Jarrod Martin

Martin is the operator IPG installed in June 2024 to fuse two adjacent assets that had been run as separate properties: Acxiom — the people-based identity and data infrastructure unit IPG bought for $2.3 billion in 2018 — and KINESSO, the performance, data, and tech engine inside IPG Mediabrands. The unification consolidated Salesforce cloud services (including the RafterOne practice acquired in October 2022) under Acxiom and put the data engineering, identity resolution, and AI investments under one P&L.

He had been at IPG Mediabrands for 11 years by then, with a steady data-and-analytics arc: a specialist analytics unit he started in Australia in 2013, a move to New York to run Mediabrands Insights, five years as Global COO of Initiative, the Reprise Digital CEO seat in April 2022, then KINESSO Global CEO when Reprise and Matterkind were folded in during September 2023.

His relevance to streaming and CTV buyers sits in two places. First, Acxiom is the spine under IPG (now Omnicom) media buys for identity resolution and audience targeting across CTV inventory — meaningfully more so as the addressable layer fragments. Second, the Omnicom–IPG merger that closed November 26, 2025 made Acxiom the largest single data asset inside the new combined holdco, and how Omnicom integrates and monetizes that asset is one of the defining questions of the 2026 ad-tech landscape.
