The raise of Adyen made people aware...but the 1 Bn transaction of another Dutch Payment company called global collect last summer of 1 Bn+ seem to have happened without notice.
I chose Amsterdam as the next stop on the Fintech City Tour, primarily because of Adyen. When a Fintech Unicorn appears in a place that is not on most people’s radar screen, it seems like it is worth a visit. Another reason is that I spent a very enjoyable year working in Amsterdam as a young man and although this visit is on the digit express I hope to stroll down the Herengracht again on a future visit. I also see a lot of Bitcoin expertise in Holland. I first noted that Ethereum has some of their core developers in Holland and somebody pointed out that Bitpay has set up its European HQ in Amsterdam.
