Sojern

Leading vertical-specific digital marketing platform for the global travel industry, competing with both general-purpose DSPs and travel-focused marketing tools

Sojern is a leading digital marketing platform purpose-built for the travel industry, founded in 2007 and headquartered in San Francisco, California. The company leverages billions of traveler intent signals — including flight searches, hotel lookups, and booking behaviors — to help travel brands reach in-market travelers at the right moment across display, social, video, and connected TV channels. Its platform serves hotels, airlines, cruise lines, destinations, attractions, and car rental companies seeking to drive direct bookings and maximize marketing ROI. Sojern's core technology combines a proprietary traveler data graph with programmatic advertising capabilities, enabling highly targeted campaigns that go beyond traditional demographic targeting. The platform offers solutions spanning demand-side advertising, metasearch management, website personalization, and guest experience tools, making it a comprehensive marketing stack for travel brands of all sizes. The company has processed data from hundreds of millions of traveler profiles and works with thousands of travel marketers globally. In the AdTech ecosystem, Sojern occupies a distinctive niche as a vertical-specific demand-side platform (DSP) and data platform focused exclusively on travel. This specialization gives it a competitive edge over general-purpose DSPs when it comes to travel audience quality and campaign performance. The company has raised significant venture funding and expanded its product suite through acquisitions, including the purchase of VenueLytics to strengthen its hotel guest engagement capabilities. Sojern is widely regarded as one of the top travel marketing technology providers globally.
