Where the Lead Finder's data comes from

Last updated: September 27, 2026

The business's own website

Phone numbers, contact-form links and published business emails come from the business's own website: its home, contact, about and team pages. Every contact keeps a link to the page where we found it. We follow each site's robots.txt, name ourselves in every request, and wait between requests.

OpenStreetMap

We use OpenStreetMap to discover businesses and their websites. Map data © OpenStreetMap contributors, available under the Open Database License (ODbL): openstreetmap.org/copyright. Contacts we get from OpenStreetMap are marked as such.

Open government data

Public registers and open data published by governments, under their open licences.

What we never use

• LinkedIn or other social networks behind a login
• Guessed email addresses (like first.last@)
• Home addresses
• Personal data that our users upload about their own customers

How we check

Emails: format, the domain's mail server, a throwaway-domain list, and that the email is still on their website. Phones: number format for the country, and that it is listed on their website. We never ask a mail server whether a mailbox exists. We check, we don't guarantee.
