On Monday, Ryan Beiermeister announced her new role as a partner at Founders Fund. She is a prominent figure in Silicon Valley for various reasons. Previously, she held the position of VP of Product Policy at OpenAI for around two years, a period during which the organization gained significant recognition, particularly after ChatGPT emerged as the fastest-growing application in history.

Her tenure there came to an unexpected end in February when she was reportedly dismissed after opposing a proposed feature for ChatGPT known as “adult mode,” aimed at enabling adults to utilize the chatbot for erotic content. The Wall Street Journal indicated that her termination was linked to an allegation of sexual discrimination by a male colleague, although Beiermeister vehemently denied any claims of discrimination. In March, OpenAI allegedly abandoned its plans for adult mode.

Lately, Beiermeister has gained further recognition in Silicon Valley for her adept strategy in a Founders Fund YouTube series called “Mafia.” This game requires players to identify which participants are secretly Mafia assassins before those players can “eliminate” the rest.

Beiermeister participated against notable figures such as OpenAI’s Sam Altman, Anduril’s Palmer Luckey, Figma’s Dylan Field, Flexport’s Ryan Petersen, Founders Fund’s Trae Stephens, among others.

One of the most gripping moments in Episode One featured her and Altman each stating that if they were found deceased, it would imply that the other was responsible. Those familiar with their histories found it amusing.

Some users on Twitter speculated that perhaps the entire Mafia game served as a job interview for her. According to the firm’s chief marketing officer and the game’s host, Mike Solana (who introduced the game to the firm), it is frequently played at Founders Fund retreats.

However, that was not the case. “While she is indeed a remarkable Mafia player, that aspect did not factor into her interview. She has had a close relationship with Trae Stephens since their time together at Palantir and has been on friendly terms with our team for many years,” a spokesperson from Founders Fund informed TechCrunch.

Nonetheless, Beiermeister’s gameplay—composed and making insightful observations about who might belong to the Mafia—likely benefited her opportunities.

Beiermeister has known Trae Stephens for at least a decade. Before her time at OpenAI and at Meta previously, she spent her early career at Palantir, the data solutions company founded by Peter Thiel, the founder of the VC firm. Stephens was also part of Palantir during its foundational stage.

Beiermeister states she is keen to support the types of startups that Founders Fund is recognized for favoring.

“The companies that will shape the next twenty years are emerging in sectors where product engineering presents the greatest challenges and stakes are the highest—AI infrastructure and agentic systems, defense, energy, climate, biotech, the regulated frontier,” she stated in a LinkedIn post. “To the founders in these areas, particularly if you don’t conform to the conventional archetype: I am eager to connect, and my inbox is open.”
