ICP Scoring for Founders Who Do Their Own Sales

Most ICP scoring content is written for a RevOps or growth-marketing audience with a CRM full of clean data and someone whose job is to maintain the model. If you're a founder doing your own sales, or one of two or three people who all also have another full-time job at the company, that context doesn't apply, and you don't need it to. Here's a version scoped to what you can actually run yourself.

Start with fewer criteria than feels responsible

Three to five, not fifteen. Industry, size range, geography, and one timing signal is usually enough to be useful. See Ideal Customer Profile for the reasoning, a longer list of criteria feels rigorous but usually just means nothing gets filtered out in practice.

If you have zero closed customers yet

Every ICP guide assumes you have won customers to derive patterns from. If you don't, work backward from the problem instead: who feels the exact pain you solve, urgently enough that they're already spending time or money on a worse alternative (a manual process, a competitor, a spreadsheet). That's your starting ICP, revise it after your first five to ten customers, don't wait for perfect information you don't have yet.

A scoring method you can run without a spreadsheet macro

Points per criterion, summed to a number out of 100: industry match worth the most (companies outside your industry are rarely worth pursuing regardless of size), size and geography next, a timing signal last. See the full breakdown in firmographic scoring, or just plug a real company into the ICP Fit Score Calculator and see the number in under a minute.

Score before you call, not after

The easy trap is scoring retroactively, deciding a company was a good fit after a call went well, which just reinforces whatever bias you already had. Score candidates before any contact, using only firmographic and public signals, then see if your actual close rate tracks the score bands. If it doesn't, the criteria need adjusting, not the score.

Revisit the criteria every ten to twenty closed deals

Your ICP written in month one, before you had customers, will be wrong in some way, that's expected. The fix isn't getting it perfect up front, it's checking it against reality regularly and adjusting. A founder doing their own sales has an advantage here that a large team doesn't: you're on every call, so you have the pattern-matching data in your head even before it's in a spreadsheet. Write it down before you lose it to the next quarter's noise.
