We have partnerships with other data companies and we also use the social network APIs. Everything is stored in a graph and to make the connections between phone, emails and identities we've created algorithms to compare contact information. For this we use signals like name similarity, location, friends in common and many others. All of this is indexed in realtime and when you do a query to our API you get the most up-to-date data.
