It's become harder for tech startup investors to raise money for their funds in the wake of Brexit. That's partly because of the two years of economic uncertainty that followed the vote. Two British startup investors, Ali Mitchell and Ben Tompkins, told Business Insider how Brexit stymied their plans to launch a European fund. They say the UK's burgeoning tech industry will adapt, but will be poorer for the uncertainty and dropoff in international talent. It's been more than two years since the UK voted to leave the European Union in June 2016.
