How we work
Three shapes, one team.
A scoped build with one number, one date and a defined deliverable.
Best for
A defined product you want designed, built and published.
- 01
Scope
We read the brief, ask what is missing, and send back one number and one date.
- 02
Design
Flows first, then screens, then a build-ready spec you sign off before code.
- 03
Build & review
Two-week increments. You run each one on a real device before the next starts.
- 04
Publish & support
We submit to the stores, handle review, and stay on for the releases after.
Ongoing development, maintenance, marketing or social, bought by the month.
Best for
A product that is live and has to keep moving.
- 01
Set the month
You buy a monthly capacity rather than a scope, and we agree what leads the list.
- 02
Ship continuously
The list is worked in two-week increments and released at the end of each one.
- 03
Re-cut the list
Each month we look at what shipped and what it changed, then reorder what is next.
Our developers join your existing team and work inside your process.
Best for
A team that has the product and needs mobile capacity.
- 01
Match
You tell us the stack and the seniority. You interview whoever we put forward.
- 02
Embed
They work in your repo, on your board, in your standup, reporting to your lead.
- 03
Scale up or down
Capacity changes a month at a time — no renegotiation and no new contract.
Equity and revenue-share partnerships are available in place of part of the fee. Ask in your brief.

FAQ
Questions we get.
Two ways. We can take a whole piece of the product off your hands — an app, a backend, a launch — or put engineers into your team, working in your repo, on your board, reporting to your lead.
Yes — any kind of app, in any stack. We read the code first, tell you plainly what state it is in, and carry on from where the last team stopped.
Systems that take repetitive work off your team: AI features inside your product, and workflows that connect the tools you already use so data moves and tasks run without anyone copying between them.
Yes. We prepare the listing, submit the build, answer review and handle a rejection if one comes back — then ship the updates that follow.
Yes — any kind of marketing. App Store optimization, paid campaigns, social media and content are run by the same team that built the product, so growth work and product work share one plan.
We stay on. Maintenance is free for a period after launch, and after that a monthly retainer keeps the product — and its marketing — moving.
You do. The code and the designs are yours, handed over in full.
By the shape of the engagement: a fixed price for a defined build, a monthly retainer for ongoing work, or a monthly rate per engineer for staff augmentation. Send a brief and you get a written proposal back.
