# Rivian Acquires UK-Based Startup Third Dimension for Autonomous Driving Tech

Rivian has acquired UK-based startup Third Dimension, a specialist in AI that converts images and videos into 3D worlds, to accelerate development of advanced driver-assistance features.

Rivian has made a significant move in its bid to become a leader in autonomous driving by acquiring Third Dimension, a UK-based startup specializing in artificial intelligence that can turn images and videos into 3D worlds.

The acquisition is expected to accelerate the development of advanced driver-assistance features and self-driving systems for Rivian's planned robotaxis, which will supply ride-hailing services through partnerships with companies like Uber. The technology has broader applications, but Rivian is primarily interested in leveraging it to enhance its autonomous driving capabilities.

Rivian's acquisition of Third Dimension comes after the startup secured $7 million in seed funding from venture capital firms such as Abstract Ventures and Soma Capital. Founded by Tolga Kart and Piotr Sokólski in 2024, Third Dimension initially developed its technology with an eye on speeding up video game development.

However, the company's founders saw potential for their AI to be used in other areas, including defense and autonomous vehicles. Under Rivian, they will now focus exclusively on developing automated driving capabilities, a problem that Kart believes has significant scale and impact.

The 15-person team at Third Dimension will join Rivian's autonomy and AI team led by James Philbin, with the acquisition also providing an opportunity for Rivian to expand its presence in London.

The acquisition of Third Dimension by Rivian marks a significant step towards bridging the gap between simulated and real-world driving environments for autonomous vehicles.

Historically, simulators have been built on rendering or video game engines, relying heavily on synthetic data to create virtual environments that mimic reality. However, these simulations often fall short in accurately replicating the complexities of the physical world, leaving a quality gap that can be challenging to overcome.

The workaround has typically involved feeding simulators with increasingly large amounts of data in an attempt to close this gap. However, this approach is not only resource-intensive but also limited in its ability to truly replicate real-world driving conditions.

Third Dimension's technology uses AI to match the physical world, and when combined with Rivian's vast collection of driving data, it has the potential to create a highly accurate simulator that can accurately model complex driving scenarios.

Rivian's existing fleet of vehicles, including pickup trucks, SUVs, and delivery vans, generates a significant amount of data through external camera sharing. This aggregated and anonymized data is then used to build training models for driving, with over 400,000 sequences uploaded per day from Rivian's customer fleets.

Rivian has acquired a world model startup to accelerate its self-driving ambitions. The acquisition will enable Rivian to leverage advanced machine learning capabilities and tap into vast amounts of real-world driving data.

The startup's technology is designed to process and analyze massive datasets from various sources, including Rivian's own customer fleets. This aggregated and anonymized data is then used to build training models for driving, with over 400,000 sequences uploaded per day. By integrating this technology into its operations, Rivian aims to improve the accuracy and reliability of its autonomous vehicles.

The acquisition marks a significant step forward in Rivian's mission to develop safe and efficient self-driving technologies. With this advanced capability, Rivian is poised to accelerate its progress in the autonomous vehicle space.
