Mantis Joins Index Marketplaces, Expanding Access to AI-Powered Brand Safety and Contextual Targeting 

The integration brings Mantis’ certified audience segments directly into Index Exchange’s Data Vendor Ecosystem 

Mantis, a leading provider of contextual advertising solutions with built-in brand safety and suitability, today announced it is now using Index Marketplaces to deliver its certified brand safety and contextual audience segments directly to media owners and platforms. This integration makes Mantis’ solutions natively available within Index’s Data Vendor Ecosystem, enabling media buyers and Marketplace partners to seamlessly activate these across premium publisher inventory, bringing curated supply and smarter decisioning to the forefront.  

Index Marketplace partners now have streamlined access to Mantis certified audience segments for the first time, removing the need for advertisers and agencies to request data on a one-to-one basis. Buyers can now also efficiently activate Mantis brand safety and contextual segments directly on the sell side within Index Marketplaces, benefiting from scalable precision targeting while ensuring campaigns run in safe and suitable environments. 

 This integration reflects a shared commitment to transparency and efficiency across the ecosystem, reducing unnecessary fees in the supply chain and ensuring greater value flows between media owners and buyers. 
 
The collaboration is led by Fiona Salmon, Managing Director at Mantis, and Cadi Jones, SVP EMEA at Index Exchange, both of whom champion integrity and innovation in the digital advertising space, making this partnership a natural step in driving meaningful change across the industry. 

“Partnering with Index Exchange marks an important milestone for us in broadening access to Mantis intelligence across the programmatic ecosystem,” said Fiona Salmon, Managing Director at Mantis. “By making our brand safety and contextual solutions available natively within Index’s Data Vendor Ecosystem, we’re simplifying activation for buyers and driving stronger outcomes for advertisers and publishers alike.” 

Cadi Jones, SVP EMEA, Index Exchange commented, “Index Exchange and Mantis share a commitment to driving positive change in the ecosystem, reducing friction, increasing transparency, and simplifying access to premium publisher inventory. By integrating Mantis’ technology directly into our exchange, our partnership will bring the robust benefits of its advanced solutions to our Marketplace partners and buyers.”
