Product

One product for
confidential collaboration

Calls, rooms and chat that assume the network is hostile — because for the conversations that matter, it is.

Encrypted video & screen share

HD calls, multi-party, screen sharing and recording — every track sealed with a key the SFU never sees.

Confidential deal rooms

Spin up an ephemeral room with documents, NDAs, parties and an audit trail. Built for M&A, diligence and legal.

Server-blind chat

In-call and async messaging encrypted end to end. The relay stores ciphertext only — not metadata theatre, real blindness.

Client-side keys

Each room's key is generated in your browser and shared only through the invite link — never sent to our servers.
