About
Zoox is an autonomous vehicle company founded in 2014 by Tim Kentley-Klay and Jesse Levinson, headquartered in Foster City, California. Unlike competitors that retrofit existing cars, Zoox designed a purpose-built robotaxi from scratch — a bidirectional, four-passenger vehicle with carriage-style seating, 360-degree sensing, and four-zone climate control. Amazon acquired Zoox in June 2020 for approximately $1.2 billion.

Grok 3, released in February 2025, achieved top scores on the AIME math reasoning benchmark and ARC-AGI test, briefly positioning xAI as a frontier model lab.
