Founders often create complex plans and documents to avoid the simple, hard, and uncomfortable task of selling. Just as getting stronger requires consistently lifting heavier weights, finding product-market fit requires consistently doing the core work of talking to customers and trying to sell.
Product-market fit isn't a sudden switch but a palpable shift in momentum. As a founder, you feel the change from pushing against the current (hard selling with little traction) to suddenly being pulled by it (easier sales, inbound interest). This directional change in velocity is the clearest signal that you're onto something.
Creating elaborate decks and spreadsheets provides a feeling of productivity but is often a sophisticated form of procrastination. It allows founders to delay the core, uncomfortable task of directly engaging potential customers and facing rejection, thereby making no real progress on finding product-market fit.
Founders often believe their product is flawed when facing rejection. However, if they're only speaking to 1-2 potential customers a week, the core issue isn't product-market fit. The real problem is an insufficient number of conversations to validate or disprove any hypothesis. You haven't earned the right to have a PMF crisis yet.
