Mumbrella360 has unveiled global marketing leadership expert Thomas Barta as a keynote speaker for this year’s event, taking place from 26–28 May 2026, where he will present on the “Catalyst” theme that underpins this year’s conference.

Drawing on his latest research and insights from the Marketing Leadership Masterclass, Barta’s keynote will give delegates a framework to close the gap between knowing what needs to change and actually making it happen.

Built around the idea that “companies don’t create the future people do”, the session will explore how breakthroughs are driven by individuals inside organisations.

Flying in from Germany, Barta, a former McKinsey partner, will discuss how marketers can move beyond seeking permission to leading transformation, and evolve from marketing experts into true catalysts for change.

Plus, global speakers already confirmed on the lineup include renowned New York-based strategist and CEO of Sweathead, Mark Pollard; Amsterdam-based Ebiquity CEO, Ruben Schreurs; San Francisco-based head of product marketing for Roblox, Maura Tuohy, and Sherilyn Shackell, the founder and CEO of The Marketing Academy will be jetting in from London. Check out the growing program and stay tuned for more content announcements very soon.
