From our own work: We built Pulse, a fitness membership and coaching platform concept with member accounts, programs and a progress dashboard, to show how app products should look and behave. Read the Pulse case study.
New builds and modernisation on current .NET
We build web applications, APIs and internal tools on current long-term-support versions of .NET and C#, and we modernise older .NET Framework systems step by step — moving one module at a time behind the same interface, so the business keeps running while the code underneath is replaced.
Fits the Microsoft stack you already pay for
Most .NET projects live next to Microsoft 365, Entra ID (Azure AD) sign-in, SQL Server and Azure. We integrate with what is already there instead of adding new vendors, and we set up automated builds, tests and deployments so releases stop being a weekend event.
Documented so you are never locked in
Every project ships with readable code, architecture notes and a handover, and the repository lives in your account. Any competent .NET team can pick it up after us.

Fixed scope, fixed price
A strategy call defines the scope; the quote doesn't move mid-project.

Frequently asked questions
Can you upgrade our old .NET Framework application?
Usually, yes. We assess what can be migrated as-is, what needs rewriting and what can be retired, then plan the move in stages so you are not betting the business on one big switch-over.
Do you work with Azure?
Yes. We deploy to Azure App Service, Azure Functions and Azure SQL, and also to AWS or Google Cloud if that suits your setup better.
How much does it cost?
Every .NET Development project is different, so we don't publish a price list. Answer a few questions in our quote builder and you'll get a personalised plan and estimate — compared with market prices and designed around your budget — in about 3 minutes.
Do I own what you build?
Yes. The code, content, accounts and data are yours. No lock-in — leave any time and we'll help you move.
