Founders and top researchers are leaving major AI labs like OpenAI and Google DeepMind to start new ventures, creating interconnected ecosystems often described as 'mafias' that influence the industry.

Arthur Mensch’s move from DeepMind to Paris to launch Mistral AI highlights Europe’s rising role in AI startups, now valued at roughly 33 trillion won.

Mira Murati’s venture Thinking Machines Lab, with its Inkling model, signals a shift toward open or customizable AI systems and pushes back against closed, highly siloed platforms.

The wave is global, with South Korea’s Naver and Kakao acting as incubators for AI startups such as Upstage led by Sung Kim and Karrot led by Kim Yong-hyun and Kim Jae-hyun.

Dealroom data shows that companies founded by members of these AI mafias collectively reach about $2.6 trillion in value, nearly matching the $3.1 trillion attributed to the PayPal Mafia, underscoring their significant impact.

Industry insiders say that as major platforms expand, more researchers will strike out on independent paths, potentially driving rapid, widespread innovation across regions.

A defining pattern is the OpenAI Mafia, with leaders like Dario Amodei founding Anthropic and Ilya Sutskever launching SSI, signaling shifts in leadership and strategic direction.

Notable moves include Aidan Gomez and Noam Shazeer from Google forming Cohere and CharacterAI, with Shazeer later joining OpenAI, illustrating mobility among top AI researchers.
