Summon

Seed Round in 2012
Summon is an on-demand transportation service operating in San Francisco that connects riders with taxis and vetted drivers through its mobile application. Users can easily request a ride by entering their credit or debit card information, which is used to pay for fares and tips after reaching their destination. The service emphasizes fair pricing for riders and transparent policies for drivers, enhancing the overall experience for both parties. Summon was inspired by a personal experience of its founder, who faced significant delays while waiting for public transportation, ultimately leading to the creation of a more efficient ride-hailing solution.
