About us: At Booking.com, data drives our decisions. Technology is at our core. And innovation is everywhere. But our company is more than datasets, lines of code or A/B tests. We’re the thrill of the first night in a new place. The excitement of the next morning. The friends you encounter. The journeys you take. The sights you see. And the memories you make. Through our products, partners and people, we make it easier for everyone to experience the world.

Our new FinTech business unit - with teams in Amsterdam, Shanghai and Bangalore - develops new products and drives innovation to help us continue removing financial friction from the travel process. That makes buying and selling travel-related products and services simpler for both travelers and partners.
