OpenAI has acquired Hiro Finance, an AI-powered personal finance startup, in a move that signals the model maker’s growing interest in specialized financial tools. The acquisition was announced by Hiro founder Ethan Bloch on Monday and subsequently confirmed by OpenAI.
Although the financial terms of the deal remain undisclosed, the nature of the transaction appears to be an “acquihire.” Hiro is scheduled to shut down its operations on April 20, 2026, and will delete all user data from its servers by May 13, 2026 according to reports. As part of the agreement, the Hiro team, including Bloch, will join OpenAI.
Founded in 2023, Hiro Finance launched its consumer-facing AI tool approximately five months ago. The application allowed users to input specific financial data—such as monthly costs, debts, and salaries—to model “what-if” scenarios, helping consumers make more informed financial decisions through AI-driven planning.
Strengthening the Financial Math Capabilities of AI
A primary driver for the acquisition appears to be Hiro’s specialized approach to mathematical accuracy. Ethan Bloch noted in a product demo that Hiro was specifically trained to excel at financial math, even offering a feature that allowed users to verify the accuracy of the calculations. This focus addresses a historical pain point for large language models, which have traditionally struggled with precise arithmetic, even though frontier models have seen significant improvement in recent years.
The deal is particularly notable due to Bloch’s track record in the fintech space. He previously founded Digit, a digital-only bank designed to help users automate their savings. Digit was acquired by Oportun in 2021 for more than $200 million as reported by Oportun.
OpenAI’s strategy seems to be expanding its footprint in the financial sector. The company already markets ChatGPT as a viable tool for business finance teams, and adding the Hiro team provides additional talent to bolster these capabilities.
Impact on Users and Timeline for Shutdown
For current Hiro Finance users, the transition will be swift. The company has already stopped accepting new signups. The wind-down process follows a strict timeline:
- April 20, 2026: Official cessation of Hiro operations.
- May 13, 2026: Complete deletion of all user data from Hiro servers.
Because the startup is shutting down its standalone service rather than integrating it into an existing product, users are encouraged to secure any necessary financial records before the May deletion date.
The Role of Venture Capital in Hiro’s Growth
Before its acquisition by OpenAI, Hiro Finance was backed by several prominent venture capital firms. The startup received support from the fintech-focused firm Ribbit, as well as General Catalyst and Restive as detailed in industry reports. Despite this backing, the company did not disclose the total amount of capital it raised prior to the sale.
The size of the team moving to OpenAI is not officially specified, though LinkedIn data indicates approximately 10 people are associated with Hiro Finance.

Whether OpenAI intends to launch a specialized financial planning application or simply integrate Hiro’s mathematical optimizations into ChatGPT remains to be seen. Still, the move underscores a broader trend of AI giants absorbing niche startups to refine the accuracy and reliability of their models in high-stakes domains like personal finance.
The next critical checkpoint for former users is May 13, 2026, when all remaining data will be permanently removed from Hiro’s servers.
