We saw last Friday that Tylenol is eager to let you know they’re watching your every move. The folks at Acxiom-owned LiveRamp are more discreet even though their ambition is broader: nothing less than a “universal, people-based identifier” to track people across all devices in all media. They’ve just made their IdentityLink IDs available to ad agencies, completing a plan that has already made them available to brands, technology platforms, data owners, and publishers.

And still more about money: companies will spend $4.7 billion on customer journey analytics software and services in 2017, says palindromically-named Markets and Markets. They expect the industry to reach $12.2 billion by 2022. Before you faint at the thought of all that mapping software, read the fine print: the estimate includes all customer segmentation, targeting, behavior analysis, brand management, campaign management and product management systems. Details will cost you $5,650.

GrowthLoop will use TransUnion identity data to improve U.S. consumer match rates on client files sent to advertising media such as Facebook and Google Ads.  The data should also help clients to find matches among records within their files, building more accurate customer profiles.  GrowthLoop calls itself a “composable CDP”, meaning it works with data assembled in external data warehouses.
