Where It All Connects
Political & Public Affairs
Cross Screen Media was built from political DNA. Originally spun out of a leading campaign tech firm, the company has remained deeply rooted in supporting the public affairs and political ecosystem—from presidential campaigns to hyperlocal land use initiatives.
The work spans three strategic objectives: influencing policy, protecting corporate reputation, and driving behavioral change. Whether supporting national trade associations, advocacy groups, or public health initiatives, the team specializes in nuanced audience targeting, message sequencing, and outcome measurement at every level of government.
Through its proprietary data infrastructure, the platform enables legislative district-level targeting, influencer audience reach (journalists, staffers, lawmakers), and regularly updated issue models. These models help campaigns precisely target audiences based on ideology, turnout likelihood, or support for topics like immigration, education, technology, or healthcare.
Chauncey’s leadership in this vertical focuses on navigating the complexity of modern public affairs—balancing reach and frequency, integrating emerging channels like SMS/MMS, and bridging the gap between storytelling and strategic outcomes.
Convergent TV Advertising
Chauncey has been at the forefront of solving one of media’s hardest problems: how to unify video advertising across screens. At Cross Screen Media, convergent TV means planning, activating, and measuring campaigns that span broadcast, cable, CTV, mobile, and desktop—all tied to a single audience strategy.
The platform is engineered for efficiency. By bypassing traditional DSPs and working directly with supply platforms like Magnite, Pubmatic, and Yahoo, Cross Screen reduces ad tech fees and maximizes budget-to-impression performance. Campaigns are also verified with partners like Double Verify and Moat, keeping fraud rates below 1%.
What sets the platform apart is its measurement: deduplicated, cross-platform reach and frequency reporting that reveals not just who was reached, but where, when, and how often. This data enables smarter budgeting, avoids media waste, and offers insight into competitive spend patterns across both linear and CTV channels.
Under Chauncey's direction, the company has turned convergent video from a buzzword into a working system—giving political campaigns and brands a real way to plan and measure their media holistically.
AI-First Data Management
At the heart of everything is data—and Cross Screen’s data operation is built for scale, speed, and precision. The foundation is an AI-first identity infrastructure, anchored by LiveRamp’s ID spine and enhanced with voter files, consumer data, and ACR viewership insights from 20M+ U.S. households.
Chauncey has led efforts to unify planning, targeting, and measurement within a single data ecosystem. The company’s tools allow users to define audiences using Boolean logic, pull dynamic segments based on exposure or engagement, and close the loop post-campaign by identifying unreachable targets for follow-up via email, SMS, or direct mail.
Quarterly-updated political and issue models ensure real-time relevance, while the system’s ACR integrations enable ad-level exposure targeting, competitive analysis, and cross-screen retargeting.
This is not data for data’s sake—it’s infrastructure designed to power media strategy, adapt in real time, and enable precision without sacrificing scale. That’s the AI-first advantage Chauncey is building into every layer of Cross Screen Media.
