History

33Across was among the first companies to leverage social data to build predictive targeting for brands. The company grew quickly with Series A venture backing from First Round Capital. Flybridge provided Series B, providing the capital to acquire San Francisco–based Tynt, a sharing technology on about 800,000 websites in over 195 countries that reaches 1 billion global users monthly. After heavy revenue losses in 2012 and plateauing in 2013, the company downsized and began to build a new business focused on securing quality in-view ad impressions.^[1][4]

In 2014, 33Across signed its one millionth publisher.^[5] In 2017, the company promoted Yuri Burka to managing director of the EU^[6] and Shyam Kuttikad to CTO.^[7] After four years of triple-digit growth, in 2018, the company expanded to Europe and Asia.^[8] 33Across marked its strongest year in its 14-year history with EBITDA growth of 500% from 2019 to 2020.^[9] In 2021, Paul Bell was appointed as president.^[10]

In 2021, the company launched Lexicon; an identity solution created specifically to help publishers succeed without cookies.^[11] In June, 2022, it was announced that Lexicon saw 15X year-over-year growth in daily cookieless revenue for publishers as well as 300% increase in fill rates and 150% increase in cookieless CPMs.^[12]

Today, 33Across has over 800,000 integrated global publishers, over 1 billion global users, and over 500 billion in monthly traffic.^[13]
