Icp Development

How vertical SaaS operators define, sharpen, and defend their ICP. Frameworks for firmographic scoring, buying committee mapping, and killing off bad-fit deals early.

What This Covers

ICP development is the work of defining which accounts you can win, keep, and expand, and then enforcing that definition in routing, scoring, and quota. It is a revenue decision that gets treated as a marketing exercise more often than it should.

Why GTM Is Different Here

Vertical SaaS makes ICP both easier and harder. The industry is already chosen, so firmographic filters like employee count carry almost no signal. The real segmentation lives in operating characteristics: how the business is structured, which system of record it runs, whether it has a dedicated administrator, how many locations it coordinates. Getting this wrong shows up as a healthy win rate and terrible retention. The teams that get it right define the profile from expansion and churn data rather than from closed-won, then hold the line by disqualifying loudly and early.
