About the company
Character AI builds an AI platform that lets users create and manage virtual characters with distinct personalities for use in games and business applications. The platform enables NPCs and virtual customer service representatives to interact with people in realistic, engaging ways. It works by providing tools to design character personalities, manage their behavior, and deploy them across digital environments, typically via a subscription or licensing model that gives ongoing access and updates. What sets Character AI apart is its focus on both entertainment (gaming) and practical service use, offering a scalable, multi-domain solution with a steady revenue stream rather than a single-market product. The company's goal is to broaden digital interactions by making character-driven experiences more natural and personalized, driving engagement and value for developers and businesses in the growing AI market.

-7%Character.AI, the chatbot startup once valued at $1 billion, has filed for Chapter 11 bankruptcy in the US Bankruptcy Court for the District of Delaware. It seeks a court-supervised sale of its assets and will shut down if no buyer keeps the service running. Disney Worldwide Services has signed on as the lead bidder, offering $20 million for non-exclusive perpetual licences to certain intellectual property and some legal claims, plus transitional services from former employees. Other bidders can still top the offer. The sale is expected to close in late November or early December. The company cited legal and regulatory pressure, monthly operating losses of $8 million to $9 million, and trouble raising capital. It estimated its assets and liabilities at $50 million to $100 million. The app remains online.
Character.AI, the chatbot startup founded by former Google researchers, has filed for voluntary Chapter 11 bankruptcy in Delaware. The California-based company is seeking a court-supervised sale of all or substantially all of its assets, which it expects to finish by late November or early December. Disney Worldwide Services, an affiliate of the Walt Disney Company, is the opening bidder for a non-exclusive, perpetual licence to certain Character.AI intellectual property and claims. Disney would pay $20 million and provide transition services using former Character.AI employees it has hired. Other buyers can still bid higher. The platform stays online during the sale. If no bid is enough to keep it running, Character.AI will wind down the service. The company has faced lawsuits from families who alleged its chatbots harmed teenagers' mental health. It did not say what led to the filing.
Disney has appointed Karandeep Anand as its first chief technology officer. Anand previously led Character.AI, a generative AI startup that Disney accused of copyright infringement in September 2025. Character.AI enables users to create and interact with AI-generated virtual characters. Disney sent the company a cease and desist letter, claiming it hosted copyrighted characters from Disney franchises. The startup has also faced lawsuits alleging its chatbots encouraged self-harm and suicide. New Disney CEO Josh D'Amaro selected Anand for the role after Bob Iger stepped down in March. The appointment signals D'Amaro's intention to embrace emerging technologies. Anand became Character.AI's CEO in May 2025, having previously served as a board adviser. His career includes roles at Facebook and 15 years at Microsoft.
Character.ai is launching AI-generated microdramas with an interactive twist. Users over 18 can chat with characters from the shows, ask questions, and explore alternative storylines. The company is debuting three series: romance drama "Last Summer," horror show "The Nighttime Game," and survival thriller "Eden Fall." All were created using AI production tools. Character.ai plans to eventually allow users to create their own series. The startup is also testing c.ai FM for audio series and c.ai Reads for fiction creation. This marks Character.ai's latest entertainment-focused feature. In April, it launched Lorebook for world-building and Books, which lets users insert themselves into classic literature. According to Sensor Tower, users spend over 950 minutes monthly on Character.ai.
DigitalOcean has announced that its Inference Cloud Platform, powered by AMD Instinct GPUs, is delivering double the production inference throughput for Character.ai, which handles over one billion queries daily. The platform also reduced Character.ai's cost per token by 50% whilst maintaining strict latency requirements. The performance gains resulted from close collaboration between DigitalOcean, Character.ai and AMD to optimise AMD Instinct MI300X and MI325X GPUs specifically for inference workloads. DigitalOcean's platform integrates hardware-aware scheduling and optimised inference runtimes, working with AMD's ROCm software stack and AITER framework. Character.ai's David Brinker said DigitalOcean delivered reliable performance that "unlocked higher sustained throughput and improved economics". The collaboration demonstrates DigitalOcean's strategy of focusing on production outcomes rather than simply GPU availability.
