Bitwarden

Bitwarden is the open-source password manager Kyle Spearrin launched in 2016 as a direct response to LastPass's closed-source, VC-backed model. The entire codebase is public on GitHub, which is both the product's strongest security argument (anyone can audit it) and its best marketing channel (the open-source community became evangelists). Bitwarden bootstrapped to $5M+ ARR with a small team by offering a truly competitive free tier: unlimited passwords, unlimited devices, and all core features free. Revenue comes from individual Premium plans ($10/year — intentionally cheap) and Teams/Enterprise plans for business password management with SSO, directory sync, and admin controls. The pricing philosophy is the opposite of competitors: make the free tier so good that individuals adopt Bitwarden personally, then businesses naturally want to standardize on it when the same employees recommend it to their IT department. Bitwarden's self-hostable option (run your own server with Docker) captures the security-conscious enterprise segment that no SaaS password manager can touch.
