About Spin

Spin operates electric scooters in cities and campuses nationwide, bringing sustainable last-mile mobility solutions to diverse communities. Recognized for its consistent cooperation and collaboration with cities, Spin partners closely with transportation planners, elected officials, community groups, and university administrators to bring stationless mobility options to streets in a responsible and carefully orchestrated manner.

Based in San Francisco, Spin is a diverse team of engineers, designers, urban planners, policymakers, lawyers and operators with experience from Y Combinator, Lyft, Uber, local and federal government, and the transportation advocacy world. Spin was known for launching the first stationless mobility program in Seattle, and has since expanded to become the exclusive electric scooter partner in mid-sized cities like Coral Gables, Florida and Lexington, Kentucky, and one of a few permitted scooter operators in large cities like Denver, Detroit, and Washington, D.C. The team embeds in cities and neighborhoods to understand their specific transportation needs, and hires locally from the community.

Spin is expanding quickly and looking for top-tier talent to help us bring affordable and accessible transportation options to cities and define what future safe streets will look like.
