Hiro is an AI personal CFO platform that helped clients manage over $1 billion in assets.

While terms were not disclosed, the deal is being viewed as an acquihire. Founder Ethan Bloch and approximately 10 employees are joining OpenAI. Bloch is a seasoned fintech entrepreneur who previously sold Digit for over $200 million.

Hiro launched its AI tool about five months ago, focusing on "what-if" financial modeling (e.g., salary, debt, and cost analysis). It was specifically engineered to solve the historical struggle of LLMs: accurate financial math.

This acquisition signals OpenAI's growing interest in specialized financial applications, potentially strengthening ChatGPT's utility for business finance teams and individual financial planning.
