The Briefing

A CAC payback period of 32 months in the $1M–$10M ARR band signals either patient capital or poor unit economics—and the line between the two has rarely mattered more. This metric, extracted from Q1 private company benchmarks, sits at the heart of today's briefing: a debate over whether growth-at-any-cost has truly died or merely hibernated, fresh analysis from Dave Kellogg on operational rigor in downturn conditions, and new benchmarks on AI-powered security where deployment speed increasingly trumps perfect economics. The tension is structural: enterprise buyers now demand AI capabilities while scrutinizing every dollar of spend. Watch whether Q2 data shows payback compression or further drift into founder-funded inefficiency.
