description: Define a B2B ICP tight enough to write one email to, and build the named account list. Use before any outbound.

Build an ICP you can act on today.

**Read first:** `01-voice/skills/icp-profile/SKILL.md` if it exists. That file is the profile this list is built from — rebuilding it from scratch produces a second, slightly different definition of the same customer, and then two skills downstream disagree about who you sell to.

1. **Three dimensions:** company (size, sector, stage), role (the person who feels the pain, and the person who signs — often different), and trigger event (what makes this urgent now).
2. **Start from who already pays.** If there are existing customers, pull them — size, stack, how they found you. The ICP describes them, not an aspiration. If there are none, mark it a hypothesis.
3. **The test:** name twenty companies that fit, sourced from somewhere real — job boards, your own signup domains, forum posts, changelogs. Say where each came from. If you cannot find twenty, the ICP is too broad; do not invent them to hit the number. Do this before writing any copy.
4. **Build the list** — twenty named accounts with the specific person at each, and the trigger you think applies.
5. **Disqualify explicitly.** Who is *not* the ICP, so time doesn't leak into bad-fit conversations.
6. Write to `03-b2b/icp.md` — `02-routines/accounts.md` in Day Zero.
