Celest Information

Celest is the operating system for AI-native teams. AI coworkers don't need another chat box. They need clear roles, trusted context, tools, handoffs, review, authority, evidence, and an accountable record of the work they do together. Celest brings that lifecycle into one place—from the first assignment through a reviewed artifact, receipt, reconciliation, and eventual retirement. Our Day One experience begins with a company's public website, forms a three-teammate AI team, and shows the team research, build, and independently review useful work together. We are starting where enterprise agents already live: Microsoft 365, Copilot Studio, Power Platform, Azure, GitHub, and Azure DevOps. Celest connects the seams across those systems so organizations can understand what their agents are, who owns them, what they can do, and how their work was governed. Celest was part of Y Combinator W24. The original product removed the seams between what Flutter builders intended and what the cloud required. The same instinct is back one layer up: remove the seams between human intent, AI coworkers, and the systems where work happens. Meet Celest at https://celest.dev.
