Most teams write an ICP once and let it quietly rot for years. Targeting drifts from who actually buys, and win rates fall. A dynamic ICP gets rebuilt each half from your own won and lost signals. You add proactive intent, then split the definition into the books your team works.
Read time: about 9 minutes.
Pull your last half of won and lost deals into one sheet before Friday. That single sheet is the raw material for every other step. Most teams argue about the ICP from memory and stale decks. The deals hold the truth about who bought and who walked.
Why this move: you cannot rebuild a definition from opinion. You rebuild it from what closed.
Start here: export closed-won and closed-lost from H1, with reason codes and firmographics.
Ignore this week: do not rewrite messaging, do not rebuild scoring, do not touch tiers yet.
