April 16 - American Express said on Thursday it will acquire Hyper, a startup that builds artificial intelligence agents for expense management and that counts OpenAI Chief Executive Sam Altman among its investors. Financial details of the transaction were not released.
The move comes as large financial firms accelerate efforts to embed AI into core business software - particularly in areas like expense management where routine tasks, compliance checks and repetitive approvals can be automated. In a letter to shareholders last month, AmEx Chief Executive Officer Stephen Squeri described AI as producing a "structural shift" in how companies operate.
Hyper, founded in 2022, develops AI tools designed to organize and process business expenses. Its software can categorize transactions, prepare expense reports, verify entries against budgets and corporate policies, and issue reminders to employees to submit documentation. The company highlights its relationship with Sam Altman and previously collaborated with American Express in 2024 to introduce a credit card.
American Express indicated that the acquisition is expected to close in the second quarter of 2026. The company did not disclose the price or other financial terms for the purchase.
Executives at AmEx have been expanding the issuer's presence in the commercial market. Last month the company launched a new commercial credit card featuring cashback rewards and additional perks for an annual fee of $295. AmEx has said it will roll out another card later this year.
Company officials and industry observers say the Hyper acquisition could enhance AmEx's ability to offer automation and workflow tools to its commercial customers, potentially strengthening its standing in the corporate spending space. How quickly those capabilities will be deployed and adopted by clients will depend on integration and rollout plans that AmEx has not detailed publicly.
The announcement also underscores a broader trend: established financial firms are investing in AI-driven software to reduce manual effort and streamline compliance-driven processes. For AmEx, adding Hyper's agent-based expense features to its commercial product suite represents a strategic step toward deeper automation for business customers.
AmEx said the deal is expected to close in the second quarter of 2026.
