The 4 Signs of Founder-Market Fit

James Currier · NFX Free Intermediate

Currier's whole argument is that founder-market fit is more than the one line on a resume that says 'domain expert'. He breaks it into experience, obsession, founder story, and personality, which is exactly why a pair can hold the fit between them: your co-founder may carry the domain, while you may carry the obsession, the story, or the personality the market trusts. Read it as a starting point for asking which pieces of fit each of you actually holds, not for deciding who is 'the fit'.

• Domain experience is only one of four signals of fit, so a founder without the domain can still be a real source of fit through obsession, story, or personality
• The piece notes fit is weighted differently by role (the CEO carries more industry-story weight, the number-two is often technical), which is a clean frame for splitting it across a complementary pair
• Fit is something you can build toward, not a fixed label, so the question is less 'who is the fit' and more 'what does each of us need to go earn'
