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.
ChatGPT surpassed 400M weekly active users in February 2025 and launched GPT-4o with voice, image, and real-time reasoning — the world's most-used AI product.
About

Available as a free web and mobile app with a ChatGPT Plus subscription ($20/month) unlocking GPT-4o, advanced voice mode, image generation, and longer context.
