On February 5, 2026, Fundamental.ai, an AI company headquartered in San Francisco, California, officially announced the completion of a $255 million Series A funding round, valuing the company at $1.2 billion post-money. This achievement elevates it to the ranks of AI unicorns, demonstrating the capital market’s strong recognition of the enterprise-level AI application sector.
As a rising force focused on enterprise-level AI applications, Fundamental breaks away from mainstream AI models, focusing on the often-overlooked pain points of enterprise structured data processing. Its core product, the Nexus large table model, abandons the traditional Transformer architecture, adapting its deterministic output characteristics to meet the core decision-making needs of enterprises.
This funding round consisted of a $30 million seed round and a $225 million Series A (primary) round, led by Oak HC/FT, with participation from Valor Equity Partners and other institutions. Several tech executives, including the CEO of Perplexity, served as angel investors.
Founded in October 2024, Fundamental is an AI lab focused on enterprise structured data. Its core product, the Nexus large table model, aims to overcome the limitations of traditional LLM models for processing tables and databases. At its recent launch, Fundamental also announced a strategic partnership with AWS.
The funds raised will reportedly be used to expand computing power, grow the team, and commercialize the technology. This newly publicly announced company, with its differentiated positioning, is poised to gain a competitive edge in the enterprise AI data processing sector.
