About Us

Making the Internet More Reliable, with Al

Our vision

Built for the engineers who keep the world running.

Infrastructure should be resilient, human-centered, and ready for anything. We're reimagining on-call workflows with intelligent paging and Al-driven response, helping engineers sleep through the night while keeping mission-critical systems in healthcare, finance, and beyond running smoothly.

We believe that Al agents shouldn't just alert — they should investigate, diagnose, and resolve. That's the shift we're making possible.
