Zoox, Inc. is an American autonomous-vehicle company headquartered in Foster City, California. Since June 2020 it has operated as a wholly owned subsidiary of Amazon. Zoox is unusual in the autonomous vehicle industry because its product is not a self-driving kit bolted onto a regular car. The company designed and manufactures a purpose-built electric robotaxi from scratch: a four-passenger pod with no steering wheel, no driver seat, and no defined front or back, which can drive forward and backward equally well at speeds up to 75 mph (121 km/h).
The company was co-founded in 2014 by Tim Kentley-Klay, an Australian designer with a background in animation and advertising, and Jesse Levinson, who completed his computer science PhD under Sebastian Thrun at Stanford University and led the team behind Junior, the second-place finisher at the 2007 DARPA Urban Challenge. Aicha Evans, a former chief strategy officer at Intel, has served as chief executive since February 2019. Zoox launched a free robotaxi service to the public on the Las Vegas Strip in September 2025 and began offering rides in San Francisco in November 2025, putting it in direct competition with Waymo and Tesla's robotaxi efforts.
Kentley-Klay and Levinson met in 2013 through a mutual acquaintance at Stanford. Kentley-Klay had no automotive or AI background. He had read a 2012 blog post about Google's self-driving car project and convinced himself the eventual production design would not be a retrofitted Lexus. Levinson, by then a postdoc, had spent years building Junior, the autonomous Volkswagen Passat that took second place behind Carnegie Mellon's vehicle in the 2007 DARPA Urban Challenge. Junior's perception and planning code became part of the technical foundation Sebastian Thrun later took to Google.
The two incorporated Zoox in 2014. From the start they argued that retrofitting human-driven cars was a dead end. A vehicle without a driver, they reasoned, did not need a hood, a long crumple zone in front of a missing engine bay, or a steering column. It did not need a defined front and back at all. The bidirectional, carriageless robotaxi became the company's calling card and its biggest engineering bet.
For the first three years Zoox was secretive even by Bay Area startup standards. The first public photographs of an early concept did not appear until 2016. The company did show working test cars, but those were retrofitted Toyota Highlanders used to map cities and validate software, not the eventual production vehicle.
Zoox raised about $990 million across roughly six private rounds before being acquired. The headline round was a Series B announced in July 2018: roughly $500 million at a $3.2 billion post-money valuation, led by Mike Cannon-Brookes's Grok Ventures with participation from Lux Capital, Threshold Ventures, Blackbird Ventures, and Alium Capital. At that point Zoox was one of the most valuable private autonomous-driving startups in the world, behind only Waymo and roughly comparable to Cruise and Argo AI.
The round closed in July 2018. Five weeks later the board fired its CEO.
On August 22, 2018, Zoox's board dismissed Kentley-Klay as chief executive. He learned of the decision the same day and described the move publicly as having been done "without warning, cause or right of reply." Reporting from Axios, Bloomberg, and TechCrunch at the time framed the dismissal as a personality and management issue rather than misconduct. Investors had grown frustrated with what was described as an abrasive, uncompromising style, and many of them privately viewed Levinson, the co-founder and CTO, as the technical lead the company could not afford to lose.
Levinson stayed on and was promoted from CTO to president. Carl Bass, the former CEO of Autodesk who had advised Zoox since 2016 and joined the board in 2017, took over as executive chairman during the search for a new permanent CEO. The board did not put a Kentley-Klay replacement in place for several months.
In February 2019, Zoox named Aicha Evans as chief executive. Evans had spent twelve years at Intel, most recently as chief strategy officer, and before that ran the company's wireless engineering organisation. She arrived at Zoox at a difficult time. The company had a roughly billion-dollar valuation gap to close between its 2018 round and the public market, the prototype car was unfinished, and the autonomous-vehicle hype cycle was beginning to deflate. The 2019 timeline that several rival companies had floated, of public robotaxi service "by next year," was already slipping for everyone.
Evans's near-term focus was operational. She brought in senior engineering leaders, restructured the program, and pushed Zoox toward a more disciplined release cadence. Reporting from The Information and Bloomberg through 2019 and 2020 described Zoox as cash-strapped relative to its ambitions. By spring 2020 the company was looking for additional capital, which is the context in which Amazon entered the picture.
On June 26, 2020, Amazon announced an agreement to acquire Zoox. The deal closed later that summer. Most reporting at the time put the price at slightly above $1.2 billion, with VentureBeat and others describing a roughly $1.3 billion total package once a $100 million stock retention pool for employees was included. The price was a steep discount to the $3.2 billion valuation Zoox had carried since 2018, a reflection of both the broader compression in private autonomous-vehicle valuations and Zoox's specific need for capital.
Amazon committed to keeping Zoox as a standalone subsidiary rather than folding it into Amazon's logistics or devices groups. Aicha Evans stayed on as CEO. Jesse Levinson continued as CTO. The reporting line from Zoox into Amazon eventually went through Panos Panay, who joined Amazon as senior vice president of Devices and Services in 2023.
For Amazon, the rationale was strategic rather than near-term. The company already had a separate logistics-focused autonomy effort (its investment in Aurora Innovation, retrofitted last-mile vans, the Scout sidewalk-delivery program) and Zoox gave it a credible play in passenger autonomous mobility without competing head-on with the big-tech driving programs at Alphabet or Tesla.
On December 14, 2020, Zoox publicly unveiled its production-intent robotaxi for the first time. The reveal was virtual, held during the COVID-19 pandemic, with footage of the vehicle driving on closed roads in Foster City. It was the first purpose-built robotaxi the industry had seen in working form.
The vehicle is striking from across a parking lot. It is small, about 3.63 metres long, with a roughly square footprint and a flat windshield at each end. Inside, four passengers sit facing each other in a carriage layout that is closer to a London hackney cab or a hotel shuttle than to a sedan. There is no driver. There is no place for a driver. There is no front and no back: the vehicle has identical sensor housings at all four corners and four-wheel steering, and the cabin lighting and climate are arranged to be symmetric in either direction of travel.
| Property | Value |
|---|---|
| Length | 3.63 m |
| Top speed | 75 mph (121 km/h) |
| Battery | 133 kWh |
| Operational duration | Up to 16 hours on a charge |
| Passenger capacity | 4, face-to-face carriage seating |
| Steering | Four-wheel, bidirectional |
| Turning circle | ~8.6 m (28.2 ft) |
| Sensor field of view | 360-degree overlapping coverage |
| Sensor range | >150 m in all directions |
| Drive control | No steering wheel, no pedals, no driver seat |
Zoox's sensor architecture is built around the bidirectional pod's symmetry. Each of the four corners of the vehicle carries a sensor pod that combines LiDAR, radar, visual cameras, and longwave-infrared (thermal) cameras. The thermal cameras are supplied by Teledyne FLIR. The four corner pods together produce a 360-degree overlapping field of view; each individual corner sees about 270 degrees, which means at least two pods see any obstacle around the car. This architecture is part of why the vehicle does not need a driver-side / passenger-side distinction: there is no privileged forward-facing sensor cluster.
In addition to camera, radar, and LiDAR, the vehicle uses external microphones to detect emergency-vehicle sirens and an inertial measurement unit for ego-motion estimation. Zoox has published technical material on its long-range radar work and on perception-led design choices for safety-critical autonomy.
The compute stack runs on NVIDIA hardware. NVIDIA confirmed at the December 2020 reveal that the production robotaxi is powered by NVIDIA DRIVE silicon. Public NVIDIA marketing material has named Zoox among the customers for DRIVE Orin, the Ampere-generation automotive system-on-chip that delivers up to 254 trillion operations per second and is rated to ISO 26262 ASIL-D.
Zoox publishes occasional technical writeups through Amazon Science and its own engineering blog, which together give a reasonably clear picture of how the autonomy stack is structured. The pipeline follows the conventional split: perception, prediction, and planning, with map and localisation services running alongside.
For object detection the vehicle fuses LiDAR, camera, radar, and thermal imagery into a unified scene representation. Localisation uses high-definition maps combined with online SLAM-style updates so that the vehicle can find itself even when its surroundings have changed since the last map build, an important property for a service operating on the Las Vegas Strip where billboards and construction barriers move around constantly.
Prediction is multimodal: for every other agent in the scene (cars, pedestrians, scooters, dogs) the planner gets a distribution over possible future trajectories up to roughly eight seconds out, not a single forecast. This matters at intersections, where a pedestrian may either keep walking or stop, and the planner has to keep both branches alive long enough to react to the actual outcome.
In 2023, Zoox researchers published "Scenario Diffusion" at NeurIPS, a generative method for producing safety-critical traffic scenarios for simulation by jointly sampling agent placements and behaviour trajectories. Combined with reinforcement learning and large-scale deep learning, this lets the team train and stress-test planning policies on rare situations the on-road fleet may not have seen recently.
More recent work, presented at AWS re:Invent 2025, described Zoox using AWS SageMaker HyperPod to train multimodal foundation models that ingest camera, LiDAR, and radar simultaneously and output planning decisions, with a training pipeline that begins with supervised fine-tuning on tens of thousands of hours of driving data and then moves to reinforcement learning.
Zoox uses a two-tier fleet. The retrofitted Toyota Highlander SUVs (with safety drivers) handle map-building, software validation, and exploratory testing in new cities. Once Zoox is comfortable with an area, it brings in the bidirectional purpose-built robotaxis and runs them, eventually fully driverless.
The Highlander fleet has been on public roads since 2017, starting in the Bay Area and Las Vegas. In December 2018 Zoox became the first company permitted by the California Public Utilities Commission to carry passengers in self-driving vehicles. In 2020 it became one of a handful of companies cleared by the California DMV to test fully driverless vehicles on public roads. Employee passenger rides on the purpose-built robotaxi began in early 2023.
In June 2024 Zoox expanded testing to Austin and Miami, and through 2025 it added Los Angeles, Phoenix, Dallas, Atlanta, Seattle, and Washington, DC, to its mapping and testing footprint. The company has also tested at Harry Reid International Airport in Las Vegas, an unusually complex environment for autonomous vehicles because of mixed pedestrian, taxi, and shuttle traffic.

For most of Zoox's history, the purpose-built robotaxi was assembled by hand at the Foster City headquarters, in numbers small enough that each car was effectively a prototype. That changed in June 2025, when Zoox opened a 220,000 square foot serial production facility in Hayward, California. The plant was described in coverage by Fortune, ABC7, and TechCrunch as the first purpose-built robotaxi serial production line in the United States. Zoox said the facility, once at full scale, would have capacity for more than 10,000 robotaxis a year.
The assembly process is built around a 21-station line. Robots handle a few specific operations such as glass adhesive application and autonomous vehicle movement between stations. Most of the work, including final fit and finish, is still done by hand, partly because the production rate does not yet justify heavy automation and partly because the modular vehicle architecture is still settling.
Las Vegas was Zoox's first public market. The company chose the city for several reasons: a relatively friendly regulatory environment, wide and well-marked streets along the Strip, and a fleet of high-density attractions that lend themselves to fixed pickup and drop-off points. The free public service launched on September 10, 2025, with five initial pickup and drop-off locations along and near the Strip, including Resorts World, AREA15, Topgolf, New York-New York, and the Luxor. Riders book through the Zoox iOS or Android app. Zoox said in late 2025 that since launching it had logged nearly two million autonomous miles and carried more than 350,000 passengers.
San Francisco followed on November 18, 2025. The launch was technically a public Explorer program rather than a full open-to-anyone service: people on a waitlist were invited in waves as Zoox added vehicles and expanded the service area. The initial coverage was a small slice of SoMa, Mission, and the Design District. By contrast, Waymo at the same point was operating across roughly 260 square miles of the Bay Area, so Zoox's San Francisco footprint was tiny in comparison. Zoox said it expected to begin charging for rides in the second half of 2026, pending CPUC approval and additional NHTSA clearance.
The scale-up has not been free of trouble. In 2025 alone Zoox issued multiple software recalls reported through the National Highway Traffic Safety Administration:
In January 2026 a passenger reportedly suffered an injury after a door strike incident in San Francisco, prompting an SFPD inquiry. As of early 2026 NHTSA had logged on the order of 120 reported incidents involving Zoox vehicles in autonomous mode across all severities, the majority of them low-speed contacts.
The pattern is consistent with what other robotaxi operators have reported during scale-up. Several of the recalls were issued voluntarily under the federal automated-driving recall framework that NHTSA had previously applied to Cruise and Waymo.
The robotaxi market in the United States looks different in 2026 than it did in 2020. Cruise, owned by General Motors, suspended commercial robotaxi operations after a serious incident in San Francisco in October 2023, and GM announced in December 2024 that it was winding the program down. Argo AI, jointly funded by Ford and Volkswagen, shut down in 2022. That left a much smaller field, with Waymo well ahead, Tesla pushing its own robotaxi service from a different technical premise (cameras only, retrofitted production cars), and Zoox occupying a third position with the purpose-built bidirectional vehicle.
| Company | Parent | Sensor approach | Vehicle | Public service status (early 2026) |
|---|---|---|---|---|
| Waymo | Alphabet | LiDAR + radar + cameras | Retrofitted Jaguar I-PACE; Zeekr robotaxi planned | Paid service in San Francisco, Phoenix, Los Angeles, Austin, others |
| Zoox | Amazon | LiDAR + radar + cameras + thermal + microphones | Purpose-built bidirectional robotaxi | Free service in Las Vegas; Explorer in San Francisco |
| Tesla | Tesla, Inc. | Cameras only (HW4) | Model Y for paid pilots; Cybercab purpose-built planned | Limited Austin pilot |
| Cruise | GM | LiDAR + radar + cameras | Chevrolet Bolt; Origin (cancelled) | Robotaxi operations wound down |
| Motional | Hyundai / former Aptiv JV | LiDAR + radar + cameras | Hyundai IONIQ 5 | Restructured; commercial service paused |
| Aurora | Independent | LiDAR + radar + cameras | Class-8 trucks | Commercial driverless trucking, Texas |
In that comparison, Zoox is the only company at scale that has chosen to start with a vehicle that has no human-driving controls at all. Waymo's I-PACE retrofits and Tesla's Model Y still have steering wheels even when no one is using them. The Zoox pod does not. That choice has cost the company years of regulatory work, including the August 2025 NHTSA demonstration exemption that finally cleared the path for the bidirectional vehicle to operate driverless on public roads with passengers.
The period from mid-2024 onward has been the most public chapter in Zoox's history. The June 2024 expansion to Austin and Miami doubled the number of cities where the Highlander mapping fleet was operating. October 2024 brought the formal commitment to put the purpose-built vehicle on roads in San Francisco and Las Vegas. The Hayward factory opening in June 2025 turned what had been a hand-built prototype into a serial product. The September 2025 Las Vegas launch marked Zoox's first revenue-style consumer experience (even if rides were free). The November 2025 San Francisco Explorer launch put the company in the same operational footprint as Waymo for the first time.
In parallel Zoox has expanded its mapping and testing fleet to Phoenix, Dallas, Atlanta, Los Angeles, Seattle, and Washington, DC, signalling intent to deploy in many more US cities in the medium term. The publicly stated near-term target is to begin charging for rides in San Francisco in the second half of 2026, contingent on California Public Utilities Commission approval and continued progress with NHTSA.
For context within the broader space, see Waymo, Tesla, Cruise, Motional, Aurora Innovation, Pony.ai, WeRide, and Apollo Go. Zoox shares the broader autonomous-vehicle ecosystem with Uber and other ride-hailing platforms that are also experimenting with robotaxi integrations, though Zoox runs its own first-party app rather than depending on a third-party network.
