HIPAA forces healthcare to encrypt email. Paubox won by deleting the portal rivals forced on recipients.
Will it work? · our read
Killed the portal. HIPAA makes encrypted email non-optional. Paubox won by deleting the portal rivals forced on recipients — the risk is Google/Microsoft baking that convenience in natively.

Paubox: $10M raise, 4,000+ customers, 70M emails/mo (Aug 2022)HIPAA Journal: interview with founder Hoala GreevyLatka: revenue estimate about $10M ARR (2024)Paubox: Inc. 5000 five years in a rowCrunchbase: Paubox funding & profile
Revenue is a third-party estimate: Latka pegs about $10M ARR in 2024 (up from $1.2M in 2018) — Paubox has not confirmed it, so treat it as EST, not official. The hard tiles (4,000+ customers, 70M+ emails/month, $14M raised) are first-party from Paubox's own Aug 2022 funding post and are now dated (likely higher). Not bootstrapped: $14M raised over two Arthur Ventures rounds. The 'kill the portal / no passcode' positioning is Paubox's own documented claim (fact). The commoditization 'dies' thesis and the platform-native threat are our read (infer), not a stated event. We never score you.
