RideScout CEO Joseph Kopser speaks at the apps launch party at the 1776 shared office space.s launch party at the 1776 shared office space.

The RideScout app officially launched in D.C. last night in its 1776 tech startup headquarters. Mayor Vince Gray and former U.S. Chief Technology Officer Aneesh Chopra were in attendance to cheer on the new tool, which aggregates all of the nearby transportation options for users.

The app allows users to see the available partnered transportation modes around them, the prices, and how long it will take each mode to get them to their intended destination. RideScout’s dozen or so partners include Hailo, Capital BikeShare, car2go, and Alexandria Yellow Cab.

“This is something that is going to spread across D.C.,” Gray said in a brief speech at the launch party, right before he led the crowd of about 250 people in a “RideScout” chant with only moderate success.

A spokeswoman would not say how many users or how much total funding the app has, but she did say that the user base has grown 700 percent since July and has received more than $1 million in funding from friends and angel investors alone. RideScout has been available to download for a few months now in beta format.

The idea behind the app is to reduce traffic in cities, specifically cars with no passengers, which account for a good chunk of traffic.

“This is your call to action,” said Joseph Kopser, co-founder and CEO of RideScout, at the launch. “RideScout is for all Americans.”

Although D.C. is the first official launch city for the app, it plans to expand to other cities and is already available in places where its national ride providers are located.

According to a company release, D.C. Taxicab Commissioner Ron Linton and “several members of Congress” were also in attendance at last night’s party.
