“Matt’s stellar track record with publishers throughout his career will be a critical resource for 33Across as we continue our mission to help publishers navigate the ever-changing landscape of cookieless, monetization, and addressability,” said Eric Wheeler, CEO and Co-Founder, 33Across. “I look forward to Matt’s contributions in helping 33Across continue to grow and execute ahead of the market.”

“Eric and the team at 33Across have built an amazing company that has constantly demonstrated an ability to lean into change and embrace it. Lexicon’s differentiated approach to solving cookieless monetization helps every publisher earn the fair value for their content independent of the browser,” said Gillis.

Gillis’ appointment comes on the heels of the company’s campaign to help publishers navigate the cookieless world.

Then recently, 33Across announced a new multi-year strategic partnership with Google Cloud that will allow 33Across to significantly enhance its overall operations by increasing traffic, reducing latency, and providing limitless scalability.
