// evidence over assertion

Verify your technology.
Don’t just trust it.

We build software that earns confidence through evidence you can inspect — not through our word. Closed by default, auditable by design.

umwelt

A hardened sandbox for LLM agents.

One podman container per project, closed by default. The agent sees its workspace and no network; it asks for what it needs, you decide, and every grant is logged.

How it works
PRODUCT 02 status: stealth

Why

The principle

Claims should be checkable.

Anything we ship, you can inspect: the source, the logs, the rules that bound it. A claim you can’t check isn’t evidence, it’s a slogan.

Default deny, then grant.

A system that can do anything has been trusted with everything. Our tools start with nothing and earn access one decision at a time.

State the limits.

A boundary you’re told about is a design decision. One you discover in production is a defect. Every product here documents what it does not protect.
