Infrastructure for AI agents.
That's all we do.

We started Cairn because we kept seeing the same problem. Companies would build an AI agent that worked beautifully on a developer's laptop, then spend weeks trying to get it running reliably in production. Docker configs, process managers, SSL, monitoring, crash recovery — none of it related to the agent itself, all of it necessary for the agent to be useful.

We come from cloud infrastructure and DevOps. We've built deployment pipelines, managed production servers, and dealt with the operational side of keeping things running when they need to run all the time. AI agents are a new category of workload, but the infrastructure problems they create are familiar: uptime, isolation, security, monitoring, and the ability to recover from failure without human intervention.

Every agent we host runs on its own isolated cloud instance. We don't do shared hosting, we don't co-locate tenants, and we don't access your conversations or data. You bring your own API key from whatever provider you use. We handle the server, the networking, the process management, and the monitoring. If your agent crashes at 3am, it restarts automatically and we get an alert. You sleep through it.

We keep the operation small on purpose. We'd rather run infrastructure well for fewer clients than scale prematurely and let reliability slip. If you want to know more about how we think about agent infrastructure, read what we've written, or just email us.
