At the Global Business Travel Association’s annual conference in Boston, GroundLink, a global black car service, announced the introduction of Ride Now, an app-based service allowing customers to obtain a ride in 20 minutes or less.

The service, now available, expands the company’s footprint in metro Boston and substantially reduces lead times needed to book a scheduled ride to and from surrounding New England suburban areas. For every Boston Ride Now ride completed through Aug. 31, GroundLink will donate $5 to the Big Sister Association of Greater Boston.

“It is exciting to be announcing our increasingly popular Ride Now service here in Boston during the largest corporate travel convention in the country. We currently offer Ride Now in New York and Chicago, and just recently launched in Austin, Dallas and Houston. Boston is the latest city to join our growing number of Ride Now markets, as we continue to rapidly expand this service as the perfect complement to our scheduled service,” said Liz Carisone, chief executive officer, GroundLink. “While business travelers still prefer to schedule many of their rides, such as trips to the airport, they also want to have access to last-minute rides for that impromptu meeting or pick-up from the airport that they didn’t book in advance. Ride Now is the perfect solution for such instances. We are also extremely pleased to be giving back to the local Boston community through our partnership with the Big Sister Association of Greater Boston.”

For service, members open GroundLink’s mobile app, select the location to be picked up and dropped off then select Ride Now. Once booked, the customer will see their driver in real time and a price breakdown of the trip prior to booking; rates are locked in. Once the ride is in progress, customers can track their car and communicate directly with the driver.
