But London & Capital insisted that as the British capital develops its reputation as a tech hub, fundraising will only get easier for London tech firms – as demonstrated by the growing size of the funding rounds.
Three British tech firms managed to raise over $50 million over the period, the research showed. Food-ordering site takeaway.com successfully completed a funding round of $102.7 million, high-end retailer farfetch.com raised $66 million and peer-to-peer lending network Funding Circle received $65 million in investment.
Other big fundraisers (which completed rounds of over $30 million) included cloud software company eCommera (now OrderDynamics), money transfer start-up WorldRemit and investment management service Nutmeg.

"Tech is blossoming and our reputation for innovation and discovery, allied with outstanding talent, is attracting record breaking levels of investment from around the globe," he said in a statement.
