About Us

33Across has over 15 years of experience building identity resolution technology, programmatic monetization, and audience segmentation through big data and a global first-party publisher foundation. Future-proofing the industry's addressable infrastructure, 33Across provides direct access to critical signals that power privacy-safe programmatic transactions for supply-side platforms, demand-side platforms, publishers, data companies, agencies, and everything in between.

The Lexicon Story

We set out to build a browser-agnostic solution that would power the open web and help publishers monetize all of their content. Lexicon allows the internet to operate the way it was always intended; engaging and respectful to consumers while effective for publishers and advertisers.

What's a Lexicon?

In the most simple terms, a lexicon is the vocabulary of a person, language, or branch of knowledge. We believe that in order to support the open internet, the digital advertising industry needs a browser-agnostic lexicon to fairly target, transact, and measure that falls within the bounds of privacy. 33Across Lexicon creates the first addressable infrastructure for the programmatic ecosystem that’s interoperable, agile, and more efficient than the cookie. ​
