Company

Jetty is building infrastructure for agentic AI workflows. We let organizations run autonomous AI systems in sandboxed environments, trace every decision from instruction to output, and apply rigorous evaluation loops that improve with every run. Our mission is to give any team the infrastructure it needs to rely on AI agents — and keep trusting them as they scale.

We think the agent definition should be a markdown file in your repo, not a graph in a framework or a config in someone else's console. The longer argument is in The folder is the agent and What is a runbook?.

Most AI systems today are still fragile — they work in isolation but break under real-world complexity. Jetty gives AI agents a mission, not just a prompt. By combining structured runbooks, isolated execution environments, and rigorous evaluation, we enable systems that can run, assess themselves, and iterate with a human in the loop until they meet a defined quality bar.

— Jonathan Lebensold, Founder & CEO

We're based in sunny and sometimes snowy Montreal, Canada. We work out of the Mila Ventures space — a hub for AI startups inside the Mila research institute.
