Tamsen Webster Speaking Topics

  • Say What They Can't Unhear: How To Inspire Change That Lasts

    In a world of constant change, how can leaders inspire transformations that truly endure? Tamsen Webster, acclaimed speaker and author of "Say What They Can't Unhear: The 9 Principles of Lasting Change," presents a groundbreaking approach to creating lasting shifts in organizations, markets, and individual lives.

    Drawing from over 30 years of experience in message design and change communications, Webster challenges conventional wisdom about change management. She reveals why traditional methods often fall short and introduces a powerful new framework for inspiring change that stands the test of time.

    Whether you're navigating a corporate pivot, launching a disruptive product, or seeking personal growth, this keynote will equip you with the tools to not just initiate change, but to make it last. Learn how to turn a momentary "yes" into an enduring commitment with ideas that resonate so strongly, they become impossible to "unhear."

    Key Takeaways:

    Understand why change is a reaction, not just an action, and how to align your approach accordingly

    Learn to craft a case for change that resonates with your audience's existing beliefs and identity

    Discover strategies to overcome resistance without relying on pain or pressure

    Master the art of turning short-term agreement into long-term commitment

  • The Logic of Emotion: How to Make Inaction Impossible

    You may have noticed a problem with the age-old “problem/solution” formula for driving action from your messages and marketing: it doesn’t always work! That’s a big issue when your job, and maybe even your business, depends on your content converting customers and clients.

    Unfortunately, presenting only the audience’s problem and your solution misses an important fact about them: your audiences aren’t rational decision-makers, they’re rataionalIZING decision-makers. They tell themselves stories to justify what they do. That means your content needs more than just a problem and a solution, it needs to create a moment of truth in your audience’s mind—a realization that makes inaction impossible.

    In this keynote, learn to use a simple structure that creates both the logical and emotional change you need for content that creates long-term change.
