Investment is still high and it's likely to improve. I would argue that things are going to improve outside of the EU because it will free up the UK to deal more freely with Honk Kong / China and capital coming from Asia in general. There are a few fields where it's important to have a base in EU (eg. betting), but those companies already moved away from London to Malta and Cyprus. The reason investments arrive in London is largely because of the English language and ease of movement between USA and the UK. Wealth is trickling from overseas. You also have Ireland nearby to do dodgy tax deals, which comes in handy. I don't see Europe becoming more relevant for tech startups; it seems like they're trying to force the hand by making a sort of nationalised tech scene but I doubt they'll be as efficient as the market. The other nice place in Europe (but outside of the EU) for tech / banking is Zurich, in Switzerland.
