Quick Pitch

Spin is a dock-less bike-sharing service that lets users park anywhere so they can peddle without any hassle of bike locks. Bike sharing is a massive opportunity (Mobike raised $1 billion to tackle this market in China), and Spin is the first to launch location agnostic bikes in America. They expanded to Seattle in July and there's been so much demand that they're racing to keep up! 

In addition to the Rails backend, you could also work on the Go servers that communicate with each smart bike lock. 

Company Overview

Founded in San Francisco in 2016, Spin helps people move around cities by offering a convenient, affordable, and environmentally-friendly mode of last-mile transportation. Its fleet of GPS and solar panel-equipped orange-colored smart-bikes can be unlocked by scanning a QR code, and can be dropped off at any responsible parking spot at no cost to cities.

Spin co-founders Derrick Ko, Euwyn Poon and Zaizhuang Cheng met while at different Y Combinator companies, and the Spin team is comprised of engineers, designers, operators, lawyers and policy thinkers with experience from Lyft, Uber, Airbnb and other Silicon Valley companies.
