Most founders write their ICP once, during fundraising, as a line in a deck: "seed and Series A companies scaling from ten to fifty people." That line works for an investor. It's useless for outbound, content, or a sales call, because nothing about it tells you who to message, what to say, or when to say it. This worksheet fixes that in five questions, worked through in order, in about thirty minutes.
Why a broad ICP costs you more, not less
The instinct to keep the ICP wide feels like it protects pipeline. In practice it does the opposite. A wide ICP means every piece of content, every cold message, and every case study has to speak to everyone a little, which means it speaks to no one well. Reply rates drop, content stops converting, and you can't tell whether the problem is messaging, timing, or targeting, because you were never specific enough to isolate which one in the first place.
A narrow ICP also tells you when to stop narrowing. Once you have five paying customers who share the same profile, that's real signal. Broaden from there, deliberately, one variable at a time. Don't broaden before you have that proof, no matter how much the segment feels too small.
The five questions, in order
Work through these in order. Each one narrows the next. Skipping ahead to "industry" before you've nailed the trigger event is the most common way this exercise drifts back into a segment description.
- What just happened to them? Not a demographic, an event. "Closed a seed round in the last ninety days" is a trigger. "Early-stage startup" is not. If you can't name the event, you don't have a trigger yet. Go back and find one.
- Who personally feels the pain, by title? Not "the company." One person, with a title, who is losing sleep over this specific problem right now. For a GTM Sprint that's usually the founder or CEO, before there's a dedicated Head of Sales.
- What's the symptom they'd actually type into Google or say out loud? Write the sentence the way they'd say it to a friend, not the way you'd describe it in a pitch. "Outbound isn't working" beats "inefficient top-of-funnel conversion."
- What size and stage makes this solvable in one engagement? Too small and there's no budget. Too large and the problem is political, not operational, and no fractional engagement fixes it in a Sprint. Put a real headcount and funding range on it.
- Where do twenty of them already exist, today? Not where they theoretically exist, where you could open a browser tab right now and find twenty of them. LinkedIn Sales Navigator, an accelerator alumni list, Crunchbase filtered by funding stage and date. If you can't find twenty, the definition is still too specific or too rare to build a motion around.
Worked example
| Question | Answer |
|---|---|
| Trigger event | Closed a seed round in the last 90 days, 3 or more open sales/marketing reqs, no dedicated Head of Growth yet |
| Who feels it | Founder/CEO, still doing every sales call personally |
| The symptom in their words | "Outbound isn't working" or "I don't have time to sell anymore" |
| Size and stage | Seed to Series A, 2 to 15 million raised, 8 to 35 people |
| Where 20 of them exist | YC/Techstars/local accelerator alumni directories, founder's own LinkedIn first-degree network, Crunchbase filtered on funding stage and date |
This is the exact profile a Growth Sprint (ICP definition plus a GTM systems audit, built as a fixed-scope two to four week engagement) is built to sell into. Notice what's missing: industry. At this stage, the trigger event and the buyer's felt pain matter more than vertical. Industry becomes a useful filter later, once you're narrowing a proven ICP further, not before you have one.
What "narrow enough" looks like
You're done when a stranger could read your five answers and pick the right companies out of a list of a hundred without asking you a single follow-up question. If they'd still need to ask "wait, what counts as early-stage," it's not narrow enough yet. Go back to question one.
