Crowdsourcing builds your contact list
straight from your network
Dubb helps you leverage your network, creating a mobile rolodex of contacts. When you become friends with someone on Dubb their contact list is aggregated with yours. No need to call your friends anymore to see if they have someone's contact, simply look into your network, and request the contact!
We keep privacy in mind, therefore if you have any contacts that you do not wish other people to see, simply make them invisible and hide them from the Network. No contact information (numbers, e-mails, address, etc) in your phonebook is shown unless you accept the request to share it with your Dubb friend.
