Kestrel AI is an AI-native cloud incident response platform that brings self-healing to cloud infrastructure. It monitors Kubernetes and cloud infrastructure continuously, identifies root causes of incidents, and generates exact fixes so issues can be resolved in seconds rather than hours. The platform unifies ops and security, replacing manual triage with autonomous investigations and human-in-the-loop remediations, with fixes applied directly to clusters or via GitOps pull requests for ArgoCD and Flux. Kestrel AI is based in San Francisco and is part of Y Combinator's Fall 2025 batch.
