Sonin
VerifiedReigate, Surrey app development agency founded in 2009 (trading as Big Orange Software Ltd). Award-winning iOS, Android and web specialist with clients including Caterpillar, The British Museum, Cambridge Audio, and Sheilas' Wheels.
About Sonin
Sonin was founded in 2009 in Reigate, Surrey and operates as Big Orange Software Ltd. With over 15 years of app development, the agency has carved a niche in IoT-enabled mobile products, SaaS platforms, and systems integration for ambitious UK and international brands. Notable client work spans healthcare (OpenAir Med), property (LandTech — handling 1 in 10 UK house sales), construction (Caterpillar), consumer goods (Schwartz, Sheilas' Wheels), and cultural institutions (The British Museum). Sonin maintains additional offices in Edinburgh and Paris and positions itself as a product partner rather than a build shop, offering product strategy, UX/UI design, app development, systems integration, and ongoing product support.
Why They Stand Out
Deep IoT and SaaS integration expertise sets Sonin apart from pure mobile shops — ideal for clients embedding mobile into hardware or enterprise platforms. 15+ years in Surrey with an Edinburgh office gives UK-wide credibility. Client roster from Caterpillar to The British Museum demonstrates versatility across complex, enterprise-grade briefs.
Ideal For
UK mid-market and enterprise organisations needing mobile products tightly integrated with IoT hardware, enterprise back-ends, or complex SaaS ecosystems. Industries including construction, property, healthcare, and manufacturing.
Potential Drawbacks (Honest Assessment)
Reigate HQ means London clients face a commute for in-person workshops. The $150-$199/hr rate band is among the higher end for regional UK agencies and may be hard to justify for projects with modest complexity. Smaller team size (50-249) could strain capacity during simultaneous large-scale engagements.
