Rahul Vohra's method turns product-market fit from a feeling into a number you can act on — and when your product is evolving at agent speed, you need that anchor or you won't notice the floor shifting.
Vohra's framework, published through First Round Review, centers on one deceptively simple survey question: how disappointed would you be if this product disappeared? Cross the forty-percent threshold of "very disappointed" and you have something real. Below it, you have work to do. The real leverage comes from segmenting the responses — find the cohort already loving you, read their own language back to them in your copy, and then split your roadmap deliberately: deepen what the lovers rely on, and remove the specific friction blocking the persuadables from joining them.
The method was built for software that changes on a human shipping cadence. Agents compress that cadence to days or hours, which means your PMF score can decay before your next survey cycle even opens. The practical translation: run the disappointed-user signal continuously rather than quarterly, let it feed directly into whatever backlog your agents are pulling from, and treat the persuadables' objections as a live queue rather than a planning input. The human judgment call — which objections are worth fixing versus which signal the wrong customer entirely — stays yours. That distinction is where founders earn their keep.
- Instrument the disappointment question as a continuous signal, not a quarterly ritual
- let agents process the persuadables' friction into ranked backlog items but keep a human deciding which objections reveal the wrong customer
- read the lovers' verbatim language into your positioning before you let any agent rewrite it.
