Build on a model of how the business works.
Harness is the technology we are building to describe a business so software and AI can act on it. We plan to let developers and partners build for their clients on it without rebuilding the foundation each time, while each client owns its workspace.
Build the foundation once. Every tool after inherits it.
Automations move data between apps. They don't know that this CRM customer is that accounting account, or which system wins when the two disagree. Harness settles that once, with evidence and the owner's approval. The second and third thing you build for a client start from it.
The parts you'd otherwise rebuild for every client.
All six run locally today. How the agent builds the company model is on the Harness page.
Source survey
Reports what an unfamiliar system holds and how its records link up. Copies no values and changes nothing.
Company model drafts
The agent drafts the company model, the business's ontology. It is checked against fresh data and applied only by the owner.
Lasting context
One versioned company model that outlives the session and the AI model.
Evidence
Every value carries its source and when it was true, seen and recorded. Nothing is overwritten.
Identity and access
One object per customer across systems. Who may read each field, and what a model may see.
Ways in
Terminal, CLI, HTTP API, Python SDK and a local MCP bridge, with any supported model or none.
Your clients, your offer, our infrastructure.
We equip developers, and developers equip businesses. We don't intend to sell to every business ourselves.
Your clients
You bring and serve them, and you keep the relationship.
Your offer
You build and price your own solutions.
Recurring work
A foundation that stays current is something you can run and charge for over time.
Our part
We intend to provide the deployment infrastructure and earn from it.
There is no partner program, white-labeling, managed deployment or billing yet. Commercial terms are not written, and reselling access needs our written consent. A partner agreement comes before anyone sells on the platform.
What you can run today.
A private checkout of Harness that runs on your machine, with a made-up business to try it on. You need no cloud account, card or AI model.
