DataSift also assembles data about people, in its case taking feeds from social media sites. Some is anonymized and some is linked to individuals, depending on what the site owner allows. DataSift just set up a feed of anonymized LinkedIn data to crystal.io, an artificial intelligence-powered “virtual advisor” promises insightful answers to marketers’ questions. To be clear (get it?), crystal.io works only with aggregated data, so it can’t tell you what Dad wants for Father’s Day.
