Sonatus

Sonatus, Inc. is a Sunnyvale, California automotive software company, founded in 2018, that builds cloud-to-edge vehicle AI software for software-defined vehicles (SDVs). Its Fastlane platform pairs in-vehicle Fastlane Edge software with Fastlane Collector for dynamic, policy-driven vehicle data collection, Fastlane Insight for cloud-side analysis, and Fastlane Copilot for quick-start integration, alongside the Sonatus Automator vehicle-automation product. Sonatus states its technology is deployed in more than eight million vehicles worldwide, and it is backed by Hyundai Motor Group, Kia, LG, Marvell, NEC, Foxconn and Translink Capital. Sonatus sells to vehicle OEMs and tier-one suppliers rather than to individual developers: it markets an SDK comprising Sonatus Automator, APIs and documentation, but that developer surface is delivered to contracted OEM customers and is not published on any public developer portal.

Sonatus is profiled on the APIs.io network. Tagged areas include Company, Automotive, Software Defined Vehicle, Vehicle Data, and Connected Vehicles.

Sonatus’ developer surface includes engineering blog, support, and 13 more developer resources.

    Archive, while the public www.sonatus.com sitemap index contains no developer, docs or API section at all; the SDK and
