About London

Software Development for London's World-Leading Tech & Finance Ecosystem

London is the UK's undisputed technology capital, home to over 80,000 tech companies and generating more venture-capital investment than any other European city. The East London Tech City — 'Silicon Roundabout' — in Shoreditch remains a startup hotspot, while established tech giants cluster around King's Cross (Google), Battersea (Apple), and Canary Wharf. The city's financial-services sector is the world's largest outside New York, and its creative industries contribute over £50 billion to the UK economy. TfL's open-data initiatives and the Mayor's Smart London programme create a rich ecosystem for civic-tech innovation, and London's 40-plus universities ensure a continuous supply of graduate talent across every discipline.
