OnlyCFO: '2026 Is the Year of Churn' — AI Alternatives Will Break SaaS Unit Economics at 18+ Month CAC Payback
SaaS finance newsletter OnlyCFO warns that AI-driven churn will break unit economics for SaaS companies in 2026. The core argument: 18+ month CAC payback periods only worked when average customer retention was 5+ years. As AI alternatives accelerate churn, that retention assumption collapses, and companies with long payback periods face existential economics. The newsletter notes that '90%+ of the software churn from AI hasn't hit yet' — companies needed time to evaluate alternatives, update processes, and build internally.
