The company that turned ordinary dashcams into a live, machine-readable map of the physical world.
Most people who buy a Nexar dashcam want one simple thing: proof, in case something goes wrong on the road. What they may not realize is that their commute is quietly contributing to one of the largest independent views of the physical world ever assembled.
Nexar Inc., founded in 2015 by Eran Shir and Bruno Fernandez-Ruiz, sells LTE-connected dashcams that record in up to 4K, back footage up to the cloud automatically, and run an AI companion app that warns drivers of hazards in real time. That is the visible half of the business. The half that matters to city planners, insurers and autonomous-vehicle engineers is CityStream - a platform that aggregates trillions of anonymized images from the dashcam network into a continuously updated, ground-level picture of streets.
The pitch to a city is blunt: minute-by-minute visibility of every road, without sending out a single survey truck. Where infrastructure change used to be discovered weeks late, Nexar's network reports it as the cars already driving those roads pass by. Road work zones, faded lane lines, shifting curb space, new signage - the unglamorous details that trip up both maintenance crews and self-driving systems - become data you can query.
From a $4M seed round the company grew into roughly $150M raised across five rounds, drawing in Alibaba's innovation arm, Samsung NEXT, insurers Nationwide and State Farm Ventures, and specialist funds from Corner Ventures to Qumra Capital. In July 2026 it agreed to merge with Nauto to form what the two companies call an independent infrastructure platform for physical AI.
That phrase - physical AI - is the thesis. The digital world has been mapped, indexed and modeled for two decades. The physical world, the one cars actually move through, has not. Nexar's bet is that the way to capture it is not with a fleet of specialized survey vehicles but with the millions of ordinary cars already on the road.
Figures reflect the combined Nexar-Nauto footprint announced in July 2026. All imagery is anonymized and de-identified at the source, so the network can map the world without tracking the people in it.
Nexar runs a hybrid hardware-plus-data model. The dashcams - the Beam2, Beam2 Mini and Nexar One - generate revenue and, more importantly, generate coverage. Every connected camera is a moving sensor. The anonymized imagery those sensors produce feeds CityStream, which Nexar sells as data subscriptions, API access and licensed training datasets.
The customer list runs in two directions. On one side are consumer drivers who want a reliable camera and hazard alerts. On the other are the enterprises and agencies buying intelligence: city and transportation departments mapping their streets, insurers pricing road risk, mapmakers keeping their maps current, and autonomous-vehicle developers who need vast, messy, real-world footage to train perception models.
The problem Nexar solves is one of freshness and blind spots. Maps go stale. Cities can't see their own streets in real time. Autonomous systems fail on the exact edge cases - a temporary barricade, a repainted lane, a delivery truck blocking a curb - that rarely show up in curated datasets. Nexar's network, because it rides on cars that are already everywhere, catches those changes as they happen.
LTE-connected cameras (Beam2, Beam2 Mini, Nexar One) recording up to 4K with automatic cloud backup, live parking alerts and an AI hazard-warning app.
Crowdsourced-vision platform aggregating trillions of anonymized dashcam images into minute-by-minute insight on traffic, infrastructure and city dynamics.
Real-time mapping plus a "virtual camera" that surfaces recent ground-level imagery for any location - no hardware installed on site.
AI that automatically detects, localizes and maps road work zones and barricade elements for public-sector road management.
Vision AI mapping free curb space and parking use through the day, plus API comparison of existing maps against real-world change.
Anonymized, licensed road-scene video used to train autonomous-vehicle and ADAS perception models on the messiness of real driving.
Backers span strategic corporates and specialist venture funds - a mix that reflects Nexar's dual identity as both a consumer-hardware maker and a data-infrastructure company.
Investors include Aleph, True Ventures, Ibex Investors, Alibaba Innovation Ventures, Nationwide, Corner Ventures, Samsung NEXT, Micron Ventures, Qumra Capital and State Farm Ventures.
In a field crowded with camera and telematics vendors - Mobileye, Netradyne, Samsara, Lytx - Nexar's distinguishing move is its position, not just its product. It sells reality data to insurers, cities and AV developers without competing directly against any of them. That neutrality is the pitch: a platform of record that stakeholders can trust precisely because it isn't trying to build a rival autonomous car or insurance product.
The scale helps too. A survey fleet is expensive and thin; a consumer network is cheap and dense. By riding on cameras people bought for themselves, Nexar reaches roads a dedicated fleet would never justify visiting - and revisits them constantly. The Nauto merger doubles down on that logic, folding in years of fleet-based driving behavior to widen the dataset.

Nexar sells LTE-connected dashcams and uses the anonymized imagery they capture to power CityStream, a platform that gives cities, insurers, mapmakers and autonomous-vehicle developers a real-time, ground-level view of roads.
Nexar was founded in 2015 in New York by Eran Shir and Bruno Fernandez-Ruiz. Zach Greenberger is the current CEO.
Nexar raised roughly $150M across five rounds from 2015 to 2021, including a $52M Series C in 2020 and a $53M Series D in 2021.
In July 2026 Nexar and Nauto agreed to merge into an independent infrastructure platform for physical AI, combining 10B+ historic miles of driving data across 50+ countries. Zach Greenberger leads the combined company; Stefan Heck chairs the board.
Nexar anonymizes and de-identifies the imagery its network captures, aggregating it into insights rather than exposing individual footage, so it can map the physical world without tracking specific people.
