Coupa Acquires Rossum for Autonomous Spend Management

Coupa, the leading platform for autonomous spend management, has announced its acquisition of Rossum, the AI-first market leader in intelligent document processing (IDP).

The acquisition – announced at Coupa Inspire 2026 – builds on a partnership that automates complex invoicing for accounts payable (AP) teams to extend IDP capabilities across the entire Coupa portfolio, enabling autonomous spend management with agentic AI. 

Delivering savings

Customers already gain significant value from Rossum’s embedded capabilities in the Coupa platform for AP.

Now, they are being given the opportunity to leverage Rossum’s IDP technology, powered by a specialised transactional large language model (T-LLM) for faster processing, meaningful cost savings and greater data control in complex invoicing across direct and indirect spend. 

"Rossum changes the game entirely," says Leagh Turner, CEO at 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.

"We’ve been able to deliver over US$300bn in customer savings over the past 20 years. With Rossum, we believe we can help them save the next US$300bn in five with a system of decision and intelligence that is unrivalled."

Rossum's AI-first architecture

Rossum brings to the table a purpose-built, AI-first architecture that moves beyond legacy OCR technology. Its transactional intelligence is powered by a proprietary domain-specific model trained on tens of millions of documents, continuously learning from each customer's unique document set to accelerate time-to-value.

Combined with Coupa's Navi agentic fleet, customers stand to gain the full benefits of IDP across their entire source-to-pay process. 

"Joining Coupa is the natural evolution of a years-long partnership built on a shared AI-first culture," adds Tomáš Gogár, Co-Founder and CEO at Rossum.

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

"We’re excited to join Coupa, especially at this critical acceleration of how businesses use and adopt AI."

Kirkland & Ellis LLP served as counsel to Coupa with respect to the transaction. Guggenheim Securities, LLC served as exclusive financial advisor and Orrick, Herrington & Sutcliffe LLP served as legal advisor to Rossum.

Attendees at Coupa’s flagship annual event, Coupa Inspire 2026, will have a chance to learn more about the power of combining Coupa and Rossum in the Expo Hall and other informative sessions.
