Nauto Connected Car

Nauto was founded in February/March 2015 in Palo Alto, California by Stefan Heck, a former McKinsey senior partner and Stanford consulting professor (Ph.D. Cognitive Science, UCSD; B.S. Symbolic Systems, Stanford), together with co-founder Frederick Soo, who served as CTO/Co-Founder from 2015 to early 2017 before moving on (later joining AI chip startup Mythic). The company set out to build an AI-powered, camera-based system that could understand driver behavior and road context well enough to warn drivers before a collision occurred — explicitly framed by Heck as an attempt to 'beat the seatbelt' as a step-change safety technology, while also generating a large real-world driving dataset relevant to autonomous vehicle development. Nauto raised a $2.84M seed round in March 2015, followed by two Series A tranches in 2016 ($12M in April, led by Playground Global with DNX Ventures; $9M in October, from Toyota Research Institute, BMW i Ventures and Allianz X), reflecting early strategic interest from automakers and insurers. The company's defining raise was a $159M Series B in July 2017, co-led by a SoftBank Group Corp. subsidiary and Greylock Partners, with participation from BMW i Ventures, GM Ventures, Toyota AI Ventures, Allianz X, and existing investors Playground Global and DNX Ventures. Greylock partner Reid Hoffman and SoftBank's Shu Nyatta joined the board alongside Heck, automotive veteran Karen C. Francis, and Playground Global's Bruce Leak. This financing, one of the largest for a fleet-safety/computer-vision startup at the time, was explicitly framed around both improving fleet safety immediately and building a data platform to accelerate autonomous vehicle development.

Over the following years Nauto shifted its narrative from an 'onramp to autonomy' data platform toward a more focused enterprise fleet-safety and telematics business, becoming (per its own materials) trusted by 800+ fleets and later 1,000+ fleets worldwide, with customers such as bpx energy (BP's US onshore oil & gas unit), which reported an 89% reduction in distracted driving, 75% reduction in tailgating, and 62% reduction in at-fault collisions per million miles using Nauto. In June 2023 Stellantis Ventures made a strategic investment in Nauto as one of its first key investments, closing a Series C round (June 14-15, 2023; amount undisclosed) that brought Nauto's total funding to a cumulative $215M, per the company's own announcement. Employee headcount data (GetLatka, LinkedIn, Tracxn) shows a decline from a peak of roughly 173 employees in December 2021 to about 122-138 through 2022-2024 and roughly 130-137 through 2025-2026 — consistent with reports of cost discipline/contraction in the broader fleet-telematics/dashcam market (competing against well-capitalized rivals Samsara, Lytx, and Netradyne) even as the company continued to ship product (vulnerable-road-user detection, a consolidated telematics offering in October 2023, a 2025 CODiE Award, and independent VTTI-validated performance studies in 2024-2025). Estimated annual revenue (GetLatka) grew modestly from about $4.8M (2021) to $4.6M (2023) to $6.4M (2024) — small relative to total capital raised, underscoring the difficult unit economics and competitive pressure that reportedly pushed Nauto toward strategic alternatives.

The most significant recent development is a definitive merger agreement with Nexar Inc. (a dashcam/driving-data company backed by, among others, Mitsubishi and NextGear/Mobileye-adjacent investors), announced July 1, 2026, to create what the companies describe as 'the independent infrastructure platform for Physical AI' — combining Nauto's roughly 6-10 billion AI-processed driving miles and enterprise fleet-safety relationships with Nexar's larger real-world driving network (100M+ miles/month across 94% of US roads and 50+ countries) and its BADAS incident-prediction model. Under the terms, Nexar CEO Zach Greenberger will lead the combined company as CEO, while Nauto founder Stefan Heck will chair the combined board; BofA Securities advised Nauto and Fenwick & West served as legal counsel. The transaction remains subject to customary closing conditions and had not closed as of the most recent company communications (August 2026); Nauto states existing customers will continue to be served by the same teams and products through the transition. Crunchbase's company record already lists Nauto's status as 'Acquired by Nexar,' while Greylock's own portfolio page still lists Nauto's status as 'Active' as of the same period — indicating the deal had been announced but not yet finalized/reflected everywhere at the time of this research. Overall, Nauto's trajectory reflects a company that pioneered predictive, AI-based (rather than purely reactive) fleet dashcam safety technology and attracted top-tier strategic and financial backing (Greylock, SoftBank, BMW, GM, Toyota, Allianz, Stellantis, Playground Global, DNX Ventures), but which — after roughly a decade as an independent venture-backed company — is now combining with a larger, better-capitalized rival (Nexar) rather than continuing to scale alone, amid reported financial pressure and a maturing, consolidating fleet-safety/dashcam market.

Business model

B2B enterprise hardware-plus-SaaS — sells/leases an AI-enabled dual-facing dash cam device bundled with a cloud software subscription (safety analytics, coaching, telematics) to commercial fleet operators, insurers, and automakers.

Per-vehicle hardware plus recurring per-vehicle/per-driver SaaS subscription fees; also licenses driving data/AI models to automotive and insurance partners.
