The Briefing
A CAC payback period of 32 months in the $1M–$5M ARR band signals structural inefficiency—companies at this scale should be recovering acquisition costs in 18–24 months, not nearly three years. The gap between ambition and unit economics widens precisely when growth-stage firms face the steepest reinvestment demands, a tension Dave Kellogg has dissected with unusual clarity in his recent Q1 benchmarking work. Today's selections explore this friction: the emerging debate over whether lengthening payback windows reflect market maturity or execution failure, and fresh data on AI-powered security firms where customer concentration and complex sale cycles push payback even further. Watch whether post-AI vendors reset investor expectations or merely postpone the reckoning.
