Prior to Kayak, travel search was fragmented and complex. Founded in 2004, the hospitality booking startup turned the experience for online travel bookings on its head with the launch of a single service that could quickly compare options across multiple airlines and hotel websites. With its forward-looking design and product thinking, Kayak put customers back in control of their booking experience. Today, the company’s desktop and mobile properties support millions of consumers and business travelers worldwide.

Accel funded Kayak in 2006, helping support the business’ European expansion. We also participated in an additional follow-on funding round before Kayak went public in July 2012. Five months later, Priceline (now Booking Holdings) acquired Kayak.
