AI agents that do real work inside your systems

We build AI agents and multi-agent systems that read approved data, call your APIs and tools, and act within the permissions you define - with a person approving the steps that carry risk.

AI Agents & Multi-agent Systems

What we build

  • 01

    Single-workflow agents

    One job - triage, quotes, reconciliation - with a success rate you can measure.

  • 02

    Tool use & MCP servers

    Typed tools and custom Model Context Protocol servers over your APIs and data.

  • 03

    Multi-agent orchestration

    A coordinator routing work to specialised agents, with shared state and retries.

  • 04

    Human-in-the-loop

    Approval steps for actions that move money, change records or contact customers.

  • 05

    Agents inside your product

    Agent features in your web or mobile app, built with the Vercel AI SDK and Mastra.

How we work

From first workflow to production

  1. 01

    Pick one workflow

    Owner, inputs, allowed actions and what success looks like.

  2. 02

    Map tools & permissions

    Which identity the agent uses and what needs approval.

  3. 03

    Build the evals first

    Real tasks plus the hard cases: missing data, failing tools.

  4. 04

    Ship behind controls

    Logging, cost monitoring and an off switch - then extend.

The agent can prepare. You decide whether it acts.

Is it a fit?

Who we build this for

A good fit if you have

  • A repetitive workflow with an outcome you can check
  • Systems the agent can reach through an API or database
  • A team ready to decide what the agent may do

Probably not for

  • Training a model from scratch
  • An “automate everything” brief with no owner
