Rivian has acquired Third Dimension, a UK startup founded in 2024 by Tolga Kart and Piotr Sokólski that raised 7 million dollars in seed funding, and its 15-person team will join Rivian’s autonomy and artificial intelligence team under James Philbin, expanding the company’s London AI hub, TechCrunch reported. Terms of the deal were not disclosed. Rivian collects more than 400,000 driving sequences a day from customer vehicles whose owners have enabled camera sharing, and Third Dimension’s technology is meant to turn that data into simulated 3D worlds where complex driving conditions can be tested without waiting for rare real-world cases.
Rivian buys UK world model startup Third Dimension
Rivian has acquired Third Dimension, a 15-person UK startup that uses artificial intelligence to turn images and video into lifelike 3D worlds, to build simulation for its driver assistance features and planned robotaxi system, TechCrunch reported.
Why it matters: Simulation decides how fast an autonomy program can train and validate on rare, dangerous driving cases without waiting for them to occur on real roads, and Rivian is buying that capability rather than building it from its fleet data alone.
Data as of TechCrunch report of October 22, 2026, read in full, based on an exclusive interview with Rivian and Third Dimension executives; single-source limitation flagged, and the deal terms were not disclosed, so this item is graded C. Developing item.
