Ehsan's Growth Analysis

PostHog weaponized transparency. They publish their revenue numbers, board meeting notes, and even employee compensation formulas. Sounds crazy. It works. When a startup evaluates analytics tools, PostHog's public information provides more confidence than any sales deck. The all-in-one play (analytics + feature flags + session replay + A/B testing) is the real growth lever: companies consolidate from 4 tools to 1, saving $2K-5K/mo. That consolidation pitch converts at 3x the rate of point-solution pitches. Also — 80 employees doing $30M+ ARR is capital efficiency that would make investors emotional.
