OpenEvidence CEO Daniel Nadler Sues Firefighter Milstein, Alleging Damage to $40 Million Malibu Mansion
Daniel Nadler, aged 42 and with an estimated net worth of ≈$7.6 billion as CEO of the Google-backed AI company OpenEvidence — positioned as “ChatGPT for doctors” — has sued a firefighter over alleged damage to his $40 million Malibu, California mansion. According to Patronlar Dünyası, the defendant is Robert Milstein, head of SoCal Fire Supply and an emergency support contractor to the Los Angeles Fire Department. Milstein was installing a fire-resistant system at Nadler's mansion on 9 October 2025; he is known locally as a “firefighter hero” for helping save the famous Calamigos Ranch during the 2018 Woolsey fire and for defending Big Rock during the January 2026 Palisades fire, contributing to the evacuation of hundreds of residents.
In the complaint filed against Milstein, Nadler alleges that he “damaged numerous rammed-earth panels, jeopardising the mansion's exterior facade”. The billionaire argues that because the wall is a rare construction, “partial repairs would only worsen the damage and the structure must be rebuilt as a single piece with a weathered finish” — and seeks “millions of dollars” in damages. Per Patronlar Dünyası, the lawsuit further claims that the damage lowered the resale value of the home and that the property “lost millions of dollars in value”.
The case is illustrative at the intersection of AI technology finance + luxury real estate + fire-services supply chain: OpenEvidence's funding ecosystem — currently in the news for the Google investment — is positioned as an AI clinical decision-support platform offering rapid literature search and diagnostic support to doctors, aiming to build structural value in healthcare AI through regulatory approvals, HIPAA-compliant infrastructure and clinical validation. The broader read of the case highlights that California's growing fire risk has produced a fast-growing private fire-resistant system installation sector where insurance + liability limits + certification standards are not yet settled; cases like this put direct operational-risk pressure on small- and mid-sized contractors such as SoCal Fire Supply. Milstein's 20-year firefighting and fire-services CV also creates a structural asymmetry in public perception of the case.
Key Takeaways:
1. OpenEvidence CEO Daniel Nadler (42, net worth ≈$7.6bn) has sued firefighter Robert Milstein over alleged damage to the rammed-earth wall panels of his $40m Malibu mansion.
