Why UK buyers choose us

A remote-first, US-headquartered senior team building bespoke software for UK businesses — GBP invoicing, a UK working-hours overlap and UK-GDPR-aware delivery, with the code yours from day one.

  • Remote-first senior engineers with a UK business-hours overlap window for stand-ups, demos and incident response
  • Invoiced in GBP (£) against a clear fixed-bid scope, so there are no surprise currency conversions on your purchase order
  • Delivery built to be UK-GDPR and ICO-aware: lawful-basis mapping, data-minimisation and a documented data-processing trail
  • Contracts run under a mutually agreed governing law, with a mutual NDA and the GitHub repository transferred to your organisation

We deliver with UK-GDPR and ICO expectations in mind — lawful-basis mapping, data-minimisation, subject-access readiness and a documented processing trail. We build to the controls your DPO or auditor specifies (we are not a law firm), and can scope UK or EU data residency where a workload requires it.

Process

How an engagement runs.

  1. 01

    Scope and platform decision

    We help you pick React Native versus native versus PWA based on the features list. Most projects land on React Native plus Expo with native modules for hardware integrations.

  2. 02

    Design and prototype

    Three to five weeks in Figma with interactive prototypes tested on real devices, not desktop. We design at 1x, 2x, and 3x density and check tap targets against Apple HIG.

  3. 03

    Build sprints

    Two-week sprints with TestFlight builds every Friday. Your team installs and uses the app before code review closes the sprint.

  4. 04

    Submission

    We handle App Store and Play Store submissions, write release notes, and respond to App Review rejections. First-submission rejection is normal, we have shipped through it.

  5. 05

    Launch and OTA window

    Soft launch in one geo, monitor crashes, push two to three OTA updates over the first month, then expand availability.
