ContractSpec for AI-native systems
The contract-first substrate for AI-native software.
ContractSpec gives technical teams the open substrate for software that agents can read, regenerate, and operate safely: typed contracts, aligned APIs, data, interfaces, tools, and evidence. Managed CompanyOS is the packaged operating application built on top, not a replacement for the foundation.
What the site should make clear
This is the substrate below AI-native products.
ContractSpec exists for teams that need software, interfaces, data, and agent tools to keep obeying the same explicit product rules as AI accelerates every edit.
- Keep the code and the standards you already use.
- Stabilize one module at a time instead of rewriting your app.
- Move into Managed CompanyOS only when you want the packaged operating application on top.
Why teams end up here
Agents do not break software because they are fast. They break what is implicit.
Once agents touch code, data, UI, workflows, and tools, the failure mode is not simply bad generated code. It is that the company cannot state the system rules precisely enough for every surface to stay aligned.
Implicit rules drift first
Prompt chains and AI edits move faster than the product rules they are supposed to respect.
Surfaces stop agreeing
API, UI, database, events, and MCP tools evolve independently unless something explicit keeps them aligned.
Teams lose safe regeneration
Without a stable contract layer, every regeneration feels like rewriting production in the dark.
The open system
One explicit layer for software, agents, data, and interfaces.
ContractSpec is broader than code generation. It is the contract layer, runtime bridges, agent-readable tool surface, dynamic interface substrate, and proof path that lets teams build AI-native software without collapsing into prompt-only governance.
Contracts and generation
Define the canonical behavior once and derive the implementation surfaces from it.
Runtime adapters
Bind the same source of truth to REST, GraphQL, React, MCP, and operational flows.
Harness and proof
Replay, evaluate, inspect, and verify how the system behaves before you trust automation with more.
Managed CompanyOS bridge
Adopt the packaged AI operating system for companies when you want the managed application built on the same contract substrate.
Where the substrate shows up
Explicit contracts show up where AI-native teams usually lose control.
The promise is not magic generation. The promise is that the same product rules can shape APIs, data, dynamic interfaces, and agent tools without each surface inventing its own truth.
APIs
Typed endpoints and schemas stay aligned with the same contract language the team edits.
Data
Schema, validation, and migrations are shaped by the same product rules instead of scattered implementations.
Dynamic interfaces
Forms, DataViews, adaptive shells, and entity workspaces inherit the same system boundaries instead of drifting from the backend.
Agents and tools
MCP tools and agent-facing surfaces are generated from explicit contracts rather than guessed from code.
Adoption path
Start where the risk is highest, not where the marketing says to start.
- 01
Start with one module that is already drifting or feels unsafe to regenerate.
- 02
Define explicit contracts, then bring API, UI, data, and tools back into alignment.
- 03
Adopt Managed CompanyOS when the team wants the all-in-one operating application on top of the open system.
Managed application on top
Managed CompanyOS is the application, not the OSS payload.
Use Managed CompanyOS when your team wants company brain, role-aware operations, approvals, evidence, identity, communication, billing, and integrations packaged as an operating application. The OSS substrate remains distinct and ejectable.
OSS/Core: contracts, generation, runtimes, harnesses, agent tooling.
Managed CompanyOS: the managed AI operating system for companies built on the substrate.
Choose your path
Build on the open substrate. Choose Managed CompanyOS when you want the operating application.
ContractSpec is the technical foundation for AI-native software. Managed CompanyOS is the invite-led application for teams that want the company brain, role-aware operations, and evidence loop packaged for them.
