This is a newsletter about big bets, explored through conversations with the product leaders who worked on them. For this one, I chatted to Can Ulker, a former product manager at Booking.com, about a bet they took on building a product to offer package holidays. Founded in 1996 in Amsterdam, Booking.com has grown from a small Dutch startup to one of the world’s leading digital travel companies, and it’s famous for its data-driven approach to product development.
