Brian Wieser, CFA, CEO and Principal
I am, at heart, an analyst. But not an "industry analyst" nor purely a "financial analyst." I'm more strategically oriented than most people who have worked on Wall Street and more conscious of capital markets issues and investor thinking than most who focus on strategy.
My background includes extensive experience in both industries. I was a banker at Lehman Brothers (covering the media and telecom industries), an Institutional Investor-award winning sell-side analyst at both Deutsche Bank (covering cable and satellite) and Pivotal Research (covering technology, media and services businesses). I also worked a senior executive at two of the world's four largest advertising agency groups, Interpublic and WPP. In addition, I was CMO for Simulmedia, a leading provider of advanced TV solutions.
Luke Stillman, CFA, Managing Director
I analyze how money moves through the advertising economy to bring clarity to a changing industry. My work focuses on decisions, reading budgets and balance sheets rather than narratives shaped by PR.
My analysis is driven by data, but shaped by an understanding of how advertisers, agencies, platforms, and investors make decisions under uncertainty.
My background spans Wall Street and global advertising agencies. On Wall Street, I worked across both the sell side and buy side, informing equity and fixed income investment decisions. In advertising, I spent more than a decade at Interpublic’s MAGNA Intelligence unit, where I established industry benchmarks for digital and programmatic advertising, led forecasting for more than $10 billion in annual client billings, and built the tools used for upfront negotiations, measurement, and strategy.

Audiences, attention, and ad dollars are always moving. I help media, advertising, and technology companies understand where they’re going and what those shifts mean for the business, so they can grow through change.
At Madison & Wall I lead Client Development & Solutions, working with senior leaders on revenue strategy, go-to-market planning, and advanced advertising.
Most recently I was CRO and CMO at Corus Entertainment, with more than 20 years in media, advertising, and revenue leadership. I oversaw more than $1.5 billion in annual revenue across ad sales, digital content distribution, and client integration. There I built the cross-functional teams that helped the business respond to major shifts in consumer behavior, media consumption, and ad technology.
Outside of work, I'm usually with my wife and two daughters, cooking, or in the middle of a DIY project.
Heather McAdam, Head of Operations
Throughout my career I’ve been an operator who thinks like a finance executive, working where revenue strategy meets the numbers. Turning pricing, inventory and forecasting into processes that leadership teams can actually run a business on.
My work is grounded in understanding how advertising revenue is really made: ratings projections, pricing decisions and inventory yield, not just top-line results. That perspective comes from years of building budgets and forecasts and presenting them to executive teams and boards.
Broadcast media, consumer packaged goods and financial services have all been part of my career. At Corus Entertainment, I led revenue management for $1.5 billion in advertising and subscriber revenue across television, radio and digital. Before that, I was Lead Financial Officer for BMO Financial Group’s corporate functions, overseeing $2.3 billion in spend. Earlier, I held senior FP&A roles at Del Monte Canada and at Kraft Canada.
James McDonald, Managing Director Global Markets
At Madison & Wall, I lead international research and product development, drawing on a long career tracking advertising and media trends around the world.
On the technical side, I hold qualifications in data science, statistics and machine learning, with a focus on forecasting and large language models.
My career began in broadcast media as a TV analyst in London, before I moved to Los Angeles to work directly with the studios. In 2013 I joined WARC, where over 13 years I rebuilt the WARC Media product into a market-leading, multi-million-dollar international business. I moved to Toronto in 2026 to join Madison & Wall.
