Custom app, MVP, and platform builds

Ship the real thing.
Not a prototype that stalls.

A senior-led London studio that designs and builds custom apps, MVPs, and platforms — from first scope to a launch you own outright. No juniors, no handoff to a team you never met. Then we stay on to grow it.

Proof, not promises

Products we built — and in one case, still run.

iOS app

Loopa

Our first client. A premium place-curation app — library, remixable loops, a taste-driven discovery feed. Built in React Native and shipped to TestFlight.

We own it

Live

sellyourboat.io

A yacht marketplace and white-label brokerage platform we built and still operate — CRM, email sequencing, and a Claude-powered AI layer running underneath.

Conversion

2 wks

busesforsale.com

A two-week audit and UX revamp built for conversion — rethinking the enquiry path on a live marketplace to turn interest into action.

What a build includes

One senior team, from the first sketch to a product in people's hands.

Product & scope thinking

We pin down what version one is — the core loop, the journeys that matter, and everything we're deliberately not building yet.

Design that ships

Interface and interaction designed against the real build, not a Figma file engineering has to reinterpret. What you approve is what goes live.

Real engineering

Production code in React Native or Next.js, on infrastructure that holds up. Clean, owned by you, built so the next feature isn't a rewrite.

Launch & grow

Live to the App Store, TestFlight, or Vercel — with the option to keep us on to grow it. We build the product, then stay to make it work.

How a build runs

Four stages. No black boxes.

Fix the scope

What version one is, what it's worth, and the shortest path to something real. Scope and price agreed before we start.

Design the product

The interface and core journeys, designed against the real build so what you sign off is what ships.

Build & launch

Production code, live to the App Store, TestFlight, or the web — tested and handed over clean.

Grow what shipped

Optional. We stay on to evolve the product as it meets real users. The part most studios skip.

Before the next step

The questions people usually ask first.

How much does a custom app or MVP cost?

Every build is fixed-price and scoped up front, so you know the number before any work starts. Where it lands depends on what version one needs to do — the pricing page covers the current ranges.

Do I own the code?

Yes, outright. Everything is handed over clean and owned by you — no lock-in, and no dependency on us to keep it running.

Do you build for iOS, web, or both?

Both. Mobile apps are built in React Native, web products in Next.js, and many builds ship across both from a shared foundation.

How long does a build take?

It's scoped in discovery before we commit. A focused MVP is usually a matter of weeks rather than months.

Can a build turn into an ongoing partnership?

Yes, and it often does. Build the stronger first version, then move into Embedded Partner once you need continuous refinement.

Next step

If it's worth building,
it's worth building once.

Premium done once is cheaper than cheap done twice. Tell us what you're building — one reply, from the person who'd actually run it. See pricing for where a build starts.
