About Session
Session shipped a protocol rewrite and a paid tier, then went publicly broke — the founder is asking users to bail it out.
Session is simultaneously in its most ambitious technical phase and an open funding crisis. Protocol V2 — re-implementing forward secrecy and layering post-quantum cryptography on top of Session's onion-routed transport — has been announced, and the Session Pro paid tier exited beta planning into a December development update. Then in March, cofounder Chris McCabe published a personal appeal saying the project cannot continue developing without user support, and the public feed has been quiet since.
