Mark Zuckerberg
CEO of Meta, which is investing tens of billions into AI and AI agents.
Mark Zuckerberg is the co-founder and CEO of Meta, the company that owns Facebook, Instagram and WhatsApp. In recent years he has redirected much of Meta’s enormous budget toward artificial intelligence, including a costly push to build AI agents that can act on a user’s behalf.
He matters to AI watchers because Meta operates at a scale few companies can match, and because Zuckerberg has been unusually willing to spend — and occasionally to admit when the spending has not yet paid off. His candid acknowledgement that agents are harder to build than promised was a rare, useful reality check in an industry prone to overselling.
Meta is also notable for releasing some of its models openly, a strategy Zuckerberg has defended as good for both the company and the wider field.
