The Briefing

A 32-month CAC payback period in the $10M-$50M ARR segment confirms what many suspected: efficient growth has become negotiable again, at least for companies convinced their AI credentials justify the burn. The metric sits uncomfortably against recent benchmark data suggesting enterprise buyers remain skeptical of agentic security claims—purchasing cycles haven't compressed despite vendor promises of autonomous defense. Kellogg's recent work dissecting go-to-market efficiency offers useful counterweight to the prevailing "growth at reasonable cost" ambiguity, particularly for mid-market SaaS operators caught between board pressure to show momentum and investor demands for discipline. The real test arrives in Q2 earnings, when payback trajectories either validate current spending or trigger another round of unit economics religion.
