What do you need to build?

Launch a product, connect your systems or improve the software you already run. We can lead the build or work alongside your engineers.

New product development

From an initial idea to a working web or mobile product, with the engineering, infrastructure and launch handled together.

Hire us when

  • You need to turn a product idea into a first release.
  • An internal tool could remove manual work, but your engineers are busy keeping existing systems running.

You get

  • Web applications and the backend services they run on.
  • iOS and Android apps built with React Native.
  • Cloud infrastructure and a production deployment in your accounts.

Modernisation and integration

Connect the systems your business relies on, replace ageing software and deliver changes alongside your existing engineering team.

Hire us when

  • A platform needs replacing while the business continues to use it.
  • Your rollout has a deadline, and the internal team needs help delivering it.

You get

  • Integrations between existing platforms and new services.
  • Replacement components for systems that need updating.
  • Service and data migrations into the platform replacing them.

Ongoing product engineering

Keep a live product moving forward with new features, bug fixes and performance improvements across the app and the systems behind it.

Hire us when

  • Your product is live, but its list of fixes and improvements keeps growing.
  • Your product team needs more engineering capacity to deliver its roadmap.

You get

  • New features, fixes and dependency updates for web and mobile products.
  • React Native development for iOS and Android, with the backend work each release needs.
  • Performance improvements across the application and its services.

You see the work as it happens.

How we deliver
  • Working software to review every week.
  • Weekly spending tracked against your estimate.
  • Changes costed before the work starts.
  • Your code, accounts and documentation from day one.

Meet your engineering lead.
