Britain's fintech, artificial intelligence, and genetics startups have been going great guns recently, but Brexit has killed their momentum, according to a London startup CEO who is now considering whether he should open up additional offices outside the UK. Damian Kimmelman, CEO and founder of business information platform DueDil, told Business Insider: "I think the UK has three massive centres of excellence. "Those aren't going to go away very quickly but the wind has been knocked out of their sails." Companies like TransferWise, DeepMind, and Sophia Genetics have helped the UK to build a reputation as one of Europe's leading technology hubs. Kimmelman added: "In order to do something that really stimulates the tech economy, we have to look at this [Brexit] as an opportunity." The entrepreneur believes the UK should "be bold" and rip out the old financial services infrastructure before introducing a new one. "Use technologies such as blockchain and make that more pervasive," he said. "Other countries won't have the goal to take such audacious measures.
