Every great system begins with a question, not an answer.

We spend time understanding the problem before writing a single line of code. Strategy first, then architecture, then execution.

Interactive — Try It Yourself

Design a system.
Watch it hold — or melt.

A tiny version of what we do every day. Add components, then wire them up — drag from a node's orange dot onto another node (or tap one, then the other). Click a wire to cut it. Crank the traffic and see if your architecture survives.

Enjoy designing systems? So do we — it's the day job. Tell us about yours.

U85 Tech was founded on a simple conviction: technology should serve the business, not the other way around. Based in London, we partner with organisations ranging from early-stage startups to established enterprises, bringing the same rigour and care to every engagement.

"We don't just write code — we build systems that outlast the teams who made them."

Our expertise spans the full stack — from pixel-perfect frontends to battle-tested backend services, from Kubernetes orchestration to data pipeline architecture. We've migrated databases at 3am, debugged race conditions in production, and designed systems that handle traffic spikes without breaking a sweat.

Every project teaches us something. After a decade of shipping software, we've learned that the best architectures are the simplest ones that work, and the best teams are the ones that communicate well. We bring both to every engagement.

Let's build
something remarkable

Whether you're launching a new product, scaling your infrastructure, or untangling a legacy system — we'd love to hear about it.
