services / ai / custom-harness
Custom AI harnesses you can rely on.
A model alone is not a product. We build the harness around it: tools, permissions, guardrails, evaluations and observability, so agents do real work safely.
✦ Ready for the AI era. Agents are only as good as their harness and their data. We build both.

what we build
Custom harness, built for your company
- Tool and data access scoped to the task
- Guardrails, permissions and human-in-the-loop approvals
- Evaluations that catch regressions before users do
- Observability: logs, costs and quality over time

use cases
Where it pays off
Analyst agents
Agents that query your warehouse and answer business questions.
Operations agents
Automate repetitive workflows with approvals where it matters.
Support agents
Draft and triage with your knowledge and tools.
Internal tools
Custom copilots for your team inside the tools they use.
in practice
What working with a custom AI harness looks like
How it works
- A harness is the system around the model: instructions, tools, memory, permissions and the loop that runs them
- We give agents controlled access to your data and tools, such as your warehouse, analytics and internal systems
- Guardrails, approvals and logging make behaviour auditable
- The harness stays model-agnostic, so you can switch between labs as models improve
Problems we fix most often
- Agents given too much access, or too little to be useful
- No logging, so nobody knows what the agent did
- Prompts and tools tied to a single model
- Prototypes that never become reliable workflows
where it fits / A custom harness is the right step when off-the-shelf assistants cannot reach your data or follow your process. We build, test and hand it over, or run it for you.
faq
Frequently asked questions
What is an AI harness?
A harness is everything around a model that makes it useful and safe: tools, data access, permissions, guardrails, evaluations and monitoring.
Why not just use a model directly?
A model alone cannot reliably act in your systems. The harness decides what it can do, what it can touch and how you know it worked.
How do you keep agents safe?
Scoped permissions, human approval for sensitive actions, redaction of sensitive data and logging of every call.
How do you test an agent?
We build evaluation suites from real cases and run them on every change, so regressions are caught before users see them.
Can agents work with our data warehouse?
Yes. We give agents read-only, scoped access to governed data, ideally through your semantic layer.
Which models and frameworks do you use?
We are model-agnostic and work with all the major labs, choosing what fits the task, cost and latency needs.
