Rivian Acquires Innovative World Model Startup to Fast-Track Autonomous Driving Goals
Electric vehicle manufacturer Rivian has acquired Third Dimension, a startup from the U.K. founded by experts from the gaming and autonomous vehicle sectors, which specializes in using AI to create realistic 3D environments from images and videos.
While Rivian is not venturing into the gaming world, it aims to utilize Third Dimension’s technology to convert real-world data into immersive 3D settings. This advancement will aid in the enhancement of its driver-assistance features and contribute to the self-driving systems for robotaxis intended for Uber.
Details of the acquisition deal have not been revealed. The 15-member team from Third Dimension, primarily situated in the U.K., will become part of Rivian’s autonomy and AI division, which is overseen by James Philbin. Philbin mentioned that this acquisition also allows Rivian to strengthen its AI base in London.
Founded in 2024 by CEO Tolga Kart and Piotr Sokólski, Third Dimension successfully secured $7 million in seed funding from various venture capital firms. Although the startup’s technology was initially aimed at expediting video game development, its founders recognized additional use cases in defense and autonomous vehicle applications.
Now, as part of Rivian, the focus will shift to driver automation.
“The team is thrilled to concentrate on a singular challenge,” Kart stated in a discussion with TechCrunch. “As a small company, balancing numerous demands is quite challenging, so we are really excited about tackling a problem of such scale, where our technology can make a significant impact.”
Simulation plays a vital role for developers of autonomous vehicles, enabling them to train and verify self-driving technologies. Traditionally, these simulators were developed using rendering or gaming engines, often relying on synthetic datasets. Kart noted that although these virtual settings may resemble the real world, a noticeable difference persists. The usual solution involved feeding simulators larger volumes of data to narrow that quality gap.
The AI technology from Third Dimension aims to closely replicate the physical environment, which, in conjunction with Rivian’s extensive data, could transform into an invaluable simulation tool.
Rivian gathers driving information from tens of thousands of its R1S pickup trucks, R1S SUVs, delivery vans, and R2 SUVs currently operating on the road—essentially any vehicle whose owner has opted for camera sharing. This aggregated and anonymized data is used to develop driving training models. Philbin indicated that Rivian receives over 400,000 sequences from its customer fleets each day.
With Third Dimension’s technology, Rivian will be able to simulate intricate driving situations without waiting for the infrequent real-world edge cases to happen, Philbin added.
