The Briefing

A 32-month CAC payback period in the SIM–SSM ARR band signals just how much growth-at-all-costs discipline has eroded in the middle market, where unit economics should be tightest and where most SaaS companies actually live. This benchmark anchors today's selections: Kellogg's continued excavation of what efficient growth actually means when the fog of vanity metrics clears, and a timely look at how AI-powered security startups are positioning themselves amid enterprise skepticism—a category where customer acquisition costs balloon quickly if the value prop isn't surgical. The gap between what founders promise and what CFOs will fund has never been wider. Watch whether Q2 data shows payback compression or whether capital discipline remains aspirational.
