PMF Method is a hands-on program designed by First Round to help B2B founders systematically achieve and scale product-market fit. The program introduces a unique framework that breaks down product-market fit into four concrete levels—Nascent, Developing, Strong, and Extreme—across three core dimensions: Satisfaction, Demand, and Efficiency. Through a blend of tactical sessions, real-world case studies, and founder-driven exercises, PMF Method guides startups through the nuanced journey of building repeatable, scalable businesses. The program leverages insights from hundreds of early-stage startups and features deep dives into how companies like Looker, Ironclad, Plaid, and Lattice navigated their own paths to PMF.
