Fundamental raises $255M Series A at $1.4B led by Oak HC/FT

The $255M combines a $30M seed and a $225M Series A, so the headline figure covers both rounds. Battery Ventures also co-led, and angels included Perplexity CEO Aravind Srinivas and Datadog CEO Olivier Pomel. Valuation reporting differs: TechCrunch cites $1.4 billion post-money, while other outlets report $1.2 billion. The round coincided with the company leaving stealth with Nexus. The model is deterministic and does not use the transformer architecture. The team is about 35 people in San Francisco. Seven-figure Fortune 100 contracts were reported for forecasting, pricing and churn work, and an AWS partnership handles distribution. For founders, the signal is that investors are funding model labs split by data type, not only by scale. Enterprise value sits heavily in tables, where general LLMs perform poorly. Startups selling predictive analytics or data science automation now face a well-capitalized specialist with cloud distribution. Deterministic output is also a selling point for buyers in finance and other regulated sectors, and wrapper products on general LLMs may struggle to match it.
