Mobile app developer in London
We're Built By Unicorns — an app development team with ex-Amazon, AWS-certified engineering behind it, building custom iOS, Android and web apps for startups and established businesses in London. London briefs skew towards platform and product work — customer portals, internal tools that carry real transaction volume, data pipelines, AI features grounded in a company’s own content — and towards teams who want an engineer in the room during the decision, not a proposal a fortnight later. Our team has shipped in exactly these environments: enterprise media, ticketing at national scale, financial services and news publishing.
App development for London businesses
London is where the ambitious engagements come from: venture-backed startups needing a technical co-pilot, and established firms in finance, media and professional services that need custom applications rather than a brochure site. It is also the market where the cost of a wrong architectural decision is highest, because the rebuild competes with a roadmap that cannot wait.
We are an hour from central London and happy to be there for kickoff, workshops and the sessions where being in the room changes the outcome. Everything else runs remotely on a shared board, because two people in a meeting room is rarely the best use of a build week.
