Supply chain database: public company relationships from regulatory filings
ChainSifter is a supply chain database built entirely from SEC regulatory filings. Every supplier relationship, customer dependency, and key partner disclosed in a public company's 10-K, 10-Q, 8-K, or proxy statement is extracted, indexed, and made searchable by ticker.
Named suppliers, manufacturers, distributors, and logistics partners extracted from SEC disclosures across thousands of public companies.
Named customers with disclosed revenue concentration, contract terms, and dependency signals from 10-K filing risk factors.
Every relationship links to the source filing snippet. You can verify the disclosure, check the filing date, and assess how recent the relationship evidence is.
From a single ticker, navigate to its suppliers, their suppliers, and their customers — mapping second-order exposure across the chain.
What makes a supply chain database useful for research
Most supply chain databases aggregate proprietary or estimated data. ChainSifter uses SEC regulatory filings — primary sources that companies are legally required to file accurately. This means every relationship in the database has a cited document, a filing date, and verifiable text evidence. It is the supply chain database built for compliance-grade research.
Coverage and depth
ChainSifter covers public companies filing with the SEC. The database grows continuously as new 10-K and 10-Q filings are ingested. Relationship confidence scores weight recent filings more heavily, so you see which supplier connections are current vs. historical.
ChainSifter provides supply chain relationship data derived from public SEC regulatory filings for research and informational purposes only. This is not investment advice.
