Governed end-to-end execution
Turn an objective into a verified outcome.
Real work spans many systems, policies, and teams, and today it holds together only because people coordinate it by hand. Crescevo runs the complete path, evidence, authority, decisions, execution, and verification, so people set the direction and the judgment while the platform completes the work and proves the result. Every effect produces a receipt: what ran, what was observed, and whether the intended outcome actually occurred.

Building blocks
Build on six building blocks. Here is what each one does.
Evidence
Store every claim your software makes, linked to the sources that support or contradict it.
Learn more →Artifacts
Version every output your software produces, with a durable, immutable revision history.
Learn more →Sessions
Run long-lived work with a typed record of everything that happened.
Learn more →Workflows
Move work through explicit states with proposals, approvals, retries, and checkpoints.
Learn more →Controls
Enforce tenancy, permissions, authority, and approvals on every write.
Learn more →Execution
Run approved commands as supervised effects, with a receipt for every one.
Learn more →How it works
Model, ground, decide, execute. The kernel revalidates everything.
- 1
Model
Declare artifacts, workflows, and controls in a blueprint.
- 2
Evidence
Work produces claims bound to sources and verification state.
- 3
Decision
Proposals are approved under policy and authority.
- 4
Execution
Authorized commands run as receipted effects.
Use cases
Built for consequential work that must be proven.
Regulated and reviewed workflows
Build operational tools where every output must be traceable to its evidence and to an authorized decision.
AI outputs that must be auditable
Ground model outputs in verifiable claims, gate them behind approvals, and keep a durable record of what shipped.
Multi-tenant operational software
Isolate tenants at the data layer and enforce authority and policy on every write, not in the interface.
Architecture and trust
The kernel decides what is true, legal, and authorized.
A Rust and Postgres kernel is the system of record for sessions, artifacts, evidence, decisions, commands, effects, and authority. The interface renders backend-supplied legal actions; the kernel independently revalidates every command. Tenancy isolates every record.
