Coupa acquires AI document processing firm Rossum

Coupa said it has acquired Rossum, an artificial intelligence-driven intelligent document processing company, in a move aimed at expanding automation capabilities across procurement and accounts payable operations.

The company made the announcement during its Inspire 2026 conference in Las Vegas and said the acquisition builds on an existing partnership focused on automating complex invoicing for accounts payable teams. Coupa said Rossum’s technology will now be integrated more broadly across its autonomous spend management platform.

Rossum’s platform uses a transactional large language model trained on millions of documents to process invoices and other business documents beyond traditional optical character recognition technology.

“Rossum changes the game entirely,” said Leagh Turner, CEO of Coupa. “As a strong partner since 2024, we know there is incredible value in bringing the two companies together across the entire source-to-pay function.

“The combined value of Coupa and Rossum has been proven in AP and invoicing, and we see massive future value in applying Rossum’s T-LLM and AI-first technology across the Coupa platform.”

Tomáš Gogár said the deal reflects a shared “AI-first culture” between the two companies.

“By combining our proprietary T-LLM transactional intelligence with Coupa’s massive $10T data set, we are well positioned to create immediate customer value and fundamentally change how the world buys and sells,” Gogár said.

Financial terms of the transaction were not disclosed.

The companies said attendees at Coupa’s Inspire conference will receive more information about the combined offering, while a webinar discussing the acquisition is scheduled for June 9.
