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

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.

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.

Focus on quality over quantity in your product features. Users prefer great products rather than just a multitude of features.

Paul Graham advised us to focus on a few users who truly love our product rather than trying to appeal to a larger audience, emphasizing the importance of building strong relationships with early adopters.

When starting something new, especially in an established category like email, it's crucial to focus on a specific user base rather than trying to please everyone. I believe that creating a product with deep appeal to a small group of people is more effective than trying to attract a broad audience from the start.

At Y Combinator, we advise founders to focus on creating a product that 100 people love rather than something that 1 million people merely like, as those 100 passionate users can become your viral sales force.

Founders should focus on building a better product rather than worrying excessively about competitors; delivering more value to users is key.
