Fundamental Emerges From Stealth With $255M to Launch Enterprise Structured-Data AI Model

Fundamental announced it has emerged from stealth with $255 million in funding and a $1.2 billion valuation to advance a new foundation model designed for structured enterprise data. The company’s Nexus model — described as a large tabular model — is built to analyze massive datasets such as enterprise tables and spreadsheets, an area where traditional large language models often struggle.

CEO Jeremy Fraenkel said Nexus combines predictive AI techniques with modern foundation model training to deliver deterministic, scalable analysis across enterprise workflows. The funding includes a $225 million Series A led by Oak HC/FT, with participation from Valor Equity Partners, Battery Ventures, Salesforce Ventures, and Hetz Ventures. Fundamental has also partnered with Amazon Web Services to enable deployment of Nexus within existing cloud environments.
