How we work

A month from first call to something you can use.

No discovery phase that bills for six weeks and produces a document. Scope, design, build, ship — with a demo at the end of every sprint.

  1. 01

    Week 1

    Scope

    We map the problem, agree what version one must do, and cut everything it does not. You leave the week with a written scope, a fixed price or rate, and a delivery date we are willing to be held to.

  2. 02

    Week 2-3

    Design

    Flows, screens, and data model in parallel. You review clickable work, not static mockups, so the arguments happen while changes are still cheap.

  3. 03

    Week 4+

    Build

    Two-week sprints with a demo at the end of each one. Staging updates continuously, so you can use the product long before it launches.

  4. 04

    Launch +30d

    Ship

    We deploy, watch the graphs, and fix what real traffic exposes. Thirty days of included support, then handover docs — or we keep going as your team.

The people

Know who is building with you.

The people in your Slack, on your calls, and in your Friday demos — introduced before the first commit.

Straight answers

The questions you are already thinking.

Not covered here? Ask us directly and you will get a real answer, not a brochure.

It is, if you buy on rate alone. We hire senior engineers with production experience, you interview every one before they join your project, and you can end the engagement with 30 days' notice if the work is not what we promised. Judge us on the first sprint, not on the pitch.

Our team works a shifted day to give you at least four hours of live overlap, every working day. Standups, demos, and escalations happen inside that window. The rest of our day runs on written updates, so you wake up to progress rather than questions.

Yes. The people writing the code are in your Slack and on your calls — there is no account manager relaying messages. You will also have a named engineering lead who owns delivery and sends a written update every week.

Adding engineers takes about two weeks, since we would rather ramp someone properly than drop a stranger into your sprint. Scaling down takes 30 days' notice, no penalty. We do not sell year-long minimums.

You do, from the first commit. We work in your repository under your accounts wherever possible, and the contract assigns all IP to you outright. If we hold infrastructure during the build, handover is part of the agreed scope, not an upsell.
