33Across rebrands as WealthStage(TM), launching new digital advertising platform built for financial services.

33Across rebrands as WealthStage(TM), launching new digital advertising platform built for financial services. WealthStage unifies trusted customer intelligence with wealth, lifestage, and real-time signals to help marketers engage with the right households to drive tangible results. NEW YORK, Sept. 16, 2026 (GLOBE NEWSWIRE) - 33Across today announced its rebrand to WealthStage(TM), a digital advertising platform built for financial services marketers navigating a rapidly changing technology, consumer, and wealth landscape. Financial services brands operate with unique requirements for data quality, trust, compliance, and performance. WealthStage connects a brand's first-party data with authoritative wealth and lifestage data, intent indicators, and real-time signals, so marketers can execute media with greater results. From helping retail banks reach recent graduates entering a new financial stage to enabling digital trading platforms to identify high-net-worth households demonstrating investment intent, WealthStage allows marketers to engage with the right households when interest, capacity, and opportunity align. The company launch comes as an estimated $124 trillion in wealth is expected to change hands through 2048, reshaping how financial institutions compete for and build relationships with consumers. At the same time, younger households are consuming media, managing money, and interacting with brands differently than previous generations. "U.S. households no longer follow a traditional linear path, and, given our category experience and the economic shifts happening in household wealth, we see an unmet need for a solution built around how financial services marketers acquire their next customer," said Eric Wheeler, CEO of WealthStage. "WealthStage helps marketers engage with today's unique households using validated data and AI to drive better outcomes." From Customer Intelligence to Smarter Media Activation WealthStage builds on 33Across' 15-year data ecosystem and digital advertising financial services expertise, including partnerships and integrations with leading wealth and lifestage data providers to activate across digital media. These capabilities provide a foundation that WealthStage is now extending specifically for the needs of financial services marketers. At the center is the WealthStage Engine(TM), which applies AI across persistent data sets and real-time signals to help marketers better understand a household's economic capacity, life stage, and intent. The engine continuously learns from endemic signals and performance feedback signals to optimize media toward measurable real-world business outcomes like new accounts, assets under management, or customer lifetime value. "Financial services marketers need a better way to connect the customer intelligence they already have with how they reach consumers across digital media. WealthStage brings those pieces together, helping marketers build a clearer view of their audiences and activate against that intelligence to drive business results," said Francesco Lagutaine, former CMO of USAA & M&T Bank. As part of the rebrand, 33Across will continue to operate and expand its existing data and publisher businesses as a division of WealthStage, while WealthStage becomes the company's brand for its growing financial services offering. About WealthStage WealthStage(TM) is an advertising platform built for financial services marketers. The platform unifies first-party data with trusted wealth, lifestage, and real-time signals to activate smarter media and drive measurable business outcomes. Powered by the WealthStage Engine, WealthStage uses AI to focus on households with ideal interest and capacity to deliver better efficiency. Learn more at WealthStage.ai.

Retail Advertisers Double Cookieless Share Of Voice Growth Yearly According To 33Across Q4 2023 Programmatic Cookie Alternative Trends Report

Advertisers Still Heavily Rely on Third-Party Cookies for Programmatic; Publishers Increased Their QoQ Cookieless Revenue Across Most Categories in Q433Across, an addressable infrastructure designed for the open web, today announced findings from its latest “Q4 Programmatic Cookie Alternative Trends Report.” In creating this new report, 33Across examined programmatic transactions on its exchange to understand cookie alternative and third-party cookie trends among buyers and sellers in Q4 2023.Current Trends in Third-Party Cookie Deprecation2023 was quite a turbulent year for digital advertising as the industry experienced economic weakness, layoffs, and confirmation of Google’s third-party cookie deprecation timeline. However, during the second half of the year, positive economic indicators like stable interest rates, increased consumer spending, and continued job growth curbed the fear of a US recession.Google’s Privacy Sandbox has recently come under scrutiny in a report by the IAB Tech Lab, revealing gaps in the process of purchasing, selling, delivering, and measuring digital ads following the decline of third-party cookies. While Google’s Privacy Sandbox aims to address some of these gaps, the IAB Tech Lab has highlighted additional areas needing attention. Google, however, has disputed the report, claiming it contains “many inaccuracies” and overlooks the broader objective of the Privacy Sandbox: enhancing user privacy while maintaining effective digital advertising.Marketing Technology News: 10th Annual Customer Engagement Study Reveals Generational Shifts in How IT Decision Makers Engage with Technology Content and Advertising33Across Exchange InsightsIn contrast to the restraint we saw from marketers during the fourth quarter of 2022, the 33Across Exchange had considerable growth in Q4 2023. On average, advertisers grew their cookie alternative investment quarter-over-quarter (QOQ) by 13% in Q4, increasing their cookie alternative share of voice (SOV) by an average of 9%. Since Google announced it would begin removing third-party cookies on 1% of Chrome users, programmatic buyers have pushed to test alternative identifiers and solutions
