Car-sharing service Lyft has acquired Hitch, a startup in the mobile app-enabled car-pooling business, to integrate the service with its own shared rides business that it set up last month. “Similar to Lyft, Hitch has always believed the shared rides experience is inherently social, and we’re excited that they’re joining the team to accelerate this movement together,” Lyft wrote in a blog post Monday. The financial terms of the deal were not disclosed.
