Yes. Uber and Lyft provide most of the rideshares in Seattle. These rideshare companies technically operate as transportation network companies (TNC). TNCs provide an online network for connecting riders with drivers but are not responsible for actually transporting the passengers. Instead, the passengers are connected via the transportation network to Seattle drivers who use their personal vehicles, and pay these drivers for transportation. Often the cost of using a driver through a TNC is less than the traditional cost of a taxicab.
