About
KAYAK is a travel metasearch engine founded in 2004 by Steve Hafner and Paul English, acquired by Booking Holdings (then Priceline Group) for $1.8B in 2013. Headquartered in Stamford, Connecticut, KAYAK aggregates flight, hotel, car rental, and vacation package results from hundreds of travel sites, enabling one-click comparison shopping. Its product suite includes KAYAK.com, the Momondo brand (acquired 2017), HotelsCombined, and a business travel management platform, KAYAK for Business.\n\nKAYAK's revenue model is primarily CPC (cost-per-click), charging airlines, OTAs, and hotels for qualified referrals rather than taking a booking commission. This metasearch model positions KAYAK as a neutral aggregator rather than a competing OTA, though it also offers direct booking through its platform in select categories. KAYAK for Business targets corporate travel managers with policy controls and expense integrations.\n\nAs a wholly owned subsidiary of Booking Holdings ($26.9B revenue FY2025), KAYAK does not report standalone financials. It remains one of the most visited travel websites globally, with over 300 million monthly searches across its brand portfolio. KAYAK's AI trip-planning features and integration with Booking.com inventory have strengthened its position as a one-stop travel research tool heading into 2026.

About

Trivago's brand is built on its iconic TV advertising campaigns across 55 countries.\n\nTrivago generates revenue through a CPC (cost-per-click) model, charging advertisers—primarily OTAs and hotel chains—for qualified hotel shopper referrals. Its referral auction system ranks advertiser bids alongside relevance signals to determine listing order. Trivago has invested in a hotel profile platform that allows hotel owners to manage their public-facing content and pricing directly.\n\nTrivago reported annual revenue of €485M (~$522M) in 2023. Expedia Group owns approximately 65% of Trivago. The company has undergone restructuring to reduce dependency on performance marketing and increase direct and organic traffic.
