What Fundamental does
Fundamental is an AI research company that builds NEXUS, a Large Tabular Model (LTM) foundation model purpose-built for enterprise predictive analytics on structured (tabular) data. Founded in October 2024 by DeepMind alumni, the company positions NEXUS as an alternative to general-purpose LLMs (which fail on tabular data due to tokenization, context-window, and precision issues) and to traditional gradient-boosting pipelines (which require months of bespoke feature engineering per use case). The model uses a proprietary non-transformer architecture, is pre-trained on billions of real-world tables, and produces deterministic outputs with no hallucination risk; it is invoked through a scikit-learn-style Python SDK and deploys either directly from Fundamental, as a single-tenant network-isolated endpoint on Amazon SageMaker inside the customer's own AWS account, or via a hardware-attested confidential computing platform that keeps both model IP and customer data isolated.
The company sells to Fortune 100 enterprises across financial services, insurance, healthcare, energy, mining, telecom, retail, supply chain, and manufacturing, with use cases spanning fraud detection, demand forecasting, predictive maintenance, churn prediction, underwriting, and revenue forecasting. Revenue mechanics combine seven-figure enterprise subscription contracts (sold direct and via AWS Marketplace), usage-based inference consumption on customer-owned SageMaker infrastructure, and Forward Deployed Engineer (FDE) professional services that drive Proof-of-Value engagements and integration. Distribution is anchored by flagship partnerships with AWS and SAP and a Cloudera Enterprise AI Ecosystem seat, supported by a content- and thought-leadership-heavy marketing program.
Fundamental is privately held, headquartered in San Francisco, with research hubs in Barcelona and Tel Aviv and a Houston-based energy vertical presence. As of February 5, 2026 (stealth emergence date), the company had raised a cumulative $255 million across a $30 million seed and a $225 million Series A led by Oak HC/FT at a $1.2 billion post-money valuation, with participation from Salesforce Ventures, Valor Equity Partners, Battery Ventures, and Hetz Ventures. No revenue figure is publicly disclosed.

Product offeringCore offering
Fundamental builds and sells NEXUS, a Large Tabular Model (LTM) foundation model that performs enterprise predictive analytics on structured tabular data. Pre-trained on billions of real-world tables, NEXUS replaces months of bespoke feature engineering and model selection with a single pretrained model invoked via one line of code, supporting fraud detection, demand forecasting, predictive maintenance, churn, underwriting, and time series forecasting for Fortune 100 enterprises.
Product overview
Fundamental offers a single core foundation model — NEXUS, a Large Tabular Model (LTM) — supported by a small set of named developer and deployment assets that together form one unified enterprise predictive-AI platform rather than a suite of separate SaaS products. At the center is NEXUS itself (the pretrained LTM, accessible at fundamental.tech/nexus), which is invoked through the Fundamental Python SDK and exposed to enterprise customers through a scikit-learn-style fit()/predict()/predict_proba() interface. NEXUS is available through three deployment surfaces that work as a single product family: (1) the NEXUS on Amazon SageMaker option (a single-tenant, network-isolated SageMaker endpoint distributed via AWS Marketplace), (2) the NEXUS Confidential Computing Platform (a hardware-attested in-VPC deployment for regulated buyers), and (3) the direct-from-Fundamental channel. Capability-wise, NEXUS bundles general tabular predictive analytics with a dedicated NEXUS Time Series Forecasting module that automatically selects and combines forecasting architectures. A public-facing showcase, the NEXUS World Cup Prediction app at soccer.fundamental.tech, demonstrates the model's capabilities on real-world match data. Together, these constitute a tightly integrated product portfolio anchored on one foundation model.

Products and services
- NEXUS Large Tabular Model Fundamental's flagship Large Tabular Model (LTM) foundation model, pre-trained on billions of real-world tables to perform enterprise predictive analytics on structured data. Replaces months of feature engineering and bespoke ML pipelines with a single pretrained model accessed via one line of code, supporting fraud detection, demand forecasting, predictive maintenance, churn, underwriting, and time series forecasting. Uses a non-transformer deterministic architecture with no hallucination risk, deployable directly from Fundamental, via Amazon SageMaker, or within customer VPCs using Fundamental's confidential computing platform.
- Fundamental Python SDK Python SDK providing a scikit-learn-style interface (fit(), predict(), predict_proba()) to the NEXUS model. Handles serialization, endpoint invocation, asynchronous polling, and model management when connected to a NEXUS SageMaker endpoint. Designed for enterprise-scale workloads including gigabyte-scale datasets, dedicated GPU instances, asynchronous inference, and S3-native data movement.
- NEXUS on Amazon SageMaker NEXUS distributed via AWS Marketplace as a model package that deploys as a dedicated, single-tenant, network-isolated Amazon SageMaker asynchronous inference endpoint inside the customer's own AWS account. Datasets remain in the customer's S3 buckets; inputs, outputs, and model artifacts never transit a Fundamental-controlled environment, and the container runs network-isolated with no outbound calls during inference.
- NEXUS Confidential Computing Platform Hardware-backed deployment platform that allows NEXUS models to run inside a customer's VPC with cryptographic attestation. The verified software-stack fingerprint is embedded in the key-release policy so the encrypted model only decrypts if the runtime matches the approved fingerprint. Designed for regulated industries (banking, healthcare, energy) where neither data nor model IP can leave its respective environment.
- NEXUS World Cup Prediction (soccer.fundamental.tech) Public demonstration application that uses NEXUS to predict outcomes of the 2026 FIFA World Cup match-by-match, drawing on 42,000 historical international matches plus recent form. Reports title-win probabilities and correct-call rates, serving as a public showcase of NEXUS applied to sports prediction.
Quantifiable outcome
- 81% of decisive 2026 World Cup group-stage matches called correctly by NEXUS; Argentina flagged as 17.2% title favorite vs market's 12% (Polymarket).
