About
Fundamental is an enterprise analytics AI company that emerged from stealth in February 2026 with a $255 million Series A at a $1.2 billion valuation — one of the rare instant unicorns backed by Oak HC/FT, Valor Equity Partners, Battery Ventures, and Salesforce Ventures. The company's Nexus Large Tabular Model (LTM) is purpose-built for enterprise structured data — rows, columns, and tables — rather than text, addressing the foundational limitation of LLMs applied to business analytics where precision on numerical and categorical data matters more than fluency.
