Founder profile

Kirill Abramov

Founder & CEO, UmbrellaX LLP

Building a privacy-first messenger and backend platform for one billion users — under a jurisdiction outside the Five Eyes alliance.

Background

Kirill Abramov is the founder of UmbrellaX LLP, a Kazakhstan-based privacy company building a messenger and backend platform engineered for one billion users from day one. He is the author of Umbrella Protocol, a source-available cryptographic stack built on IETF MLS (RFC 9420) with post-quantum extensions, targeting a state-level adversary threat model (Tier D). His work spans the full stack: a 167-microservice Rust backend, iOS and Android clients, a self-hosted email service, and the public editorial operations of umbrellax.io. Kirill's approach is grounded in privacy-first design, self-hosted infrastructure, a jurisdiction outside the Five Eyes alliance, and transparent cryptographic review by independent auditors.
