San Francisco Venture Capitalist and Sam Altman's Boyfriend Loses $11M in Cryptocurrency Heist

In late November, a high-profile home invasion in San Francisco’s upscale neighborhoods has sent shockwaves through Silicon Valley’s tech and investment circles. According to police sources and reports from the New York Post, Lachy Groom, a 31-year-old venture capitalist and the former partner of OpenAI co-founder Sam Altman, fell victim to an armed robbery at his residence. The attackers made off with approximately $11 million worth of cryptocurrency assets, marking what investigators believe to be a meticulously planned operation orchestrated by an organized crime syndicate.

The Setup: A Calculated Deception That Breached Home Security

The attack unfolded with chilling precision on a Saturday evening. Surveillance footage captured the suspect dressed as a deliveryman, complete with a white package, approaching the $4.4 million property. When the doorbell rang, the perpetrator introduced himself as “Joshua,” claiming to be a UPS partner employee making a delivery. The ruse worked. Once the victim confirmed he was indeed Joshua and opened the door, the suspect quickly forced his way inside.

What began as a seemingly routine package delivery escalated rapidly into violence. The intruder produced a firearm and held the resident at gunpoint while restraining him with tape. The assault then took a disturbing turn—according to investigative reports, the attacker tortured the victim while maintaining a phone connection to accomplices. A voice with a foreign accent repeatedly recited personal information about the resident over speakerphone, creating a psychological terror campaign alongside the physical assault.

The Crime: Surgical Precision in Digital Asset Theft

Over approximately 90 minutes, the criminal team systematically accessed and emptied every cryptocurrency wallet in the victim’s possession. The theft targeted $11 million worth of Ethereum and Bitcoin holdings, suggesting the operation was not random but rather a targeted attack on a specific high-net-worth individual. Law enforcement arrived at 6:45 p.m. to find the victim bearing multiple bruises from the assault.

The speed and sophistication with which the attackers drained the digital wallets indicated extensive preparation. Investigators believe this operation bears the hallmarks of an organized crime group specializing in targeting wealthy individuals within the tech and venture capital sectors who hold significant cryptocurrency positions.

The Victim’s Profile: Connections and Consequences

Lachy Groom’s background as a venture capitalist positions him within Silicon Valley’s elite investment circles. His previous relationship with Sam Altman, the 40-year-old OpenAI co-founder, placed him adjacent to some of the tech industry’s most powerful figures. Property records reveal that Groom purchased his San Francisco home from the Altman family in 2021 for $1.8 million, later appreciating to its current $4.4 million valuation.

This case has reignited concerns about the security vulnerabilities facing high-net-worth individuals in the cryptocurrency space. The incident demonstrates how personal relationships and public profiles can inadvertently become vectors for criminal targeting, and raises critical questions about asset protection strategies for those holding substantial digital wealth in major financial hubs like San Francisco.
