Our story

We help teams collaborate securely and easily by protecting their data with end-to-end encryption.

Our story started when Henry Lee, at the age of 20, sparked his interest in cybersecurity and led him to start his fight for digital privacy and research cryptography further. Ten years later in 2011, he founded Cloud9 Technologies with two other friends and the head of a leading IT security institution. Since then, Cloud9 Technologies has grown into a company bringing secure collaboration to teams all over the world.

We encrypt everything to know nothing.

We create secure, zero-knowledge apps that empower people to take control of their data. Our end-to-end encryption protects information in the cloud from everyone, even from us.
