For web applications that already exist

We take over the applications other teams left behind.

If your web application is unstable, out of date, or the developer who built it has gone, you do not need a rebuild. You need someone senior to take it over, make it safe, bring it up to date and keep it moving — at a fixed price, starting with a five-day audit.

01Situations

Which one is yours?

01

Your developer or agency has gone.

The app runs, nobody knows how, and the roadmap is frozen.

We recover access, write down what is there and make it safe to change.

Start with the audit
02

Your app runs on old technology.

It still works, but parts of it no longer get updates, and every upgrade is postponed because nobody wants the risk.

We move it from legacy to modern in small, tested steps, without a big-bang rewrite.

See how migration works
03

You run an agency and need an engineering partner.

Overflow on new builds or existing apps, a stack you do not staff, or a client app you inherited.

We work under your brand, in your tools, in hours that overlap with yours.

Outsourcing for agencies
04

Your startup's product works. Is it ready?

It was built fast by a freelancer, an agency or AI tools, and now real users, investors or a first hire are coming.

We check it, fix what is risky and give you senior engineering cover before your first engineering hire.

02What we do

A specialist garage for the software you already have

Most software companies build new apps from scratch. We look after the ones that already exist: we check what is there, fix what is breaking, move it onto supported technology, keep it healthy every month and build what comes next. Every engagement starts with the audit, because we do not quote fixed prices on code we have not read.

03Process

How a takeover works

  1. Step 1 · 30 minutes, free

    A triage call

    You describe the situation; we tell you what we would check first and whether we are the right fit.

  2. Step 2 · 5 business days

    A five-day audit

    Read-only access to your code and environments. You receive the report and the plan whether or not you continue.

  3. Step 3 · 2–6 weeks

    A fixed-price sprint

    Fixed scope and price, 50% on signature and 50% on acceptance. All work in your repositories and accounts from day one.

04Why us

Why a senior-led company is the safer choice

  • The person on the call does the work.

    No account manager and no hand-off to a junior team.

  • Fixed prices, not hours.

    We use AI-assisted engineering to read code, make repetitive changes and draft tests, and keep that speed in the price instead of billing hours. Every change is reviewed by a person.

  • Nothing to hide.

    Our public work is on the Work page, our process is written down, and every price is agreed in writing before work starts.

Our hours, in your time zone

We work 03:30–12:30 UTC, Monday to Friday. In your time (UTC) that is 03:30–12:30. Outside these hours everything is async and in writing, with a reply by the next working day.

Scale: your time (UTC)

Live overlap with your working day: 09:00–12:30. That is the best time for calls.
