imagesRideScout, a mobile app for ground transportation options, Tuesday announced its acquisition of Portland-based GlobeSherpa.

The financial terms of the acquisition were not disclosed.

Austin-based RideScout’s CEO and Founder Joseph Kopser discussed the acquisition with GlobeSherpa CEO and Co-Founder Nat Parker in a video that was livestreamed from Portland.

GlobeSherpa provides a mobile app that lets people book and pay for bus and train tickets in several major cities such as Portland, San Francisco and Chicago. The startup has raised $2.1 million from four investors in five rounds, according to its CrunchBase profile.

GlobeSherpa will operate as a wholly-owned subsidiary of Ridescout. Parker will continue to lead the company and its employees. Together, the companies will expand throughout North America and internationally.

RideScout, led by Kopser and COO Craig Cummings, has made its app available in 69 cities in North America. Moovel, the parent company of Car2go, bought RideScout in 2014.
