Build with Sensitive Data. Keep It Where It Lives
Collaborate without giving data away — analytics, matching, and aggregation run where your data lives. You keep custody; we return only results.

Stoffel is a MPC privacy stack that lets you run sensitive computations where the data lives, without moving or exposing it.
Stoffel is a MPC privacy stack that lets you run sensitive computations where the data lives, without moving or exposing it.
No risky data transfers
Write your logic directly in Stoffel Lang.
Code runs without exposure
Execute securely on our MPC-powered VM.
Only answers are shared
Integrate results into your apps with our SDKs.
Build logic in Stoffel Lang
Write the computation you want (analytics, ML steps, matching, key ops) and mark what can be revealed. Simulate locally and unit test—no crypto deep dive.
Run it reliably on Stoffel VM
A production engine coordinates the multi-party run with predictable latency, retries, and checkpoints—so you get one consistent result, not surprises.
Integrate with Stoffel SDKs
Drop MPC into your app: language SDKs for Rust, Python, JS/TS, plus application-specific SDKs (web framework middleware, data/connectors, queue/orchestration adapters). You keep your stack; we return answers-only outputs.

The Stoffel Stack
Use the full stack or each as you need — your choice.
Write code as normal
Mark data as private or public
Stoffel compiler
• Data stays private
• Computation happens
• Results are shared
STOFFEL LANG
Write the computation you want.
Describe analytics, ML steps, matching, or key ops (can be changed for other kinds of algorithms/processes). Mark what can be revealed—we handle the hard parts. Simulate locally and unit test.
Familiar, readable syntax
Secret/public types + explicit reveals
Local simulation and unit tests
