The first place to connect.

Cardbox reimagines the address book as a social network—in the purest sense. Connect and stay connected in a central place, without all the noise.

Everyone manages contact information, but the process is dull, tedious, and hasn’t changed since the first smartphones. Contacts are usually made on the spot, and you always end up with incomplete, outdated, and duplicate contacts. Cardbox turns the concept of contacts on its head.

How does it work?

Create Your Card

Take control of your digital identity.

You only manage the contact information on your own card. From your personal details to your social media presence, and even the photo they see when you call or text; you are now in control.

New phone number or email address? No problem. Simply edit your card, and all changes are instantly pushed to the address books of your connections.

Build Your Network

Stay in touch with just a touch.

Exchanging contact information is fast and easy. Look someone up by their name, link, or using Nearby, and request to connect. When they accept, you subscribe to each other’s contact information.

Cardbox puts privacy first. The information on your card is encrypted, and only shared with your connections—not advertisers or data brokers.
