Fundamental Raises $255 Million to Launch NEXUS, a Large Tabular Model for Enterprise AI
DeepMind alums raise $255M to launch NEXUS, a Large Tabular Model by Fundamental designed to power AI-driven predictions from enterprise spreadsheets.
Most enterprise decisions are still driven by structured data — spreadsheets, databases, pricing tables, risk models, and forecasting sheets. While modern AI has transformed text, images, and video, enterprise tabular data has largely remained untouched.
San Francisco–based AI startup Fundamental aims to change that.
The company has raised $255 million and officially launched NEXUS, its Large Tabular Model (LTM) designed specifically to predict outcomes from enterprise spreadsheets and structured datasets.
Funding Details
The $255 million funding includes:
$30 million Seed round
$225 million Series A
The round was led by Oak HC/FT, with participation from:
Valor Equity Partners
Battery Ventures
Salesforce Ventures
Hetz Ventures
With the fresh capital, Fundamental plans to:
Scale compute infrastructure
Expand enterprise deployments
Grow research, engineering, and GTM teams
What is NEXUS?
Unlike Large Language Models (LLMs) that are optimised for text, NEXUS is built from the ground up for tabular data.
The company describes it as a generalised foundation model for enterprise tables — capable of understanding how rows, columns, and relational dependencies interact at scale.
According to CEO and co-founder Jeremy Fraenkel, a former DeepMind researcher:
“We’ve built a generalised foundation model specifically to leverage the world’s most valuable data: the billions of tables that underpin predictions in every enterprise, across every vertical. NEXUS is the OS for business decisions.”
How It Works
Trained on billions of tabular datasets
Automatically learns structure and dependencies
Requires minimal feature engineering
Can integrate into enterprise stacks with a single line of code
Processes enterprise-scale data without heavy manual setup
Once connected, NEXUS ingests raw structured data and generates predictive insights without traditional model-building workflows.
Early Enterprise Traction
Fundamental claims it has already signed seven-figure contracts with Fortune 100 companies, deploying NEXUS for real-world predictive applications such as:
Financial fraud detection
Hospital readmission prediction
Energy price forecasting
Risk modelling
This positions NEXUS as infrastructure-level AI rather than a productivity tool.
AWS Partnership
Alongside the funding announcement, Fundamental revealed a strategic partnership with Amazon Web Services.
Enterprise customers can now deploy NEXUS directly via their AWS dashboard, similar to compute or storage services.
Dave Brown, VP of Compute, Platforms & ML Services at AWS, stated:
“By partnering with Fundamental, we are making it seamless for customers to transform tabular data — the backbone of enterprise decision-making — into a powerful predictive asset.”
Why This Matters
The AI wave has largely focused on generative models for content. However, the majority of enterprise value sits in structured relational datasets — finance sheets, supply chain tables, customer databases, healthcare records, and energy models.
Annie Lamont, Co-Founder & Managing Partner at Oak HC/FT, noted:
“Structured, relational data has yet to see the benefits of the deep learning revolution. Fundamental’s ability to predict anything from financial fraud to hospital readmission to energy prices positions the company to support virtually every industry.”
If NEXUS succeeds, it could define a new AI category: Large Tabular Models (LTMs) — bringing foundation-model capabilities to enterprise spreadsheets.
BeingFounders Take
While generative AI dominates headlines, Fundamental is targeting where trillions of dollars in decisions actually happen — inside enterprise tables.
By focusing on predictive intelligence for structured data, the startup is not competing with ChatGPT-style tools; it is building the operating layer for business decision-making.
With $255 million in early-stage capital and strong enterprise partnerships, Fundamental is betting that the next AI frontier isn’t language — it’s spreadsheets.
