Crunchbase's public data comes from multiple channels - our active community of contributors, publicly available sources, or various data partners. Due to our crowdsourced nature, the information on profiles for individuals, organizations, or institutions can come from more than one source.
While all of this data pertains to the information publicly displayed on our site, Crunchbase also receives personal information through (1) details volunteered by our users and (2) information recorded when users interact with our services.
Our community of users opt into registering for accounts in order to make edits to the site. To ensure the legitimacy of user contributions, we ask that users authenticate their user accounts via Facebook, Twitter, or LinkedIn before they can make any edits.
