We got tired of the traffic and expensive Uber rides just to get around our neighborhood in San Francisco. So we came up with an idea: What if we had bikes all around town that you could pick up and drop off anywhere?

Bikeshare has been around for a while, but it always seemed silly to us that you could only ride to and from stations. And sometimes the stations got full. And God forbid if there wasn’t a station where your favorite snacks were sold. We started tinkering, and we were able to design internet-enabled bike locks that freed us from physical stations. 

And that’s what Spin is about. Making it easier for you to do you. To work, to play, to get outside. No more congestion, no more surge pricing, no more limitations. Just grab a bike and take a Spin.

We are a growing team of engineers, designers, operators, lawyers, and policy makers with experience from Lyft, Uber, Airbnb and numerous Y Combinator and Silicon Valley companies, and have raised a Series A financing round from a group of prominent Silicon Valley investors.


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.


Euwyn Poon, President

Euwyn grew up in Singapore and Vancouver prior to enrolling at Cornell and earning a CS degree at the age of 18, then obtaining a JD from Cornell Law School. Prior to starting Spin, he was a seed investor in over two dozen Y Combinator and Silicon Valley startups as the Managing Partner of Exponent.

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


Zaizhuang Cheng, CTO

Z focuses on weaving Spin's technology into the fabric of cities. Prior to Spin, he was the engineering lead on Disqus' consumer team, where he built products for hundreds of millions of users.

Z graduated with a degree in electrical engineering from Purdue, followed by a Masters of Management Science from Stanford University. He started a previous company with Derrick after Stanford, was part of the founding team at a B2B e-commerce company, and led teams of engineers at a defense contractor.
