Character.AI

Character.AI built one of the best known consumer chatbot services of the 2020s. Users create or pick a "character" and chat with it. A character can be anything from a fictional hero to a study helper. The service drew millions of users, most of them young. It also drew lawsuits over teen safety and heavy legal and computing costs. In October 2026 the company entered a court-supervised sale under Chapter 11.

The company's job board lists its main location as Redwood City, a short Caltrain ride north of Palo Alto. It does not publish a street address. This profile relies on the company's own announcements, its job listings and reporting by major outlets. The bankruptcy case was still open on November 1, 2026, so some details here will change.

What Character.AI does

The core product is a chat service on the web and in mobile apps. Users can talk to characters other people have made or design their own by writing a description, a greeting and example lines. Many characters are based on fictional works or public figures. Others are original, such as language tutors, writing partners or text adventure games where the character runs the story.

The company added features over time.

• Mobile apps. Apps for iOS and Android arrived in May 2023.
• Subscription. A paid plan called character.ai+ was announced in May 2023 at $9.99 a month, offering faster responses and other perks.
• Group chats. Several users and characters can share one conversation.
• Images and video. Later versions let users create images and short videos with their characters.

Most users were teens and young adults. Wikipedia, citing reporting from early 2024, put daily visitors at about 3.5 million at that point, mostly ages 16 to 30.

The founders and the Google link

Character.AI was founded in November 2021 by two engineers who had spent years at Google, the company that grew up in Palo Alto before moving to Mountain View. Our page on Google's Palo Alto years covers that early chapter.

• Noam Shazeer was a lead author of a 2017 Google paper on the transformer, the design behind nearly every modern chatbot. Business Insider described that paper as widely cited as key to today's chatbots.
• Daniel De Freitas was the lead designer of an experimental Google chatbot first called Meena, which later became LaMDA.

The two left Google after the company declined to release their chatbot work publicly, according to later reporting. They opened a public beta of Character.AI on September 16, 2022, a little over two months before ChatGPT launched.

Funding and the 2024 Google deal

The company raised money quickly.

1. 2021. A seed round of about $43 million at founding, as reported.
2. March 2023. A $150 million round led by Andreessen Horowitz valued the company at about $1 billion.
3. August 2024. Google hired Shazeer, De Freitas and part of the research team and signed a non-exclusive license for Character.AI's technology. Press reports put the deal at about $2.7 billion. The founders went to work on Google's Gemini models.

Deals like this became common in 2024. A large company hires a startup's top researchers and licenses its technology without buying the company outright. Microsoft did something similar with Inflection AI in Palo Alto earlier that year. Character.AI kept its brand, its users and the rest of its staff. Dominic Perella served as interim chief executive. Karandeep Anand, a former Meta executive, took over as chief executive in 2025.

Teen safety and lawsuits

As the service grew, parents and lawmakers raised concerns about young users forming intense attachments to chatbots. Families filed lawsuits against the company in Florida, Kentucky and Pennsylvania over harm to teenagers, according to reporting on the bankruptcy. Google was also named in some cases.

Character.AI changed its product in steps.

• December 2024. It introduced a separate model for users under 18, with stricter filters on sensitive topics.
• October 2025. It announced that users under 18 would no longer be able to create or chat with characters in open-ended conversations, starting November 25, 2025. Younger users kept access to past chats and to some image and video tools.

This page does not judge the lawsuits. Readers who want the details should look to court records and reporting on each case.

The 2026 Chapter 11 sale

On October 13, 2026, Character.AI announced that it had entered a voluntary Chapter 11 process to run a court-supervised sale of its business. Its board said the process offered the best chance to maximize value for stakeholders. The company pointed to legal, regulatory and operational headwinds.

The key terms reported so far:

• The Walt Disney Company agreed to act as the stalking horse bidder, meaning the opening offer, at $20 million.
• Disney's offer covers a non-exclusive, perpetual license to some of Character.AI's intellectual property, not the whole company.
• Disney hired former Character.AI employees, who were to provide transition services to keep the platform running during the sale.
• Other bidders could top Disney's offer at auction. The company aimed to close a sale in late November or early December 2026.
• NBC News reported estimated assets and liabilities of $50 million to $100 million each.

The company said the platform would stay online and subscriptions would continue during the process. It also said that if no buyer came forward with a plan to keep the service running, it would wind the platform down. Wikipedia reports that 40 state attorneys general filed a notice in the case asking for protections on user data sold in bankruptcy.

Timeline

The pace is the striking part. The company went from founding to a billion dollar valuation in about 16 months. Its founders left within three years. Five years after founding, it was in a court-supervised sale.

Ties to the Peninsula

Character.AI is a product of the Google research world that runs from Mountain View up the Peninsula. Its founders came from Google. Its first big investor, Andreessen Horowitz, is based on Sand Hill Road. Its later deal sent its founders back to Google. Our guide to AI investors on the Peninsula describes how firms there backed consumer AI apps after 2022.
