Traxo has landed another sizeble investment round – this time a Series B injection led by TripAdvisor to the tune of $5.2 million.

The user review giant joins existing backers Thayer Ventures, Advantage Capital Partners and Silver Creek Ventures, as well as another new participant Aristos Ventures.

The Texas, US-based company is a best known as a data aggregation system for travel agencies, travel content providers and online service operators to capture off-platform bookings.

Also working via a white label service, Traxo handles policy compliance and travel spend tracking for travel management companies and corporations.

Traxo last landed an investment round in September 2013 when it secured a Series A worth $4.2 million. It took a seed round of $1.5 million a year earlier.

The company, which counts the likes of Lufthansa, Cornerstone and SAP on its customer base, was founded in 2008 by ex-Travelocity business development chief, Andres Fabris.

The new investment will give TripAdvisor a seat on the board of directors.

TripAdvisor senior vice president of global products, Adam Medros, says:

“Traxo’s foundational mission – to make traveling easier by facilitating the seamless flow of critical travel data – aligns with TripAdvisor’s overall focus on helping travelers experience a better start-to-finish trip.

“As a part of this investment, TripAdvisor believes our resources and knowledge can further scale Traxo’s ability to help more travelers have a seamless journey.”

Fabris says the new relationship with TripAdvisor, with its “tremendous global reach” and expertise, will help Traxo enhance its data services into 2017.
