Agents you can actually let run.
An agent that works in a demo and an agent you would trust with a customer record are different pieces of engineering. The difference is guardrails, evaluation and an audit trail — which is most of what we build.
Book a consultationWhat this looks like
Four things we are usually asked for. Most engagements combine two or three of them.
Tool-calling agents
Agents that plan a task, call your internal APIs and databases, and complete multi-step work without a human relaying each step.
Guardrails and permissions
Scoped credentials, action allow-lists, spend caps and human approval gates on anything irreversible.
Evaluation harnesses
A test suite of real tasks with graded outcomes, so you can tell whether a prompt or model change actually improved things.
Observability and audit
Every plan, tool call and result logged and searchable, so a wrong answer can be traced back to its cause.
How an engagement runs
The same four stages on every project, whether it runs six weeks or six months.
Discovery
A two-week sprint with your team to map the problem, audit the data, and work out whether this is worth building at all.
Scope and estimate
A written plan with what we will build, what we will not, the timeline, and what it costs. No deck, no retainer trap.
Build
Two-week iterations with a working demo at the end of each. You see progress in the product, not in a status report.
Handover
Documentation, a walkthrough, retraining and deploy scripts, and a support window while your team takes over.
What clients get out of it
Figures from real engagements. We will walk you through the full context on a call.
