Custom Development

Bespoke agents and applications built to your workflow: production-grade and yours to own.

Problem

Off-the-shelf tools don't fit how you actually operate. Your internal team is at capacity, and the last prototype is too fragile to touch. That's how AI work stalls: a promising build nobody can safely extend or put in front of customers. We build software to your real workflow, observable and eval-tested. We document it so it keeps shipping after we leave, instead of becoming a black box you're afraid to change.

What we build
  • Custom agents and agentic workflows
  • Internal tools and operational dashboards
  • APIs and backend services
  • Data and document processing pipelines
  • Eval suitesAn eval suite is a versioned set of test cases that measures whether outputs are good. and CI for AI behavior
Deliverables

Everything below transfers to you at handover. No retainer, no lock-in.

  • A deployed application running in your environment
  • Full source code and infrastructure-as-code
  • An eval and test suite wired into CI
  • ObservabilityObservability captures traces of every prompt, retrieval, tool call, and response for debugging. and alerting
  • Documentation and a working handover
Ownership terms

You own every line.#

Explicit handover terms, not fine print — this is what transfers to you when we're done.

  • All source code transfers to you at handover.
  • Infrastructure-as-code for the whole system transfers to you.
  • The eval suite and tests transfer to you.
  • Credentials and accounts we provision transfer to you.
  • Documentation and runbooks transfer to you.
  • No retainer required to keep it running.
  • No kill-switch, no vendor lock-in — operate and extend it without us.
Outcomes
  • Software that fits how you actually work, running in production
  • Quality you can measure: evals in CI tell you if a change made it better or worse, not a vibe
  • A readable codebase your team owns and extends. Every repo and credential transfers at handover
  • Faster iteration after launch, because the build was made to be maintained

Questions

Questions, answered.#

The questions we get asked most, answered plainly: no hedging, no marketing copy.

01 Who owns the code?

You do, outright. Every repository and credential transfers to you at handover, along with every piece of infrastructure we set up. There's no kill-switch and no retainer required to keep it running.

02 How do you prove the AI behaves?

We build an eval suite alongside the feature — a set of test cases with expected behavior that runs in CI on every change. You get a concrete, repeatable answer to "did this get better or worse," not a vibe.

03 Can our team maintain it after handover?

That's the design goal. We write for readability and document the non-obvious decisions. Wherever possible we use tooling your team already knows, so the codebase isn't a black box.

04 How fast do you ship a first slice?

We scope a thin, end-to-end vertical slice first, usually within the first couple of weeks, so you're validating real behavior early instead of waiting months for a big reveal.
