Sojern

Sojern ingests anonymized search, booking, and browsing signals from a network of airline, hotel, and travel-booking partner websites. These data streams capture intent patterns — someone pricing a flight to Tokyo or browsing resort galleries — and the firm's engineering and data-science teams reconstruct that behavior into targetable audience segments. Sojern does not resell raw data; it activates the intelligence through its own media-buying platform.

Sojern does not manage pooled outside capital or function as a venture firm. It operates as a technology company whose primary business is performance-advertising software and managed services for travel-industry clients. As of 2026, the corporate entity has been folded into RateGain, a publicly listed travel-technology consolidator, which changes its governance but not its media-activation model.

The platform activates campaigns across display and native placements, social inventory on Facebook and Instagram, connected-TV and online video, paid search, metasearch engines such as Google Hotel Ads and TripAdvisor, and direct email and SMS. Sojern handles creative versioning, bidding logic, and cross-channel optimization rather than requiring clients to manage those channels separately.

Sojern markets the platform as an integrated software-and-services combination where campaign setup, audience strategy, and optimization are handled by its internal teams. The firm does not publicly offer a pure self-serve interface divorced from its account-management or strategy layers, which aligns with its positioning as a full-funnel marketing partner for hotel groups, destinations, and attractions.

RateGain now hosts Sojern's career listings and the two share corporate infrastructure, suggesting back-office functions and some go-to-market resources are merging. Sojern continues to operate its brand and platform separately in client-facing materials, but the integration places strategic decisions under RateGain's consolidated travel-technology umbrella.
