Customer Success and Expansion

CS is now a growth function. Roles, onboarding, adoption, renewal, expansion, health scoring.

Why CS is growth

NRR > 100% is impossible without active expansion. Expansion is cheaper than acquisition. Healthy CS programs produce 30–60% of growth from existing customers. Treating CS as support cost vs growth function shapes investment.
