James Colby founded Polyphasic Developers in 2016 out of a straightforward belief: UK businesses deserve bespoke software built properly, by people they can actually talk to. What started as freelance work grew — through some difficult years, including James's recovery from cancer — into a full custom software development agency. In 2023, we incorporated as a Limited company.
Today we have development teams in the UK and Pakistan, project management based in the UK, and clients across three continents. We're still small enough that you'll deal with the same people throughout your project. For a quick overview of what we do, read what Polyphasic Developers is.
Some clients come to us with a clear product spec. Others just know something is broken or slow and need someone to figure out the right fix. We've handled both many times across a wide range of industries — fleet management, optical software, wellness tech, real estate, financial services, AI products, and local services.
We keep projects lean by design. One person you can call. Clear milestones. Work that ships in usable stages rather than in one big reveal at the end. That approach suits SMEs and founders well — businesses that need momentum, not process theatre.
A short description of the problem is enough to start a useful conversation. We can help you figure out the right approach — and whether we're the right people to do it.
