Strategic partnership empowers marketers with direct access to premium media inventory
Index Exchange Inc. (Index), one of the world’s largest independent supply-side platforms (SSPs), and dentsu Japan international brands* (DJIB), today announced a partnership. The collaboration leverages Index Marketplaces, a dedicated platform that enables media planners and buyers to activate their digital media buys across streaming TV, display advertising, video, and mobile app, with greater control, efficiency, and transparency.
Through this partnership, DJIB can programmatically trade brand-safe, high-quality media inventory via Index Marketplaces using their preferred demand-side platform (DSP). With direct access to premium inventory, media buyers gain greater control and visibility over ad placements.
“We are thrilled to announce our partnership with Index Exchange, one of the world’s leading SSPs. Index Marketplaces leverages cutting-edge technology to achieve high efficiency,” said Takahiro Horio, CEO of DJIB. “We are excited to curate Index Exchange’s extensive media inventory and integrate it with our unique solutions, providing marketing opportunities to advertisers across various industries in a brand-safe environment.”
Activating Index Marketplaces with deal IDs on the supply side facilitates targeted and safe access at scale, resulting in more matchable audiences and greater reach. This approach simplifies access to tailored inventory and enables precise targeting, allowing marketers to execute campaigns with more confidence, drive meaningful results, and achieve successful outcomes.
This partnership comes as the addressability landscape evolves and media buyers must adapt to the phase-out of third-party cookies. Index Marketplaces assists marketers in strengthening their digital advertising strategies through audience curation, allowing them to reach first and third-party audiences at scale across multiple formats. This enables effective, privacy-focused media strategies for targeted ad placements by seamless audience segmentation.
“We are very pleased to announce our partnership with DJIB, “said Andrew Casale, president and CEO at Index Exchange. “By leveraging the dentsu group’s assets and our secure, high-quality exchange of omnichannel media companies, Marketplaces creates a bridge between marketers’ needs and efficient media inventory. This collaboration will unlock valuable new business opportunities for marketers and media owners alike.”
