OpenAI has acquired the AI personal finance startup Hiro Finance, as announced by founder Ethan Bloch and confirmed by OpenAI. The acquisition is characterized as an "acquihire," with Hiro ceasing operations on April 20 and data deletion scheduled for May 13. Hiro employees, including Bloch, are joining OpenAI. Founded in 2023, Hiro offered an AI tool that modeled financial scenarios for consumers based on their inputted financial data, with a focus on accurate financial math. This move aligns with OpenAI's goal of enhancing its capabilities in business finance, especially given the increasing mathematical proficiency of its frontier models and OpenAI's existing positioning of ChatGPT for financial teams. Bloch previously founded Digit, a successful digital-only bank sold for over $200 million.
