Zach Greenberger

Zach Greenberger is the CEO of Nexar, the New York-based real-world intelligence platform building the data backbone for the Physical AI era. A self-described non-engineer who taught himself the technology, he came up through IBM, Tesla, and Lyft (where he was Chief Business Officer) before taking the top job at Nexar in September 2024. Under his watch Nexar agreed to merge with Nauto in July 2026, uniting a dataset of more than 10 billion driving miles and creating an independent platform of record for how the physical world actually behaves.
