The operating system for AI coworkers

Give AI coworkers an operating model.

Agents now span Microsoft 365, Agent 365, Copilot Studio, Power Platform, Azure, GitHub, and Azure DevOps. Celest turns that sprawl into one accountable estate—read-only first, governed action when authority is explicit.

The control plane earns autonomy. It never assumes it.

The gap

Microsoft is building the platform.
You still own the seams.

An agent can cross Entra, Microsoft 365, Copilot Studio, Power Platform, Azure, GitHub, and Azure DevOps. Its identity, ownership, tools, spend, and risk usually cannot. Each admin center is truthful about its slice—and blind to the whole.

The missing product is not another dashboard. It is the compass that turns scattered evidence into one accountable record, one review queue, and eventually one governed path to action—every field traceable, every gap kept honestly unknown.

The loop

Start read-only.
Earn the right to act.

Microsoft’s native tools help teams build agents. Celest helps them operate what they have already built. Every consequential step keeps actor, scope, rationale, approval, and receipt visible.

The wedge

Start with the Microsoft Agent Estate Review.

A fixed-scope, read-only operating review for organizations that already feel agent sprawl inside Microsoft. Software gathers and normalizes the evidence; together we turn fragmented ownership, capability, usage, cost, and risk signals into one accountable operating plan.

What you receive

  • 01Normalized agent inventory with source and join provenance
  • 02Ownership, lifecycle, tool, MCP, usage, cost, and risk findings
  • 03An executive posture report that preserves unknown and unavailable
  • 04Prioritized reviews and proposed work with evidence, scope, and expected effect
  • 05An authority workshop and 30 / 60 / 90-day control-plane plan

Customer zero

Built on real seams,
not a market map.

Celest exists because running an agent-native company on Microsoft already forces you across disconnected identities, admin centers, tools, and handoffs. Every claim is labeled by evidence. Live means implemented and tested in a bounded development environment—not a production service.

Live · Dev

Estate Review API

Fail-closed scoped sync, inventory, detail, findings, and local acknowledgement. Microsoft-facing routes remain read-only.

Live · Dev

Canonical control-plane contracts

Dedicated agent, evidence, finding, and receipt models keep provenance and unknown state visible across surfaces.

Live · Dev

Power App + static demo

A signed-in Code App and a safe public preview both tell the same review story without pretending illustrative data is live.

Experimental

Headless Microsoft operations

Copilot Studio model and tool discovery plus agent create, save, and publish have been exercised end to end; private contracts remain quarantined.

Celest's cloud-infinity bird mark

YC W24 → now

Same instinct.
One layer up.

Dillon created Amplify Flutter at AWS, then took the original Celest through Y Combinator as “the Vercel of Flutter.” It removed the seams between what a builder intended and what the cloud required.

Now the builders are humans plus agents, and Microsoft is assembling the substrate where they work. The missing layer is not another copilot. It is the control plane and compass that keeps that voyage legible: identity, ownership, evidence, authority, cost, and receipts.

Remove the seams between intent and the cloud.
