Hire AI developers who have shipped to production

Most AI developers for hire have built a demo. Far fewer have kept a system running for real users after the demo, which is where the hard problems live: retrieval that leaks documents, agents that act on stale data, latency that creeps up, bills that stop being predictable. Our engineers work on that side of the line. You get a senior team that designs, builds and hands over, in your repositories and your cloud accounts, with the evaluation set that lets you change it later.

Who this is for

  • - A product team adding an AI feature to an existing SaaS product and needing people who can work inside a real codebase, not alongside it.
  • - A company whose first AI pilot stalled and needs engineers who can say why, fix it, and get it to production.
  • - A founder or CTO who needs a working system in weeks and wants to own the result rather than rent it.
  • - An enterprise team that needs senior AI engineering capacity for a defined project without a long hiring cycle.

What you get

  • - A named senior engineer leading the work, with the founder reviewing architecture decisions.
  • - The system in your repositories and cloud accounts from day one, with your team able to see every commit.
  • - An evaluation set built before the model work starts, so quality is measured, not asserted.
  • - Cost and latency budgets agreed in writing and reported against.
  • - A handover that includes documentation, runbooks and a working session with whoever maintains it next.
Cost

What it costs

There is no honest fixed price before discovery, and anyone who gives you one is guessing. What we can say in writing after two weeks: the build cost, the running cost per month at your expected volume, and what moves each. The build is driven by how many systems the work must touch and how strict the accuracy, latency and compliance bars are. The running cost is model calls plus infrastructure, and it can differ by ten times depending on the choices made in week one. How we price AI work.

Timeline

How long it takes

Discovery, two weeks: we map the problem, the systems involved and the success criteria, and put the numbers in writing. Pilot, four to six weeks: one capability, live, on a slice of real traffic, measured against those criteria. Then production hardening and scale out. Each stage is a separate agreement with no minimum commitment, so you can stop after discovery with a plan you own. How we work.

Ownership

What you own afterwards

Everything. The code, the prompts, the evaluation set, the infrastructure configuration and the documentation, in your accounts, under your name. We do not hold anything hostage and we do not license our own platform to you. The evaluation set matters most: it is the thing that lets your team, or any other team, change the system later without breaking it. The deliverables clause.

Proof

A real one

A US automotive SaaS product had an AI assistant that missed intent and took up to 30 seconds to answer over 120 GB of documents. We rebuilt the retrieval, permissions and routing around the model. First token in under three seconds in typical interactions, about 98 percent accuracy in the client’s evaluated use cases, and roughly 30 percent lower operating cost.

Questions buyers ask

How much does it cost to hire AI developers?

It depends on scope, and anyone who gives you a number before discovery is guessing. After a two week discovery we put the build cost and the monthly running cost in writing, with what moves each. The build is driven by how many systems the work must touch and how strict the accuracy, latency and compliance bars are. The running cost is model calls plus infrastructure and can differ by ten times depending on choices made in week one.

Do we own the code if we hire your AI developers?

Yes, all of it. Code, prompts, evaluation set, infrastructure configuration and documentation, in your accounts under your name. We do not license a platform to you and nothing is held back at handover.

How quickly can hired AI developers start?

Discovery can usually start within two weeks of agreeing scope. The pilot that follows runs four to six weeks on real traffic. Each stage is a separate agreement, so you can stop after discovery with a written plan you own.

What is the difference between hiring AI developers and using an AI platform?

A platform is right when your task fits its shape and volume is modest; it is cheaper to start and more expensive to change. Hired developers are right when the system must act on your own data and systems, when the logic does not fit a template, or when you need to own the result. Our build versus buy article works through the arithmetic.
