Wuhan-based Butterfly Effect has raised $75 million for its AI agent product, Manus. Manus is an AI agent that helps with everyday tasks and utilizes a browser-based sandbox to allow user supervision. Startups like Genspark and Flowith are following closely, boasting comparable scores. While US AI companies are hesitant to launch in China due to regulatory issues, Manus aims to expand overseas with new offices in San Francisco, Singapore, and Tokyo.
