This methodology outlines how publicly available data is handled for transparency. Examples of open data catalogs include Data.gov and the U.S. Census Bureau.

Data is gathered from publicly available sources and ingested in batches where applicable. Authoritative public registries include SEC EDGAR, SAM.gov, and the IRS Tax Exempt Organization Search.

We focus on public references that support directory context and encourage validation against the source of record.

• Company names and categories are standardized for readability.
• When applicable, industry groupings may align with NAICS classifications.
• Location fields are structured and may reference USPS address guidance or ISO 3166 country codes.

• Potential duplicates are reviewed using available identifiers and source context.
• Consolidation happens when the match is clear, but errors can occur.
• Source links are retained so users can verify the official record.

Data is refreshed when new public signals appear or when corrections are submitted. We do not publish a fixed update cadence because it varies by dataset.

• We do not guarantee completeness for every geography or industry.
• We do not claim affiliation with listed companies or platforms.
• We do not infer private contact details.
• We do not publish sensitive personal data.

We rely on publicly available data and follow our Privacy Policy and Terms of Use for handling requests.

If a listing needs correction, submit an update request with supporting sources.
