Building a strong relationship with your first hundred customers can lead to organic growth as they share their passion with others.

Before launching your product, focus on building quickly and optimizing for the next stage of growth, rather than trying to cater to a large user base right away.

During Y Combinator, we focused on building strong relationships with our first 100 customers, doing things that don't scale to ensure they loved our service.

Startups need to build a product that users love, focusing on a few passionate users rather than a large number of indifferent ones.

Your first users should be people you know, like friends and family, to gather initial feedback and refine your product before reaching a broader audience.

It's better to have a small group of passionate users who love your product than a large number who are indifferent. When launching your MVP, it's okay to do things that don't scale to build relationships with initial customers.

Founders should focus on making one customer happy before scaling; this foundational step is critical for long-term success.

I encourage founders to stay in touch with their first 100 users, as it keeps you informed and connected to their needs.

In the early stages of your startup, focus on building the product and talking to users to gain insights that data alone can't provide.
