01 / 06 · What we build

Digital products for your industry — with or without AI.

From public websites to internal platforms: we scope the smallest useful version, then ship. AI is one tool in the kit, not the only one.

02 / 06 · How it works

From idea to something real in seven days.

Fixed scope, fixed timeline, fixed price. You get a working prototype on Day 7 — site, tool, or system — keep it, scale it, or kill it.

See the full process
  1. Day 01
    Step 01

    Scope

    60-min call. We agree on the smallest useful version of your idea. Out goes a one-pager.

  2. Day 02—03
    Step 02

    Build

    Stack chosen, repo set up, core loop running. You get a daily Loom.

  3. Day 04—06
    Step 03

    Iterate

    You try it. We sharpen. Edge cases handled. Evals where they matter.

  4. Day 07
    Step 04

    Ship

    Hosted, documented, demoable. Either we stop here or roll into Day 30.

The Fuel Depot

Full-stack fuel delivery & operations platform.

Outcome

Production-ready monorepo shipped for a real fuel delivery company. Orders, invoices, and live tracking now live in one app — and the team stopped reconciling on paper.

06 / 07 · FAQ

Quick answers.

Anything not answered here? Send a note via the intake form.

01Can you really ship a working prototype in 7 days?

Yes — when scope is sharp. Day 1 is a working session where we cut your idea down to the smallest useful version (site, tool, or AI workflow). If we cannot ship that in 7 days, we tell you on Day 1 and refund anything paid.

02Who owns the code and the model?

You do. Full source code, prompts, evals, and weights (where applicable) are handed to you on Day 7. No lock-in.

03What if the prototype does not work?

If we cannot deliver something working by Day 7, you get a full refund. We have not had to do this yet.

04Do I need a technical background to work with you?

No. You bring the problem and domain knowledge. We bring engineering, product judgment, and — when it helps — AI.

05Do you work with individuals, or only companies?

Both. Founders, operators, creators, and small teams all get the same playbook and the same flat pricing.

06What stack do you use?

Whatever fits — typically Next.js / TypeScript / Python / FastAPI / Postgres / a vector DB. We pick during scoping. No fashion projects.

07Can you sign an NDA?

Yes. Mutual NDA before Day 1 is fine, just ask on the intake form.

08Do you offer ongoing support after Day 30?

Yes. Custom tier covers ongoing improvements, monitoring, and feature work on a monthly retainer.
