Adnami Joins Index Exchange’s Data Vendor Ecosystem, Making Attention Data Available Across Index Marketplaces

Adnami’s proprietary attention data is now available directly within Index Marketplaces, giving media buyers and curators who already work with Index Exchange a new way to activate attention signals.

Adnami, the attention-first AdTech company, and Index Exchange (Index), a globally trusted independent supply-side platform powering intelligent decisioning, today announced that Adnami is joining Index’s Data Vendor Ecosystem. The move makes Adnami’s proprietary attention data available as data segments within Index Marketplaces, giving media buyers and curators a new way to bring attention into how they build and activate deals.

This integration further strengthens the partnership between the two companies, following the June 2026 launch of Adnami’s Agentic Supply Optimisation via Index’s SSP, which paired Adnami’s attention data and high impact formats with Index’s reach across premium publishers.

The Adnami segments are powered by Sonar, its proprietary attention measurement technology, which uses a single tag to measure attention across high impact and standard display advertising at ad server and DSP level. As buyers look beyond viewability, attention has become one of the clearest indicators of the upper-funnel value their media spend delivers. This integration gives media buyers and Index Marketplace partners a direct route to activating attention data, enabling more efficient campaigns and stronger outcomes.

Buyers who already work with Index Exchange can now activate Adnami’s attention segments directly through their existing relationship, with no separate contract, billing or integration required.

The addition reflects a broader shift in how buyers are putting attention to work, not only within Adnami’s own high impact formats and Supply Agents, but as a standalone signal available across the wider programmatic ecosystem. For Adnami, joining the Index Data Vendor Ecosystem extends its attention-first approach to a broader set of Index Marketplace partners; for Index, it adds a further premium data source for curators and marketers building data-driven deals.

“Attention is becoming one of the clearest ways to judge whether an impression was actually seen. Joining the Index Data Vendor Ecosystem means more buyers and curators can put our attention data to work, directly inside a marketplace many of them already use. It’s a straightforward way to bring attention into more deals, and a natural next step in our partnership with Index Exchange,” Simon Kvist, CEO, Adnami.

“The Data Vendor Ecosystem is about giving our partners choice in the data they build with,” said John Tigg, SVP of buyer development, EMEA at Index Exchange. “Adnami’s attention data adds a premium, attention-first signal to that mix, so curators and marketers in Index Marketplaces can package supply around the outcomes that matter most to their marketers.”
