Before Meta inked its $14.3 billion investment in Scale AI, its founder, Alexandr Wang, had already formed a close relationship with Meta CEO Mark Zuckerberg.
The two reportedly spent time together at Zuckerberg’s homes in Palo Alto and Lake Tahoe, discussing the future of artificial intelligence and the role Scale might play in it. That connection has now crystallized into a formal partnership: Meta has tapped Wang, just 28, to lead its AI efforts.
The appointment came only days after Meta’s major investment and shortly before Scale AI laid off 14% of its workforce—roughly 200 full-time employees. Wang is now in a position to influence the direction of AI development at one of the world’s most powerful tech firms.
Wang, a former MIT dropout, co-founded Scale AI in 2016. The company provides software and labor to help label the vast amounts of data needed to train AI systems, such as large language models. After a brief dip in valuation in 2023, Scale recently rebounded to nearly $14 billion, buoyed by new funding. Wang holds an estimated 14% stake.
Born in New Mexico to Chinese immigrant physicists, Wang was a math prodigy who competed in coding competitions before leaving MIT after one year. His co-founder, Lucy Guo, exited the company in 2018 but retained a significant equity stake, eventually making her a billionaire as well.
Scale’s workforce includes more than 100,000 contractors who annotate data for clients like Meta, OpenAI, and Microsoft. The company’s labor-heavy model has sparked controversy, including multiple lawsuits alleging exploitative conditions and mismanagement. Despite the backlash, Wang has steadily expanded his influence—not just in Silicon Valley but in Washington, where he’s viewed as a key voice shaping the AI regulatory landscape.
Wang’s personal network has played a crucial role in his rise. He is also close with OpenAI’s Sam Altman, who led Y Combinator when Scale went through the accelerator in 2016. Now, with Zuckerberg’s backing and Meta’s resources, Wang is positioned to become one of the most influential figures in the next phase of AI.
