We build what others won't
We ship our own products, and we take on yours. Hard cryptography, weird ideas, adult subject matter, the work that gets politely declined everywhere else lands here and gets built.
Private by architecture. Not by promise.
NutHub is an iPhone app for the things you would never hand to someone else's cloud. Content is encrypted on the device with a key derived from your password — or provisioned through iCloud Keychain if you signed in with Apple. What reaches the server is ciphertext. Photos and video included: the stored bytes are not images.
There is no server-side decryption path. Not one we choose not to use — one that does not exist. We cannot read your content for support, for a court, or out of curiosity, and the honest cost of that is printed in the app: lose both your password and your recovery code and your content is gone. The same sentence that makes it private makes it unrecoverable.
The intelligence runs on the phone, on Apple Foundation Models. Your content has no network path to a third-party model provider, because we never built one.
- E2EE
- key derived on device
- AI
- Apple Foundation Models, on-device
- Server
- ciphertext only
- Media
- encrypted, not stored as images
Someone had to build this one, and three people we know wouldn't.
Bring us the one nobody else would take.
You don't need a discovery phase to find out whether we're interested. This is the ledger. Find your project on it.
- Encryption you actually have to get right
- An adult-audience product two studios already declined
- On-device AI, no server, no vendor reading the payload
- A market so specific it has maybe four thousand people in it
- A regulated corner nobody wants to read the rules for
- The idea you've stopped telling people about at parties
- Your competitor's app, cheaper
- Blockchain with the cryptography left out
- "An AI wrapper, but for X"
- A brief where nobody can say who it is for
Most ideas are on neither list. The left column is what we are best at, not the price of entry — if you have an app you want built, we want to build it.

Five fields, and a person who can actually build it reads what you send. No call booked to arrange a call.
