SAP Acquires Tabular AI Pioneer Prior Labs, Pledges €1B+ to Build European Frontier Lab

SAP announced on May 4 that it has signed a definitive agreement to acquire Prior Labs, the German startup behind Tabular Foundation Models, and will invest more than €1 billion over four years to scale it into what the company calls "a globally leading frontier AI lab for the structured data that runs the world's businesses." Deal terms were not disclosed, with closing expected in the second or third quarter of 2026 pending regulatory approvals.

Prior Labs, headquartered in Freiburg with offices in Berlin and New York, was founded by Frank Hutter, Noah Hollmann, and Sauraj Gambhir. The team published TabPFN — the foundational result behind Tabular Foundation Models — in Nature, and the open-source model has been downloaded more than three million times. Unlike large language models that operate on text, TFMs are purpose-built for the rows-and-columns data inside enterprise systems: tables, numbers, time series, and the messy structured records that drive most business decisions.

SAP's pitch is that the next leg of enterprise AI will be won on structured data, not chat. "Early on, SAP recognized the greatest untapped opportunity in enterprise AI wasn't large language models; it was AI built for structured data," CTO Philipp Herzig said in the announcement. The company sees TFMs as the right tool for predicting payment delays, supplier risk, customer churn, and upsell potential — workflows that LLMs handle awkwardly because they were never designed for tabular reasoning.

Prior Labs will continue to operate as an independent unit to preserve research velocity, while plugging into SAP's product stack. The team's models will be deployable through SAP AI Core, draw enterprise data from SAP Business Data Cloud, and feed into Joule, SAP's agentic layer. SAP also committed to keeping TabPFN open-source — a notable choice given the commercial pressures that have pulled rivals toward closed weights. "Joining SAP gives us the resources, data environment and customer reach to take this category to its full potential," said Prior Labs CEO Frank Hutter.

The acquisition is the second AI deal SAP unveiled this week — the company also agreed to acquire open-source data-lake platform Dremio — and signals an unusually large bet that Europe can build a homegrown frontier lab around a category Silicon Valley has largely ignored. With Cohere and Aleph Alpha merging on a sovereign-AI platform last week, and Mistral pushing into agentic coding, SAP's €1 billion commitment marks the third major European AI consolidation move in less than two weeks.
