Tool 3: LeadLeap Open Data Search

Free search across hundreds of public government and registry data sources - SEC EDGAR filings, SBA loan data, USPTO patent assignees, FDIC bank directories, FAA aircraft registries, FDA device establishments, international business registries (Australia, Norway, Switzerland), nonprofit filings, federal contract recipients, and more. Cross-referenced through an entity index so the same organization appears across all matching datasets.
