What happened

Rivian receives more than 400,000 driving sequences a day from customer vehicles, according to its autonomy chief James Philbin, and it has now acquired Third Dimension, a UK-based startup that turns camera footage into controllable 3D scenes. The 15-person team, most of it in the UK, joins Rivian's autonomy and AI group; terms were not disclosed. Rivian plans to use the tool to simulate rare driving situations for its driver-assistance software and for the robotaxi system it plans to supply to Uber, instead of waiting for them to occur on the road.

What we know

TechCrunchtechcrunch.comThe Next Webthenextweb.com
  • Rivian acquired Third Dimension, a startup founded in 2024 by Tolga Kart and Piotr Sokolski, per TechCrunch and The Next Web. Deal terms were not disclosed.
  • Third Dimension has 15 staff, most in the UK, and raised $7 million in seed funding from Abstract Ventures, MVP, Soma Capital and Solari Capital, per TechCrunch.
  • Rivian gets more than 400,000 sequences a day from vehicles whose owners have enabled external camera sharing, per Philbin in TechCrunch. The data is aggregated and anonymized, per TechCrunch.
  • Engineers can change camera positions, other road users, lighting and weather in a reconstructed scene, per Philbin as reported by The Next Web.
  • The team will help Rivian expand its AI hub in London, per Philbin in TechCrunch. Per The Next Web, Rivian plans to release point-to-point supervised driving software by the end of this year, with R2 robotaxi versions due on Uber's app in 2028.

What we don't know yet

  • The purchase price and whether any Third Dimension staff or founders have retention terms were not disclosed.
  • No performance data shows how closely the reconstructed scenes match real driving, or how much the simulator will improve Rivian's driving software; Kart's comparison with game-engine simulators is his own account.
  • It is not known which other providers Rivian evaluated beyond Philbin's statement that it looked at "a lot of different providers".

Why it matters

Rivian is betting that its customer-fleet camera data, combined with a purpose-built simulator, can speed up validation of the driver-assistance features and robotaxi software it has promised for 2026 and 2028.
