About Turnstone

Turnstone began in 2019 as an internal project between IDAX Data Solutions and the Seattle Department of Transportation. It spun out as an independent company in 2021, and now serves cities including Seattle, Denver, Santa Rosa, and Berkeley.

We built Turnstone because curb space is one of the most contested public resources a city manages, and the tools to manage it well have lagged far behind the problem. We've stayed self-funded and independent, focused on what each parking program actually needs, not on investor metrics.
