Engineers make the calls.
Agents run the stages.
CustomLabs exists because we kept watching the same story: the RAGRetrieval-Augmented Generation (RAG) retrieves relevant passages at query time and feeds them into an LLM's context. demo that lied and the notebook that never shipped. Money went out and momentum went with it. Nothing ran in production. That's the gap we exist to close.
We work the other way. Senior engineers embed with your team and write the spec with you. Within weeks, a working, eval-tested system runs in your environment. We bring the infrastructure and the evals. You bring the domain knowledge and the data. You make the decisions only you can make. You own every line we ship.
We take on a handful of engagements at a time. The people you meet in the brief do the work. The section below shows how they work with our agent fleet.
Engage the studio →- 01
Build to ship.
Every project leaves you with a system running in production.
- 02
Boring infrastructure wins.
We use models like contractors use power tools. The interesting work is the system around them.
- 03
Eval-driven development.
If we can't measure it, we don't claim it. Every release rides on a test suite that mirrors the work.
- 04
Hand it back, properly.
Documented, observable, owned by you. You can run and extend it on your own.
How a brief becomes shipped code. #
- Write the brief with you.
- Make the calls that need a person.
- Answer the questions an agent stops to ask.
- Check the deployed result.
- 1 Plan gives a plan.
- 2 Code gives a diff and an open request.
- 3 Review gives a verdict.
- 4 Merge gives a merged change.
- 5 Verify gives a pass, or the work goes back.
This site is the proof. 203 tasks merged here in 109 days. 12 defects caught and written down.

You own every line.#
Explicit handover terms — 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 suiteAn eval suite is a versioned set of test cases that measures whether outputs are good. 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.
- You can operate and extend the system without us.
