OpenAI has selected Brex's AI-native corporate card and spend management platform to handle its global financial operations, giving OpenAI's finance teams real-time visibility, automated expense management, and global payment facilitation as the company scales its workforce worldwide. Brex recently launched a ChatGPT integration that lets customers query expense data and policy information directly within the chat interface, deepening the operational tie between the two companies. Brex claims its automation platform saved customers more than 208,000 hours monthly and freed over $163M in annual salary costs across its client base in 2025.
