Who Founded Kayak and When
Kayak was co-founded by Steve Hafner and Paul M. English in 2004 as a travel metasearch engine that aggregates fares from airlines, hotels, and car rental companies. The company launched its public-facing website in 2005 and later became a subsidiary of Booking Holdings, formerly known as Priceline Group. Steve Hafner, the kayak founder, previously co-founded Orbitz and served as Kayak's CEO for many years before transitioning to a board and advisory role. Paul M. English, another co-founder, went on to build other technology ventures and philanthropic initiatives after his involvement with Kayak. The company's early strategy focused on providing transparent price comparisons across multiple travel providers, a model that later influenced many other metasearch platforms.

Kayak's Acquisition by Booking Holdings and Leadership Structure
Booking Holdings acquired Kayak in 2005, and the company has since operated as a wholly owned subsidiary within the Booking Holdings portfolio alongside brands like Booking.com, Priceline, and Agoda. Under this structure, Kayak maintains its own brand identity while benefiting from Booking Holdings' global distribution and technology infrastructure. The kayak founder Steve Hafner has remained connected to the company through board memberships and advisory roles within the broader Booking Holdings ecosystem. Current leadership at Kayak includes executives responsible for product, engineering, and global operations who report into Booking Holdings' corporate structure. The acquisition allowed Kayak to scale its technology and data capabilities while maintaining a focused product experience for travelers searching flights, hotels, and rental cars. Additional details about Booking Holdings' acquisitions and corporate structure are available on the SEC filings page SEC official website.
Kayak's Public Market History and Current Financial Position
Before the acquisition, Kayak filed for an initial public offering but ultimately was acquired by Booking Holdings, so it has not traded as an independent public company on a stock exchange. As a subsidiary, Kayak's financial results are reported within Booking Holdings' consolidated earnings releases and SEC filings. Booking Holdings, the parent company, trades on the NASDAQ under the ticker symbol BKNG and is one of the largest online travel companies by market capitalization. The kayak founder's original vision of a comparison engine evolved into a core component of Booking Holdings' multi-brand travel portfolio. Investors interested in Kayak's performance can review Booking Holdings' quarterly and annual reports, which include segment data for the metasearch business.
