Post Brexit has caused investors to question London's ability to maintain it's stance as one of the leading global fintech hubs. The result - neighboring European cities are flying in to London to basically "court" investors and financial firms, trying to convince them they they should be  next to carry the "fintech crown". Some think Amsterdam, Some Berlin some Paris, Some think Dublin may be the most eligible city to wear the crown, as many large tech companies have their HQ situated there, but without a strong financial industry it's hard to see how that will play out.
