Mosaic · AI cost and governance San Francisco · Hong Kong · Lisbon

Your AI estate has sprawled. Get cost, control and audit back.

Mosaic is one control layer over every model, agent and data source, in every cloud. It runs inside your perimeter.

Each cloud governs what runs on it, and nothing governs the rest. Separate bills, separate rules, gaps in the audit trail. That is why AI projects stall before production. Mosaic connects all of it and replaces nothing you run today.

How Mosaic controls a call

Every transaction meets a traffic cop.

Mosaic checks each call before it reaches a model, an agent or a data source. Cost accounting happens in the same step as the policy checks.

GRANT

Grant permission.

Explicit permission on both the source and the destination. This agent may use this data connection, for this call.

CHECK

Check policy.

A chain of checks on every transaction. Data checks (a SQL call may only touch these fields), cost checks, and prompt checks.

CAP

Cap spend.

Budgets per application or transaction type. Calls stop when the budget is hit, such as a dev team capped at 2 million tokens.

RECORD

Write the record.

Every grant, every check, and the reason each call was approved or denied. Queryable, so you can build your own reports.

Audit trail 02 / 04

Every decision leaves a record your auditor can use.

  • 01

    Full stack, not just model calls

    Model gateways only see traffic to a model. Mosaic also governs data connections, agent-to-agent traffic and MCP tool access, under one policy and one audit trail.

  • 02

    Inside your perimeter

    On-premise or in your own cloud account. Prompts, outputs and logs stay inside your boundary.

  • 03

    Evidence an auditor can use

    Every decision is logged with who, on what authority, which policy, and the outcome.

  • 04

    Advisory that maps it to your obligations

    We map your regulatory controls onto the systems that control AI, with your risk team. Your risk team signs off.

What you actually get

Software plus advisory, with a fixed exit.

Mosaic is software we license. We set it up properly, tune it, test it, then hand it over. It runs in your network, so it is your system. Five phases, and the engagement ends when you say you can run it.

Vendor-neutral by design. Works with AWS, Azure, Google Cloud and local models. Nothing you run today is replaced.
What comes next

The same layer is a front door for outside agents.

When you are ready, the layer that governs your AI inside the business gives outside agents a governed way in. Your customers' procurement agents, and assistants like Claude, ChatGPT and Copilot, can discover and transact with you. Registered, rate-limited and logged, on your terms.
