Supply chain tracker for public company relationship changes
ChainSifter tracks supply chain relationships for public companies as they evolve through SEC filings. When a company adds a new named supplier, discloses a concentration risk change, or updates its key vendor relationships in a 10-K or 10-Q, ChainSifter captures and indexes the change.
New suppliers added, existing ones dropped, or concentration disclosures updated — tracked across each new filing cycle.

How supply chain tracking works in ChainSifter
SEC filing ingestion runs continuously. When a new 10-K, 10-Q, or 8-K is filed, ChainSifter extracts named entities — suppliers, customers, and partners — and updates the affected chain pages. The result is a supply chain tracker that reflects the most current disclosed relationships, not static reports updated annually.
Use cases for supply chain tracking
- Monitoring single-source dependencies for portfolio companies
- Identifying public-company exposure to a geographic region or manufacturer
- Researching competitive supply chain positioning before earnings
- Finding secondary exposure to a major company through its named vendors
