Sourcing
LeadQuasar’s B2B records are aggregated from public and commercially licensed sources: business listings, company websites and professional data providers. They are business contact details — company names, business email addresses, business phone numbers and roles — not consumer or private data. The database is US-focused: about 7.4 million records are in the United States, most of the remainder in Canada, and coverage is thin outside North America.
Scoring every record
Each record carries a deterministic 0–100 quality score and a data tier — Lean, Standard, Connected, Verified or Premium — computed from what the record actually contains: a website, a phone number, an email and that email’s verification status, a LinkedIn profile, and firmographics such as company, industry, team size and job title. Both are shown on a lead while it is still locked, so you can tell a verified direct email from a switchboard number before you unlock anything.
How the figures are counted
Counts on this site are read from the live database, not estimated. Industry pages merge spelling variants of the same trade into one industry and are only published once an industry holds at least 150 records; city pages need 250. Where a figure is a floor rather than a census — for example a business type with no category of its own, matched by company name — the tools say so.
Removal and your own data
Anyone listed can ask to be removed by emailing support@leadquasar.com; the record is deleted and suppressed from future imports. LeadQuasar does not sell customer data and does not add the people customers contact to its database. The security and data practices page has the detail.
