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

Paul Graham advised us that it's better to have 100 customers who love your product than a million who just like it, emphasizing the importance of passionate advocates.

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.

It's easier for startups to begin with a product that a small number of users love and then expand from there, rather than trying to please a large audience from the start.

It's important to evaluate startups based on whether they have a small number of users who truly love the product, rather than just a large user base.

Instead of finding a ton of people who like your product, focus on finding 10 to 20 customers who truly love it, as growth comes from great products, not the other way around.

The mantra at Y Combinator is to 'make something people want,' which is essential for solving most startup problems.

I often advise startups that it's better to seek deep appeal and create something that a few people love, even if most people don't get it right away.

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.
