The Briefing

A 32-month CAC payback period in the $5M–$50M ARR band suggests either go-to-market bloat or a structural recalibration of what efficient growth now costs in saturated categories. The figure anchors today's private company benchmarks, which arrive as SaaS founders navigate a market that rewards profitability over land-grab velocity—though the rising voice in strategic finance continues to argue for nuance over dogma in capital allocation. Meanwhile, the fresh benchmark on AI-powered security reveals how agentic defense systems are shifting enterprise buying patterns, potentially lengthening sales cycles and inflating payback windows further. Watch whether Q2 data shows compression or if 30-plus months becomes the new normal for mid-market SaaS.
