About InfoSum

WPP bought InfoSum in April 2025 (for about $150 million, its postings say) and runs it as the data layer under WPP Open, so its sellers work both WPP's own agency teams and outside brands, publishers and data providers. The business is moving from flat platform fees to usage-based revenue, which puts most of the open sales seats after the signature: customer success managers carry books of brands, publishers and data providers (16 to 20 accounts on the New York role), push usage fees and renewals and upsell platform fees, under a New York director who manages the CSMs and associates, keeps key clients personally and steps in when a portfolio falls short of its usage or revenue target. Solutions engineers take the pre-sale scoping and proofs of concept alongside the sales team, then own implementations on GCP, Snowflake, AWS, Azure and Databricks for partners such as Disney, NBCU, Netflix, Roku and Walmart, writing SQL and Python as they go. Four of the six sales openings are in New York (a CSM, the director and two solutions engineers), with a customer success manager in Toronto and a solutions engineer in Australia, all hybrid at about four office days a week. New-business selling in Europe sits with separate market lead roles in Amsterdam, Düsseldorf and Copenhagen that sell across the WPP network and to clients directly.
