Streetline

What Streetline does

Streetline is a smart parking technology company founded in 2005 and headquartered in Foster City, California, that builds machine-learning-driven solutions to manage vehicle parking across on-street, off-street, and truck parking contexts. The company's core platform is the Open Inference Platform, an unsupervised machine-learning system trained on more than 720 million parking events that produces real-time parking availability data with and without dedicated sensing infrastructure. The technology stack combines a proprietary IoT sensor portfolio (95%+ validated accuracy), camera-based ParQ Vision computer vision (97%+ accuracy), and a smartphone-based Parking SDK for infrastructure-less sensing, making the platform technology-agnostic across vision, radar, lidar, and ground sensors.

Streetline monetizes primarily through long-term enterprise SaaS contracts with municipal governments and state departments of transportation, supplemented by API/SDK licensing to mobility and OEM partners and IoT hardware sales. Anchor customers include the Los Angeles Department of Transportation (LADOT, since 2009), Oakland, CA (since 2016), Redwood City, CA (since 2013), Arizona DOT, and Washington State DOT, with truck parking deployments now live in six states. The product portfolio spans the Parker consumer app, ParkerTruck for freight, ParkerMap for merchants, ParkSight analytics, ParkEdge self-publishing portal, Guided Enforcement (patented, 99.5% accuracy), FAST survey tool, and developer-facing Guidance API and Parking SDK.

Go-to-market is multi-motion: enterprise field sales targeting transportation departments, an API-first developer channel, and a product-led consumer app strategy. Streetline has raised approximately $53.7M across five funding rounds from 2006 to 2014, backed by Sutter Hill Ventures, True Ventures, Qualcomm Ventures, Fontinalis Partners, RockPort Capital, and Citi, and remains a privately held independent company with 51-100 employees.
