Finding product-market fit is the single most important thing that your startup does in the first three years, yet it's often underexplored and underexplained.

Product-market fit is crucial; you know you have it when growth is not your biggest problem, and when you pivot, you get another chance to succeed, increasing your odds of achieving product-market fit by taking multiple high-quality shots at it.

Making a startup work is a miracle, and achieving product-market fit is a significant accomplishment that should be the primary focus, rather than spreading innovation too thin across multiple areas.

Finding product market fit is the top problem any entrepreneur faces, and it's about the practical nitty-gritty hustle rather than theoretical concepts.

Product Market Fit (PMF) occurs when a startup has built a product that customers love and are using, shifting the focus from defining customer needs to scaling the business. When you're pre-product market fit, your main focus should be on finding that fit, while post-product market fit, your priority shifts to maintaining and scaling that fit.

When gauging product-market fit, if you have to ask whether you've achieved it, you likely haven't. It's crucial to be honest about your startup's performance and growth potential.

The key to achieving product-market fit is to continue iterating until you find something that resonates with users, rather than relying solely on metrics like signups.

It's crucial for startups to think harder about achieving product-market fit and to be honest about whether they have it, especially in uncertain economic times.

Mattermark found product-market fit very early, which is a rare and fortunate occurrence in the startup world.
