Privacy happens in the background
We built this for teams who want structural guarantees, not policy promises. You shouldn't have to become a cryptographer to stop accumulating liability.

Build with Stoffel today
Self-host the entire stack and dompute on sensitive data without storing it, sharing it, or trusting anyone to see it.
Application SDKs
Integrate answers-only computation directly into your backend or data science workflows. You send code and encrypted inputs—not raw user data—and receive only the allowed result.
git clone https://github.com/StoffelLabs/Stoffel
Copied
Stoffel-Lang
Write privacy-preserving logic that explicitly defines what outputs are allowed. Stoffel-Lang makes data leakage a compile-time error—not a policy decision.
git clone https://github.com/Stoffel-Labs/Stoffel-Lang
Copied
Secure Runtime & Networking
Under the hood, Stoffel runs on a high-performance MPC virtual machine with encrypted, decentralized networking. No party—including you—can access raw inputs.
