The Cloud Company That Wants Every Branch to Feel Like Production
Upsun hides the plumbing beneath modern applications, then gives developers a full-stack rehearsal room for every change. Its wager is that the next cloud winner will sell fewer dashboards and more confidence.
Okteto
Okteto is a developer platform that moves Kubernetes development, preview, and testing environments into the cloud. Founded in 2018 by three former Atlassian, Docker, and Google engineers and backed by Y Combinator, Okteto lets developers spin up production-like environments with a single command, sync code changes live in seconds, and automatically create preview environments for every pull request. In 2025 the company extended the same infrastructure to AI coding agents, giving each agent its own isolated, production-like environment to build, test, and verify code at scale.
