Character.AI’s CEO returns to Google in massive licensing deal

Silicon Valley's favorite legal loophole just claimed another massive AI startup.

Character.AI co-founder and CEO Noam Shazeer is heading back to Google, nearly three years after quitting the search giant to build the popular role-playing chatbot platform. Co-founder Daniel De Freitas and a select group of researchers are joining him at Google DeepMind.

Alongside the talent grab, Google signed a non-exclusive licensing agreement for Character.AI's technology, pumping fresh capital into the startup. Dominic Perella, the company's general counsel, will step in as interim CEO, while the startup insists most of its staff will remain put.

Giving up on the pre-training dream

Shazeer is legendary in AI circles for co-authoring the seminal Transformer paper and spearheading Google's LaMDA model. After walking away in October 2021, he raised over $150 million, mostly from a16z, turning Character.AI into an engagement monster among young users.

However, building foundation models from scratch has simply become too expensive. In a blog post, Character.AI admitted that the landscape has changed. When they launched, they had to build full-stack, from pre-training to consumer apps.

Now, with abundant third-party LLMs available, the startup says it will lean heavily on external models alongside its own, pouring its remaining resources entirely into post-training and product features.

The reverse acqui-hire playbook

If this sounds eerily familiar, that is because Microsoft just did the exact same thing with Inflection AI. Rather than outright acquiring the company and inviting brutal antitrust scrutiny, tech giants are licensing the tech and scooping up the founders.

Regulators are already catching on. The FTC launched an inquiry into Microsoft's $650 million Inflection deal in June, and the UK's CMA followed suit last month. Google can expect similar heat from the FTC, the DOJ, and European watchdogs for this transaction.

Why it matters

For casual users who spend hours conversing with virtual bots, the platform stays alive for now. But Character.AI is quietly pivoting from a frontier AI lab into a downstream wrapper, and it remains to be seen whether third-party models can preserve the quirky magic crafted by Shazeer's original team.

For the broader ecosystem, this is a glaring white flag for independent foundation model startups. If a high-flying consumer hit with over $150 million in backing cannot afford the pre-training treadmill, virtually nobody outside Big Tech can.

We think Google pulled off a clever coup by repatriating one of its brightest minds back into DeepMind without triggering immediate merger blocks. That said, antitrust regulators are clearly running out of patience with these fake non-acquisitions, and Google might soon find itself answering very uncomfortable questions in court.
