Our History

Spin is a venture-backed transportation company based in SOMA, San Francisco. Founded at the end of 2016 by three friends who wanted a better way to get around their hometown of San Francisco, Spin's first product reimagines bikeshare.

Spin's smart bikes are all around your city. Unlock it with a tap, leave it anywhere responsible, and pay for your ride seamlessly with your phone. Whether it's a work commute, a grocery run, or just drinks with friends, Spin gives you the freedom to do more.

Spin is backed by a group of investors including prominent Y Combinator alumni.


Derrick Ko, CEO

Derrick has spent over a decade in consumer technology, working on products ranging from marketplaces to transportation.

He was most recently a Product Manager on the Growth team at Lyft, who acquired his Y Combinator and True Ventures-backed startup. Prior to that, he was Team Lead at Pivotal Labs, spent time at Microsoft, and started a company right after college. A Boston native, Derrick grew up in New York City and graduated from Purdue University with a degree in computer engineering.

Upon obtaining his law degree, Euwyn was recruited by Simpson Thacher & Bartlett in New York City to join its M&A team that represented private equity clients including KKR and Blackstone. He left law to be the founding CTO of one of the first vacation rental startups, then was funded by Y Combinator, First Round Capital, Chris Sacca, Ron Conway and other Silicon Valley investors to launch an enterprise collaboration startup that turned into the First Round Network
