Discover Paul Graham’s top advice for Y Combinator: explain what you've learned from users. Learn how to extract truth from user feedback to build a real business.

It’s better to have 100 customers that love you than a million customers that just sort of like you. If you build something that a few thousand people absolutely cannot live without, you have a foundation.








According to Paul Graham, the most effective advice for founders seeking to get into Y Combinator can be summarized in just five words: "Explain what you've learned from users." This simple directive is considered the best advice per word because it demonstrates that a founder is building a business based on real-world needs rather than just pursuing a hobby or a side project.
Extracting the truth from user interactions is a master art form because people often lie to be nice when asked if they like an app. Founders must look past polite feedback to find a deep, burning need. The goal is to identify a problem so significant that a user is willing to use a crappy, unfinished version of a product just to solve it.
Talking to users and learning from them serves as the bridge between a side project and a real company that investors want to fund. While many founders skip this step or get it wrong, those who successfully explain their user insights prove they are solving problems that cannot be ignored. This focus on user research is essential for achieving product-market fit and securing startup funding.
