Join the waitlist to lock in early access pricing before general availability.

Ship like a normal developer
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.
