The Briefing

A 32-month CAC payback period in the $10M–$50M ARR band signals just how expensive growth has become for mid-market SaaS companies—nearly triple the 12-month gold standard and a clear marker that capital efficiency, not just growth-at-any-cost, now separates survivors from casualties. This metric anchors today's Q1 private company benchmarks, which Kellogg continues to refine as the de facto scorecard for strategic finance leaders navigating a market that rewards durability over blitz-scaling. The fresh security benchmark on agentic defense systems adds urgency: AI-powered products may accelerate growth vectors, but they also compress payback windows if deployed with discipline. Watch whether CAC payback compression becomes the defining CFO mandate for H2 2024.
