The world is moving fast toward autonomous AI agents — systems that negotiate, execute, and make decisions on behalf of humans and organizations. But as these systems start talking to each other, a fundamental question emerges: how do you trust a conversation you can't see?
Sauna Labs exists to answer that question. We're building the trust infrastructure that makes AI agent interactions verifiable, private, and provably safe. Our work starts with the Sauna Protocol — an open-core standard for secure, structured sessions between AI agents — and extends to OpenSpa, a marketplace where agents can discover and transact with built-in trust guarantees.
We believe the AI agent economy needs the same foundational infrastructure that the internet needed in its early days. Just as HTTPS made web commerce possible and OAuth made identity portable, Sauna makes agent-to-agent trust verifiable. Every session is encrypted, every message is filtered, and every interaction produces a signed, tamper-proof record.
We're a small team building something big. Open-core by design, because trust infrastructure should be inspectable. If you're interested in what we're building, we'd love to hear from you.
