Mosslet

Mosslet is a privacy-first social network built as an alternative to Facebook, Twitter, and Instagram. It’s funded directly by users rather than ads or data sales, with Personal, Family, and Business tiers and a 14-day free trial on each. Zero-knowledge, post-quantum encryption covers posts, journal entries, audio messages, circles, and direct conversations, and the codebase is open source so anyone can verify how it works.

Family plans use consent-based guardianship: a guardian can only see what a managed member shares after that member has agreed to it, and journals stay private regardless. Business plans add org separation, a zero-knowledge audit log for admins, and cross-circle file sharing, aimed at teams that want Slack-style collaboration without a third party able to see their files.

Founder Mark Thayer built Mosslet solo using Elixir and Phoenix LiveView, after reading Shoshana Zuboff’s The Age of Surveillance Capitalism convinced him to teach himself to code. The company, Moss Piglet Corporation, is a public benefit corporation rather than a venture-backed startup, and Mosslet is the first of two products under that banner.
