Plaxo.com is the world's leading online address book, hosting over 50 million address book accounts.
In 2002, we set out to solve a difficult problem, creating an address book that doesn't become out-of-date after a few months or years. We've made great strides in this endeavor, powering a unique address book system that imports all your contacts across sources, automatically cleans and updates contact information, and syncs your consistent address book everywhere you need it – all securely backed up in the cloud, so if you ever change phones, get a new computer, or lose your data, you can easily restore all of your important contact information.
However, as new devices, services, and social networks arise, contact information becomes increasingly fragmented and unreliable. At Plaxo, we remain dedicated to evolving and supporting our products and helping our members navigate the shifting communications landscape to ensure that Plaxo truly is and remains, Your address book for life.
Plaxo, Inc. is a subsidiary of Comcast and currently operates three business units in our Silicon Valley offices: Plaxo.com, focused on delivering the vision of a smart online address book; Social Technologies Group, leading social strategy and innovation for Comcast; and Tunerfish, a social discovery engine for TV, movies, and online video.
