Polyphasic Developers is a UK software development agency, founded in 2016 and based in Lincoln. We build custom software, web apps, mobile apps, internal tools, and modern websites for businesses that have a real problem they need solving — not a template they need filling.
The simplest version: if you need something built, something old replaced, or a manual process automated, we're the people to talk to.
Depending on the project, that might be a bespoke web app, a mobile product on iOS and Android, an internal dashboard that replaces a spreadsheet-based process, a modern website that finally reflects how good the company actually is, or an AI feature built into an existing product.
We don't have a fixed style or a preferred technology stack. We figure out what the problem needs and build that.
Some clients arrive with a detailed brief. Others just know something is slow, outdated, or getting in the way. Both are completely fine starting points — figuring out the right approach is part of what we do.
We work well with businesses that value directness: no fluff, no scope creep left unexplained, no disappearing after launch.
"Most of the work sits in one of three buckets: something new needs building, something old needs replacing, or something manual needs automating. That's it. That's the agency."
