# Message Market Fit

> Run Brite outbound as a truth system using the MSPA matrix (Market × Segment × Persona × Angle) with three modes — MAP for new market entry, ITERATE for post-results iteration, DIAGNOSE for stuck pipeline — under the barbell 80/20 allocation and Kellen's 10 Laws. Serves BDRs, RevOps, and marketing operators who need systematic experiment design, not one-shot campaigns. Triggers on message-market-fit, mmf, test messaging, test angles, which message works, experiment design, what resonates, potency test, MSPA matrix, barbell outbound, stuck pipeline, diagnose outbound, iterate campaign, Kellen's laws. Receives from creative-angles (A dimension of the matrix), campaign-analysis (ITERATE input as docs/campaigns/{entity}/analysis-.md), gtm-strategy (MAP persona profiles), and situation-mining (optional per-account worldview); hands off to outbound-playbook (executes experiments, BC-2722 pending) and campaign-debrief (captures transferable learnings). Adapted from Revgrowth1/ai-gtm-workflows workflow 07 (MIT).
