FactSet offers inter-company relationship data, sourced from SEC filings, investor presentations, and press releases, covering more than 31,000 publicly traded companies worldwide. These relationships are normalized into four categories (Customers, Suppliers, Competitors, and Strategic Partners) spanning 13 specific types, with revenue percentages disclosed where available (roughly 10% of customer-supplier relationships), plus keywords providing context on the nature of each relationship.

Both direct relationships (disclosed by the company itself) and reverse relationships (disclosed by its counterparties) are captured, which  broadens the network beyond what any single company's own filings would show. This makes the dataset useful for mapping corporate supply chains, assessing customer/supplier concentration risk, and tracing dependencies across industries and geographies.
