Explore transformationBased at Bell Yard, London — at the heart of the UK's professional and technology ecosystem — Appinio brings international expertise to every project.
Appinio Limited is registered at 7 Bell Yard, London WC2A — one of London's most prestigious professional addresses. We work with clients across the UK and internationally, combining the reach of a London firm with the agility of a focused team.
We work in lean, focused sprints — shipping working software early and iterating based on real feedback. No bloated processes, no wasted time. Just clean delivery from an experienced, international team.
A clear, structured process that keeps you informed and delivers results every time.
We learn about your goals, users and constraints. Free, no-obligation — usually 45 minutes. We'll ask the right questions to understand what you actually need.
We produce a detailed technical proposal — scope, timeline, team, stack and pricing. Fixed-price or time-and-materials, depending on the project.
Agile sprints with weekly demos. You see working software early and can shape direction throughout. Transparent tracking, zero surprises.
We handle deployment, testing and go-live. Ongoing support packages available for monitoring, maintenance and future feature development.
"Appinio built our entire customer portal from scratch in 10 weeks — on time and on budget. The quality of the code and the UX is exceptional. A genuine pleasure to work with."
"We came to Appinio with a vague idea and left with a fully designed, working mobile app. Their team asked all the right questions and brought ideas we hadn't even considered."
"Engaged Appinio for a legacy system migration. Flawless execution — zero downtime, clean architecture and a team that really understood what we were trying to achieve long-term."
