SaaS Development London is the SaaS engineering arm of UIDB Group. We have been building software products since 2014 — long enough to have learned from the mistakes that sink most SaaS projects, and long enough to have built the processes that prevent them.
Our team is based in London and has delivered over 150 SaaS products across industries including fintech, healthtech, edtech, field services, logistics, and B2B enterprise software. We are not generalists who dabble in SaaS — it is all we do.
What we actually do differently
The honest answer is: we push back. Most agencies tell clients what they want to hear. We would rather have a difficult conversation in week one than rebuild something in month four. That means telling you when your MVP scope is too large, when your architecture choice will hurt you at scale, or when the timeline you have in mind is not realistic.
We also write production-quality code from day one. There is no prototype-that-becomes-production here. Every project gets proper testing, CI/CD, and documentation — because the shortcuts you take in month one are the incidents you deal with in month six.
Part of UIDB Group
As part of UIDB Group, we have access to a wider pool of specialists including UX designers, mobile engineers, and data engineers when projects need them. You get a focused SaaS team with access to broader expertise when the project calls for it.
Honesty over comfort
We tell clients what they need to hear, not what they want to hear. If a plan has a flaw, we raise it early — not after it has cost you money.
Engineering quality
We write tested, documented, maintainable code. Not because it is easy, but because it is the only kind of code that holds up over time.
Ownership
Every engineer on your project treats it as their own. We do not create handoff problems by rotating people through your project every few weeks.
Transparency
You always know where your project stands. Weekly written updates, regular demos, and honest estimates — not dashboards full of green lights that hide red problems.
Our Team
Or founded UIDB with a background spanning full-stack development, software architecture, and product strategy. He has built and shipped software for high-tech companies across Israel and the UK — including platforms that now serve hundreds of thousands of users — and leads the technical and commercial direction of every engagement.
Arik leads software architecture across our SaaS development engagements, setting the technical direction that ensures every platform we build can scale cleanly. His 15 years of architecture experience spans cloud infrastructure, API design, and complex multi-tenant systems.
Amir oversees engineering quality across our SaaS projects. With 20+ years of full-stack experience, he has shipped web applications across dozens of industries — and his code is the kind that client engineering teams are genuinely happy to inherit.
