American Express is buying Hyper, an AI expense management startup co-founded in 2022 and backed by OpenAI CEO Sam Altman. The move is part of AmEx’s push to bring more automation into its commercial products.
Hyper builds AI agents that handle the grunt work of expense management — categorizing costs, filing reports, checking submissions against budgets and company policies, and nudging employees about deadlines.
The two companies already had a working relationship. In 2024, they teamed up to launch the Hypercard Rewards American Express card, which came with built-in AI expense tools powered by AmEx’s Agile Partner Platform.

This acquisition takes that partnership a step further, folding Hyper’s technology directly into AmEx’s operations.
Financial terms of the deal were not disclosed. The transaction is expected to close in the second quarter of 2026, subject to standard closing conditions.
AmEx has been quietly building out its commercial business. Last month, it launched a new commercial credit card with cashback rewards and perks, priced at a $295 annual fee.
The company also has plans to roll out another card later this year.
In his letter to shareholders last month, AmEx CEO Stephen Squeri described AI as creating a “structural shift” in how businesses operate. The Hyper deal fits squarely into that thinking.
Hyper was founded in 2022 with a focus on turning manual expense workflows into automated ones. Its AI agents don’t just sort receipts — they cross-check submissions against company policy and flag anything that looks off.
That kind of compliance automation is increasingly valuable for companies managing large volumes of employee spending.
AmEx has said it plans to launch a broader AI-powered expense management platform later this year, which will incorporate next-generation AI capabilities. Hyper’s technology is expected to play a role in that rollout.
AXP stock moved marginally following the announcement, down around 0.69% on the day.
