01
PRACTICE — A

Direct to the model.

We integrate against the LLM API the same way we integrate against Postgres. No agent frameworks, no orchestration vendors, no migrations every six months.

02
PRACTICE — B

Senior, all the way down.

Every line of code on your project is written by an engineer who has shipped before. There is no junior team behind the curtain, no staffing pyramid.

03
PRACTICE — C

Eight weeks, then yours.

On day fifty-six you own the code, the prompts, the evals, and a runbook your team can extend. We do not host black boxes that hold your business hostage.

Runbook + pairing

A week of pairing with your team. We leave a system your engineers can extend, not a binary they can't.

pairing90-day warranty

Yes—forty-seven times so far. The trick is that we scope the smallest valuable thing in week one, then defer everything else to the runbook. We will turn down work that we can't scope into eight weeks.

Less surface area, fewer migrations, lower bills. We integrate against the LLM API the same way we integrate against Postgres—it's a tool, not a platform. Our clients keep that bet for years.

You own the code, the prompts, the evals, and the runbook on day one. There is no license, no lock-in, and no retainer that bills past cutover.

Two senior engineers, named, on the contract. There is no junior team behind the curtain. The people you meet on day one are the people writing every line.

We carry a 90-day warranty. If a regression ships from our code, we fix it on our dime—no retainer, no rebill.

Bring a real problem.
We'll bring code on day one.
