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.

What this includes

Deliverables, line by line.

  • Scoping doc that names the entry MVP and the SaaS roadmap behind it

  • Subscription billing via Stripe with plans, trials, and metering
  • Onboarding flow that gets a new account to first value
  • Admin tooling for support, impersonation, and account management
  • Transactional email via Resend and product analytics on activation
  • Marketing landing page to capture early signups
  • Prioritized backlog of cut scope, with source code in your GitHub org from day one
Process

How an engagement runs.

  1. 01

    One-job scoping

    Week one. We pin down the single thing the product must do for the first customer and push everything else to a backlog. The output is an MVP small enough to ship and big enough to matter, with the SaaS roadmap sketched behind it.

  2. 02

    Design the core flow

    We design the path a user takes from signup to value, including tenancy and billing touchpoints, and skip the screens that can wait. You approve a clickable flow before we write feature code.

  3. 03

    Build sprints

    Two-week sprints with a deployed build at the end of each. Multi-tenancy, auth, billing, and onboarding come online in priority order. You and your early customers click the real thing every Friday.

  4. 04

    Launch

    We ship to production with subscription billing and analytics live, a landing page to collect signups, and the instrumentation to tell you whether accounts actually activate.

  5. 05

    Read and grow

    We look at real usage with you and pull the next most valuable item off the roadmap. You decide whether to keep building depth, expand tenancy, or refine pricing, with data instead of a hunch.
