It moves you past 'we went viral' anecdotes into concrete steps for narrowing your buyer, running discovery, and reading whether you have real pull.

This framework treats persona as one of four levers, alongside problem, promise, and product, that you pull when growth or product market fit stalls, asking directly whether your target persona is too narrow, too broad, or needs to be replaced altogether. It gives you benchmarks for how a company's readiness changes as it moves from a handful of early customers into a mature account base. Useful for checking whether you have gotten specific enough for the stage you are actually at.
