Otto Advertising Launches In-House Demand-Side Platform

Executive Signal Summary

Otto Advertising, the retail-media arm of the Otto Group, has launched its own Demand-Side Platform (DSP). The self-developed platform enables advertisers and media agencies to buy digital inventory across channels and publishers in both self-service and managed-service modes. While primarily targeting brands within the Otto ecosystem, it is also open to non-endemic advertisers. The DSP relies on exclusive first-party data from more than 31 million active Otto Group user accounts to enable data-driven targeting on premium websites and digital-out-of-home screens, with supply to grow. The infrastructure is built in-house, avoiding external tech providers and third-party data to enhance transparency and potential cost efficiency on both buy and sell sides. Mediaplus was the first agency to test the platform during an autumn campaign for a tourism client, reporting precise targeting and strong results. The offering combines self-service and managed-service options, with a roadmap to add conversion-focused self-service features next year.

CMO Tenure Drops 35% Since 2010, Study Finds

A study of 13,000 U.S. marketing professionals reveals that median CMO tenure has declined by 35% since 2010, from four years to 2.6 years for those starting after 2022. The survey, conducted by Findem and CMO Huddles, highlights that only 36% of Fortune 500 companies now use the CMO title, a significant drop from 55% in 2024. CMOs often report to someone other than the CEO, and marketing spend as a share of sales has fallen to 7.8% from 11.2% in 2018. Short tenures lead to inconsistent direction and frequent agency pitches, with agency-client relationships averaging just 3.7 years. Experts attribute the trend to misaligned expectations and reduced CMO influence in the boardroom.
