Adapex Activates Universal ID From ID5

March 31, 2021

New York, March 2021 – Adapex is excited to announce that we have partnered with ID5 to bring our publisher partners a universal ID solution to enable privacy-compliant user IDs to power data-driven advertising.  User-level data has proven to be a strong driver of campaign performance. Data-driven strategies generate higher yields for both publishers and brands.

“We are pleased to work with ID5 as we look to increase awareness, adoption, and ultimately the scale, of sustainable cookie-alternative solutions,” said Debra Fleenor, Founder and CEO, Adapex.  “ We’re eager to work with other industry innovators to make the ecosystem stronger and implement a better alternative to cookies that centers on consumer privacy and control.” 

“The collaboration with AdApex enables more publishers to use ID5 Universal ID to improve the monetization of their Safari and Firefox audiences and to be better prepared for the demise of the third-party cookie, “adds Mathieu Roche, Co-founder & CEO, ID5. “By benefitting from enhanced and privacy-compliant identification capabilities, media owners can stay competitive in the cookieless future as they continue to attract advertising budgets, and provide consumers with control and transparency over their data privacy choices.”

Improving the consumer, publisher, and advertiser connection is top of mind for Adapex and they have been involved in working toward solutions through involvement in the IAB Global Privacy and Rearc Accountability Working Groups.  “Our goal is to drive revenue for our publisher partners while improving the user experience,” adds Fleenor.

Adapex is hosting a webinar later in April to bring together a representative group of thought leaders in the privacy conversation.  ID5 will be joining the discussion to share their perspective on privacy-first advertising for publishers and brands and the future of identity in general.  This webinar will bring publishers key insight into how advertiser dollars are following identity solutions. Stay tuned for the agenda and further details.
