A couple of newsletters ago, I mentioned how Booking.com is creating a new Fintech business unit that will grow to 400+ cross-functional fintech experts by the end of this year (you can find some of these jobs at the end of this newsletter). Daniel Marovitz leads this unit and has called the financial and payment challenge as the “last big mountain” and one that the company wants to climb. This week’s newsletter brings additional data points of the upside of fintech in the travel space and the hyper-activity taking place around IPOs, M&A and fundraising rounds.
