For creative agencies, design studios, and launch teams.
Your campaign doesn't leak until you decide it leaks.
Pitch decks, unreleased designs, and embargo-sensitive timelines belong behind encryption. Koaich lets you collaborate internally and share with the client without a single cleartext copy living on a third-party server.
What you get
Encrypted file sharing for design assets
Assets are noise at rest. Per-file encryption with key wrapping into the message envelope.
TTLs on pre-release pitch decks
Pre-release work has a short half-life by default. The campaign drops on your timeline.
Group messaging with auto-rotation
When a contractor rolls off, encryption keys rotate automatically. They can't read this quarter's strategy thread.
Claim-once external delivery
Clients without Koaich get a one-shot read link. Forwarding doesn't transfer access.
The underlying cryptography
Every claim above is grounded in a specific primitive. Not marketing.
- →Per-file encryption
- →Claim-once HMAC-signed external links
- →MLS group rooms with forward secrecy
