Hiro

Hiro was the latest venture from Ethan Bloch, who had previously built the savings app Digit and sold it to Oportun for more than 200 million dollars. Founded in 2023 and backed by Ribbit Capital, General Catalyst, and Restive, it pitched a personal AI CFO that could model a user's income, debts, and expenses with arithmetic accuracy that general-purpose chatbots lacked. The financial-planning tool had been live for only about five months when OpenAI acquired the roughly ten-person team in April 2026. It was a talent deal, not a product one: Hiro told users it would shut down on April 20, 2026 and delete their data by May 13. The math-verification work that made Hiro attractive headed into ChatGPT, while the app itself went dark.
