Types of software we build for UK clients.
We build software that solves real business problems — from lean MVPs to complex enterprise platforms. These are the most common project types.
Web Applications
Custom web apps for internal use or customer-facing products. Dashboards, portals, SaaS tools, booking systems, reporting platforms. Built with React, Next.js, Vue and Node.js.
Mobile Applications
iOS and Android apps for UK businesses and consumers. Native apps in Swift or Kotlin. Cross-platform in React Native or Flutter. Combined web + mobile projects welcome.
Bespoke Software
When off-the-shelf products don't fit your process, we build from scratch. Workflow automation, regulatory compliance tools, custom CRMs, multi-tenant platforms and ERP integrations.
API & Backend Systems
Secure REST and GraphQL APIs. Microservices architecture. Integrations with third-party services — Stripe, Xero, Salesforce, Slack and more. Node.js, Python, .NET or Go.
MVP Development
Validate your idea without over-investing. We scope and build testable MVPs in 8–12 weeks. Launch with real users, learn fast, and invest in scale only when you've proved demand.
Cloud & DevOps
Cloud infrastructure on AWS, Azure or GCP. Docker, Kubernetes, CI/CD pipelines, automated testing and monitoring. Your software delivered reliably, with zero downtime deployments.

Do you work across the UK, not just London?
Yes. We're UK-registered (London) and remote-first — we serve clients in Manchester, Birmingham, Leeds, Bristol, Edinburgh and beyond. Location doesn't limit what we can deliver.
Can you work with our existing development team?

I only have an idea — is that enough to start?
Yes — most of our projects start as an idea. Our free consultation helps you turn it into a defined scope, realistic timeline and clear budget. No commitment needed to start talking.
