Trivago

Trivago is a hotel price comparison and metasearch platform founded in 2005 in Düsseldorf, Germany. Acquired by Expedia Group in 2012, Trivago went public on Nasdaq in 2016 in one of Germany's largest tech IPOs of that year. The platform allows travelers to compare hotel prices across 180+ OTAs and booking sites in real time, covering over 5 million hotels, apartments, and alternative accommodations worldwide. 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. As of 2025, Trivago operates in 55 countries and 33 languages, with mobile apps accounting for a growing share of its qualified referral traffic.
