Systems engineers who got tired of guessing.

Spiros and Panos met in Athens a decade ago, working opposite ends of the same problem. Spiros ran cloud operations at Mattermost and co-authored Argo CD in Practice, because the GitOps tooling needed a real book. Panos spent nine years at Elastic as a Distinguished Engineer, running the observability and infrastructure products that enterprises depend on.

Every incident, every team rebuilt production context from scratch. The deploys, the dependencies, the last rollback: none of it lived anywhere a system could reason over. It lived in engineers' heads, and when they left, the context left with them.

Tassos came at it from underneath. Two decades on the runtime primitives cloud runs on (unikernels, container runtimes), and his project urunc is a CNCF sandbox project. Three people, same diagnosis: production needs a live model, not another dashboard.
