What I’m seeing with SaaS founders and CEOs navigating the GenAI transition — the ones who built something that worked, and are now in the gap between what they were fit for and what comes next. Post 3 of 6

Your last PMF is becoming your next constraint.

Not because you built something broken. Because you built something that worked — and then optimized it over years, in every direction. The pricing model that converted. The architecture that scaled. The go-to-market motion that closed. The customer profile that drove everything. Each was a correct choice. Collectively, they are now the thing in the way.

AI shifted what can be delivered and what customers now expect. The company stayed exactly what it was built to be. The more precisely you were fit for the last regime, the harder the move to the next one.

Pre-PMF again doesn’t mean starting over. It means finding where the current PMF ends and the next one begins — while everything you built is still running.
