What Turnstone does
Turnstone (Turnstone Data Inc.) is a Seattle-based software company that operates a cloud-delivered parking analytics platform for municipal parking programs across North America. The company's Curb Insights Platform ingests structured data from existing pay stations, mobile payment apps, LPR systems, PARCS equipment, permits, and policy configurations, then applies behavioral modeling to build a digital twin of a city's parking program. The model produces continuous occupancy estimates — validated at 86-89% accuracy against manual ground-truth counts — that capture the unpaid, underpaid, and overstaying vehicles representing up to 38% of real curb demand, which payment data alone misses. Output is delivered through four integrated modules (Dashboard, Analysis, Reporting, Inventory) and three subscription tiers (Baseline, Core, Advanced), with pricing scaled per managed space and foundational deployments for mid-sized programs typically starting at $15K-$50K annually.
Turnstone sells directly to municipal parking programs through an enterprise field-sales motion with demo-led conversion and supports sole-source procurement. Its named municipal customers include Seattle, Denver, Santa Rosa, Berkeley, and Boston, with documented outcomes such as $1.1M added to Santa Rosa's Parking Fund, a 51% revenue increase in one Seattle downtown curb area, and a 90% reduction in manual data collection burden in the Boston pilot. The company is privately held, self-funded, and operates with 1-10 employees; its leadership includes CEO Cole Jaillet (previously VP of Product at Passport), CTO Jeremy Debate (previously CTO of Anthro AI), and co-founder Scott Lee (founder of the predecessor IDAX Data Solutions). Infrastructure is hosted on AWS, with documented SOC 2 Type 2, ISO 27001, GDPR, and CCPA compliance posture, and the platform is architected to support deployment in a Canadian AWS region on demand.

Turnstone competitors and assessment
Company assessmentBroad incumbents
- Passport: Leading mobile payment and parking management platform serving 800+ municipalities; Turnstone integrates with Passport as a data source but Passport could also extend into occupancy analytics, making it both a partner and a competitive incumbent in the municipal parking software stack.
- SKIDATA: Global provider of access and revenue control systems for parking, mountain, and leisure facilities; Turnstone ingests SKIDATA PARCS data and overlaps in the municipal parking analytics space as a broader incumbent.
- INRIX: Transportation and mobility analytics provider with parking and curb products; competes broadly with Turnstone in city-grade mobility data and parking intelligence, though at a much larger scale and broader scope.
- PayByPhone: Large mobile parking payment provider across North America and Europe; serves as a data source for Turnstone and represents the type of incumbent that could bundle analytics into its existing municipal relationships.
- Flowbird: Global parking meter and transport technology vendor; Turnstone integrates with Flowbird pay stations for data ingestion, but Flowbird's broader portfolio puts it in incumbent position across the municipal parking stack.
- IPS Group: Smart parking meter manufacturer and services provider for municipalities; Turnstone ingests IPS Group meter data, and IPS represents a potential competitor with deep existing hardware relationships at city level.
- ParkMobile (by Arrive): Major North American mobile parking payment app owned by Arrive (formerly EasyPark); Turnstone ingests ParkMobile data and competes indirectly by offering the occupancy analytics layer that sits on top of payment transactions ParkMobile generates.
Direct peers
- Streetline: Smart parking sensor and analytics provider for municipalities; directly overlaps with Turnstone's occupancy and guidance use cases, though Streetline historically relies on hardware deployments versus Turnstone's hardware-free modeling approach.
Emerging players
- Curb Mobility: Curb management and curb API platform focused on digitizing the urban curb; overlaps with Turnstone on CDS-compliant curb data and represents an emerging competitor in the same municipal vertical.
- SenSen Networks: AI-based video and sensor analytics provider with a 2025 partnership with Turnstone for curb data; partially overlapping technology stack and a partner that could evolve into a more direct competitor as the partnership matures.
