    Character.AI was founded in 2021 by ex-Google Brain researchers Noam Shazeer (Transformer co-author) and Daniel de Freitas. It raised $193M at a $1B+ valuation with 20M+ users chatting with AI characters. On August 2, 2024, Google announced it was hiring Shazeer, de Freitas and ~30 top researchers back, paying Character.AI ~$2.7B for a non-exclusive license — one of the most expensive de-facto acqui-hires in tech history. The consumer product continued with reduced ambitions under a new CEO.

    Character had 20M users and still couldn't cover its GPU bill. That's the story of consumer AI in 2024.

    2. Google's $2.7B license set a Big Tech precedent

    The transaction structure — hire founders + license technology — became a template that FTC antitrust reviewers are now scrutinizing.
