Why mobile matters in London
London is Europe's largest tech hub and home to the world's densest concentration of fintech companies, supported by the FCA's progressive regulatory sandbox. UK consumers are highly mobile-first, with over 90% of UK adults owning a smartphone, and London businesses face intense competition for digital-first customer attention.
