At the 600-year-old Guildhall in the city of London, key players in a two-decade-old industry looking to remake finance are gathering.

Innovate Finance’s summit — part of U.K. Fintech Week — aims to showcase Britain’s financial technology sector and its global ambitions. Its profile has never been higher, with soaring demand from both customers and investors — even if the latter are proving a little harder to find than in the U.S.

Investments in U.K. fintech companies more than tripled to $11.6 billion last year, according to figures published by Innovate Finance, a trade body for the industry. That’s not including the billions that more traditional banks and tech giants are splashing out to upgrade everything from current account apps to emerging uses for blockchain.
