OpenAI acquired Hiro Finance on April 13, bringing on 10–13 employees in its second fintech acqui-hire in six months. Hiro's AI personal CFO app, which had helped users plan over $1B in assets in five months of operation, shut down April 20; all user data is scheduled for deletion by May 13. Hiro's core differentiation was accurate financial math with built-in verification. Terms were not disclosed. Founder Ethan Bloch previously built automated savings app Digit, sold to Oportun for ~$230M in 2021.
