An ICP describes the company most likely to buy, retain, and expand. It usually combines firmographics (industry, size, geography, tech stack), behavioral signals (current solution, recent funding, hiring patterns), and qualification criteria (budget, urgency, executive sponsor).
A sharp ICP focuses GTM resources where they convert best. Companies that try to sell to 'everyone' typically have weak conversion, long cycles, and inconsistent customer success, every account is different, so nothing scales.
