden. To design an MVP for impact, start by identifying the riskiest link in your theory of change and test that causal relationship first. When outcomes will take time to manifest, break them down into substeps that can be validated earlier. Your goal is to reduce the greatest risk relative to validation cost. For social impacts that may take years or generations to realize, early indicators can decrease risk and increase likelihood of good outcomes. Summit Public Schools couldn't wait a decade to confirm if 100% of students would graduate college, so they partnered with Facebook engineers to create a technology platform capturing ongoing student data. BRAC, rated the world's top NGO for innovation, impact and sustainability, stands out for its headquarters in Bangladesh, persistent presence throughout the country, cross-sectoral approach to poverty, and commercial enterprises that self-fund 80% of its activities. When tackling diarrheal mortality in 1979 (which killed 252 of every 1000 children under five), BRAC took an innovative approach to oral rehydration therapy. Rather than relying on medical personnel and clinics that couldn't reach rural areas, Sir Fazle decided to teach mothers to prepare the solution themselves, despite opposition from the World Health Organization. Through a series of pilots with rapid feedback loops, BRAC tested and improved their formulation instructions, helping reduce child mortality from 252 to fewer than 50 per 1000. When applying lean approaches in social contexts, many worry about experimenting with vulnerable people's lives. The Silicon Valley mantra to "Move fast and break things" requires careful reconsideration when human beings are involved. Yet experimenting is essential for learning and improvement-the greater risk may be rolling out untested interventions widely or continuing to deliver outdated solutions. Starting small allows for vigilant monitoring of unintended consequences in complex ecosystems.

Chapitre 10

Transforming Systems for Greater Impact

Individual organizations often hit walls of policy and market failures when trying to solve major social challenges at scale. Innovation remains essential, as social entrepreneurs can demonstrate impact and viability of new approaches, de-risking them for government and business adoption. The Skoll Foundation has shifted focus from scaling individual organizations to supporting "systems entrepreneurs" who build coalitions and influence policy to create systemic change. Jordan Kassalow founded VisionSpring to address the 2.5 billion people needing eyeglasses worldwide. Despite selling millions of glasses, VisionSpring realized even ambitious targets would barely dent global need. This led Jordan and colleague Liz Smith to establish EYElliance, bringing together government, industry and nonprofits to address systemic barriers to eyeglass access through school programs, encouraging optical businesses to serve lower-income markets, and integrating vision care into health systems. Many global problems require multi-sector collaboration rather than single-organization solutions. At the US State Department, Ann Mei Chang discovered that while internet coverage existed in many areas, affordability prevented adoption. She convened tech companies, telecom providers, governments, and nonprofits to form the Alliance for Affordable Internet (A4AI), which now includes over 80 organizations advocating for policy change. An early win came when Ghana abolished a 20% smartphone import duty, potentially increasing GDP by $370 million over five years. In the social sector, the ultimate success can be making your own work obsolete. Disease eradication efforts exemplify this mission-focused approach, with smallpox elimination being the only complete success so far, while polio and Guinea worm cases have been reduced to dozens annually. Freedom to Marry, founded by Evan Wolfson, successfully achieved its goal when the US Supreme Court affirmed same-sex marriage rights in 2015, then promptly closed its doors. The structure and availability of funding presents the greatest barrier to social innovation. While private sector investors perform due diligence and then give companies latitude to pivot based on what they learn, grants are often micromanaged with detailed activities, deliverables, and spending requirements. Organizations naturally evolve to match their funding sources, making it difficult to innovate even when more flexible funding becomes available. The funder-recipient relationship needs fundamental reimagining, shifting from suspicion and micromanagement to trust and reward. Chuck Slaughter observes that foundations base funding decisions "90% on strategy and 10% on people, whereas venture capitalists consider these more as an even 50-50 split." When teams are empowered toward shared goals rather than predefined plans, the conversation shifts from strict execution to guidance, capacity-building, and collaborative learning. Unrestricted funding (general operating support) enables organizations to balance immediate tactical needs with strategic investments for future impact. It allows for R&D breakthroughs, improved infrastructure, and staff capacity building. The Edna McConnell Clark Foundation shifted from requiring predefined programming to providing flexible capital that supports organizations' own visions and business plans. Similarly, Ford Foundation's BUILD initiative committed $1 billion to five-year unrestricted operating grants after President Darren Walker realized they were "project-supporting nonprofits to death." We're at an extraordinary moment where charitable entities increasingly embrace business approaches while companies recognize their societal responsibilities. Research shows 89% of Americans prefer purchasing from companies associated with good causes, with millennials particularly valuing social responsibility. Despite growing interest in organizations blending profit and purpose, most institutions remain trapped on one side of the historical profit-purpose dichotomy. This creates a "hybrid gap" where high-impact social enterprises struggle to scale while profit-focused businesses that grow quickly often deliver only modest social impact. We share responsibility to fight injustice, alleviate suffering, open opportunity, and nurture our planet. Lean Impact combines Silicon Valley's innovation appetite with scientific rigor and business focus, starting with audacious goals. Radical social change requires working across sectors to address market and policy failures, bridging profit and purpose paradigms with hybrid mechanisms, and acknowledging our own influence through work, purchases, investments, and donations. There's no single path to Lean Impact-what matters is setting high sights, learning rapidly, and maximizing value, growth, and impact. Think big. Start small. Relentlessly seek impact.

Ann Mei Chang, auteure de Lean Impact: How to Innovate for Radically Greater Social Good, est une experte en technologie de renom et une fervente défenseure du développement mondial.

Forte de plus de 20 ans d'expérience à des postes de direction dans la Silicon Valley chez Google, Apple et Intuit, elle s'est tournée vers l'innovation sociale en tant que directrice de l'innovation à l'USAID et chez Mercy Corps, où elle a été pionnière dans l'application des principes du Lean Startup aux défis humanitaires.

Son livre fusionne l'agilité de l'industrie technologique avec les perspectives du secteur social, prônant l'expérimentation centrée sur l'utilisateur et des solutions évolutives face à la pauvreté, aux soins de santé et aux crises environnementales. L'expertise de Chang est renforcée par son rôle actuel de PDG de l'organisation à but non lucratif Candid et sa reconnaissance comme l'une des « 125 femmes d'impact » de Newsweek et l'une des « personnes LGBTQ+ les plus puissantes de la tech » par Business Insider.

Conférencière vedette lors de TEDx, SxSW et de forums de développement mondiaux, elle fonde son travail sur des entretiens avec plus de 200 organisations à travers le monde. Publié par Wiley en 2018, Lean Impact est devenu une lecture essentielle pour les organisations à but non lucratif, les entreprises sociales et les décideurs politiques à la recherche de stratégies fondées sur les données pour un changement systémique.
