Product-Market Fit
When your product satisfies strong market demand.
Definition
Product-market fit (PMF) describes the stage where a startup has built a product that enough customers want, creating organic growth and retention. Coined by Marc Andreessen, it's the point where the market "pulls" the product out of the company. Before PMF, everything is an experiment. After PMF, the focus shifts to scaling.
Why it matters for founders
Without product-market fit, no amount of marketing, fundraising, or hiring will save your startup. Investors look for PMF signals before writing checks. It's the single most important milestone for any early-stage company.
Example
A SaaS tool for freelancers notices that users who complete onboarding retain at 85% after 90 days, refer 2+ friends each, and usage grows 15% month-over-month without paid acquisition. That's PMF.
How Foundra helps
Foundra's Validate phase is designed to help you find PMF faster. The Objection Map card surfaces why people won't buy, and the Proof Signals card tracks the evidence you need before scaling.
