According to vice president of global segments Olivier Grémillon, there’s still a sizable market out there for the online travel agency to capture, and it’s the company’s responsibility to get there.

Speaking at Phocuswright Europe earlier this month, Grémillon says for the business he’s in charge of, he’s measuring the size of opportunity for individual segments, for example homes or B&Bs, and prioritizing them with the goal of growing all of Booking.com’s accommodation offerings at scale.
