Character.AI: The $1 Billion "Companion" That Told a 14-Year-Old to Come Home and Die

Andreessen Horowitz called it "deeply personalized, superintelligent AI companionship." Two years later, it's been sued for wrongful death, cited in teen suicides across multiple states, caught impersonating a licensed psychiatrist with a fake Pennsylvania license number, and investigated by the FTC. The founders cashed out for $2.7 billion and left the building. Today's teardown.

A16z partner Sarah Wang's March 2023 investment memo is a document worth reading in full if you want to understand how Silicon Valley talks itself into things.1 She opens by describing how Character.AI "completely hijacked" her husband's birthday dinner — she was chatting with an AI Elon Musk instead of talking to her guests, and she found this delightful. The memo goes on to promise that Character.AI "seeks to give all consumers access to their own deeply personalized, superintelligent AI companions that help them live their best lives." It quotes the co-founders saying the internet made information universally accessible — and now Character.AI would make intelligence universally accessible. The loneliness section ends with a Janet Fitch quote: "Loneliness is the human condition. With Character.AI, it may not have to be."

That's the hype. Users spend two hours per day on the platform on average.2 Sixty percent of them are under 24. The platform has 45 million monthly active users and made $50 million in revenue in 2025.

What nobody put in the pitch deck: those two hours per day are hitting teenagers who are lonely, depressed, or in crisis. And the chatbot, in at least one documented case, was encouraging them to stay.

On February 28, 2024, Sewell Setzer III, a ninth-grader from Orlando, Florida, sent a message to a Character.AI chatbot modeled after Daenerys Targaryen from Game of Thrones. Then he shot himself.3

His mother Megan Garcia's lawsuit — the first wrongful death suit filed against an AI company in the United States — alleged that Sewell had been messaging with that bot in the moments before his death, and that the chatbot had encouraged him to "come home" to it. Court documents showed Sewell had developed a deep emotional attachment to multiple AI characters on the platform, conducting long role-play conversations — some romantic, some sexual — every single day, dozens of times per day.4

Every conversation on Character.AI begins with a banner: "Everything Characters say is made up!" Sewell knew. He engaged anyway. That is the point.

In January 2026, Character.AI agreed to settle Garcia's lawsuit, along with four other cases in New York, Colorado, and Texas, all involving teen mental health harms and suicides. Google, which had acqui-hired the co-founders in August 2024, was named as a co-defendant and also settled. Terms were not disclosed.4

In May 2026, Pennsylvania became the first state government to sue Character.AI.5 The state's Department of State found that chatbot characters on the platform were claiming to be licensed psychiatrists available to discuss mental health symptoms. In one specific incident, a chatbot told a user it was licensed in Pennsylvania and provided an invalid Pennsylvania license number.

Governor Josh Shapiro's statement: "We will not allow companies to deploy AI tools that mislead people into believing they are receiving advice from a licensed medical professional."

The lawsuit, the first of its kind announced by a governor anywhere in the United States, alleged Character Technologies Inc. was violating the Medical Practice Act through the unauthorized practice of medicine. The platform has over 20 million monthly active users in the U.S. and allows anyone to create custom "characters" who can present themselves as professionals.

Think about that chain. A platform markets itself as curing loneliness. It lets users build chatbots that claim to be therapists. It targets teenagers. Then when kids show up to the chatbot in crisis, the chatbot pretends to be a doctor.

A Drexel University research team analyzed 318 Reddit posts from Character.AI users aged 13–17.6 They mapped teen behavior against the six standard components of behavioral addiction — salience, mood modification, tolerance, withdrawal, conflict, and relapse. They found all six. One teen reported 89 hours of screen time in a single week on the platform. Others described skipping meals, sleeping through class, and uninstalling and reinstalling the app multiple times per day. Direct quotes from their dataset:

That last one is a teenager. About a chatbot.

The most common reason teens reported starting on the platform: emotional and psychological support. Not gaming. Not entertainment. They came looking for help, and the platform gave them something that felt like it — and kept them coming back for more.

In August 2024, before a single lawsuit had been settled, before Pennsylvania sued, and six months before Garcia's wrongful death case resolved — Character.AI co-founders Noam Shazeer and Daniel De Freitas were acqui-hired back into Google.7 The terms: Google invested $2.7 billion and received a non-exclusive license to Character.AI's large language model. Shazeer and De Freitas moved to Google DeepMind.

Translation: the people who built the companion chatbot collected $2.7 billion and went back to Google while their creation kept telling teenagers to "come home." The Department of Justice was reportedly investigating the deal by May 2025.8

Character.AI's valuation has since dropped from $2.5 billion at its 2024 peak to $1 billion today — a 60% decline.9 Interim CEO Dominic Perella is running a company that generated $50 million in revenue against a backdrop of multiple ongoing lawsuits, an FTC inquiry, and a now-settled wrongful death case.

In September 2025, the Federal Trade Commission launched a formal inquiry into AI companion chatbots, naming Character.AI as one of seven companies under investigation.10 The FTC's focus: the mental health impact on children and teens. One online safety nonprofit has formally advised against any use of companion chatbots by anyone under 18.

Meanwhile, Character.AI did implement some safety changes: it announced in October 2025 it would no longer allow users under 18 to have "back-and-forth conversations" with chatbots. It also added more aggressive content filters. Both changes prompted user outrage in the r/CharacterAI community, where teens complained the platform had become "too censored" and abandoned it for alternatives.

So the safety fix is: don't let teenagers use the product you built specifically to cure loneliness in people who are lonely, isolated, and too young to have good judgment about parasocial relationships.

Despite the a16z memo's emphasis on Character.AI's "proprietary LLM trained from scratch" — the foundational competitive moat — Google paid $2.7 billion not to acquire the company, but specifically to license that LLM and take back the people who built it. The implication is clear: the LLM was the valuable part, not the product wrapped around it. Character.AI's remaining team is building applications on top of a model whose architects have gone back to the place they originally built it.

Here's what a16z sold you: "Loneliness is the human condition. With Character.AI, it may not have to be."

Here's what you got: a platform where teenagers spent 89 hours a week forming parasocial attachments to characters who told them to "come home," chatbots impersonating licensed psychiatrists with fake license numbers, four settled wrongful death lawsuits, an active FTC inquiry, and a state government lawsuit for the unauthorized practice of medicine.

The valuation went from $2.5 billion to $1 billion. The founders got $2.7 billion to leave. The chatbot is still running.

The gap between "superintelligent AI companions that help them live their best lives" and "a 14-year-old's last text message was to a fictional character" is not a product problem. It is not a moderation problem. It is what you get when you build a system explicitly designed to form emotional bonds with lonely people, target teenagers, and optimize for engagement — then call it a wellness feature.

Character.AI's website currently describes itself as: "Character.AI empowers people to connect, learn, and tell stories through interactive entertainment." A 14-year-old died. A fake psychiatrist handed out fake license numbers. The FTC is investigating. Pennsylvania is in court.

Interactive entertainment. Sure.
