Commercial clients of American Express will be able to automate expense processing and compliance checks through a new expense management platform launching later this year. The platform is the result of American Express's agreement to acquire Hyper, an AI-driven expense management startup founded in 2022 and backed by OpenAI CEO Sam Altman.
Hyper specializes in the deployment of AI agents that auto-categorize and file expenses, verify them against budgets and company policies, and send reminders for submissions. The two companies had previously collaborated in 2024 to launch the Hypercard Rewards American Express card using the Agile Partner Platform.
CEO Stephen Squeri recently described AI as creating a "structural shift" in the way companies operate in his annual letter to shareholders. Raymond Joabar, Group President of Global Commercial Services at American Express, stated that AI has the potential to transform how businesses get things done. The acquisition is expected to close within the second quarter of 2026, subject to closing conditions.
