ID5 provides a privacy-first identity infrastructure that enables addressable and measurable advertising while protecting user data. Its solutions enable user recognition across media properties and devices and have been adopted by thousands of publishers, advertisers and ad-tech platforms, including Havas Media, New York Post, M6 Publicité, Adobe Advertising platform, OpenX and Eyeota. The company says its identifier supports almost 50% of online advertising transactions, reflecting broad adoption in cookieless environments. Created in 2017, ID5 emphasizes transparent, scalable and GDPR-aware technology to help publishers monetize audiences and advertisers run effective, measurable campaigns. ID5 raised a $20 million Series B to expand its privacy-first advertising identity service and accelerate product innovation ahead of the anticipated end of cookies in 2024. The company plans to continue innovating and expanding its mission to support the entire advertising ecosystem across all channels.
