Our Data Sources

Every time you perform a search in Lusha, the contact and company data that you receive is updated.

Lusha’s proprietary algorithm cross-checks data from multiple sources and combines numerous data-points, to create one business contact or company profile.


We use the following information sources:

Lusha Community’s Data Contribution

The Lusha community are members that have decided to share their contact details under the terms of the Lusha Community Program. Community members are those who volunteer to contribute their data to Lusha’s community from their own social business network. Community members share email headers and signature blocks from their business email with Lusha. This is information that would be found on a business card, including data attributes like names, email addresses, and phone numbers.

We receive contact details from End-Users of our affiliates, i.e. subsidiaries, parent companies, and other corporate entities under common ownership.

Where Lusha End Users provide us access to their email account, for the purposes of using our email composing features, we obtain data using Google’s or Microsoft’s APIs.

Third Parties

We license information from business partners who own established and trustworthy directories. Our partners utilize the most cutting-edge AI and machine learning technology to collect data from public records, publicly available information, and business directories.

We verify each vendor’s data to ensure its accuracy, before and during the engagement.

  • We review each vendor’s security, as well as the security of the data transfer.
  • We sign legal documentation with each vendor to ensure that data provided to us is legal, and compliant with all data privacy laws, including GDPR and CCPA.
  • We are always working to ensure our data is compliant, and update all contracts on an as-needed basis, to stay aligned with any applicable laws and regulations.
