Product-market fit is the critical milestone where a product meets real market needs so effectively that it gains traction organically. Marc Andreessen described it as 'being in a good market with a product that can satisfy that market.' It's often measured by user retention, organic growth, and the difficulty customers would face if the product disappeared.
