About Jaap Janssen Steenberg
👉 You've got a great idea.
👉 A brilliant product or service.
👉 An offer no one should pass up.
But somehow, you're not getting through. People don’t make time. They don’t take you seriously. Or they nod along… and then do nothing.
That’s a missed opportunity for them—because they don’t realize what they’re missing. But it’s especially frustrating for you. You’ve poured your heart and soul into this, yet you're not seeing the progress you want. At least, not at the pace you'd hoped for.
That’s where ethical persuasion comes in. More specifically: the language that makes it work. Because in the end, it all comes down to choosing the right words.
And that’s where I come in. As a Cialdini® Institute Licensed Trainer, Certified Online Influence Coach, and award-winning copywriter, I train professionals like you to find the right words at the right moment—whether you're leading, communicating, marketing, presenting, or persuading in any other part of your business.
Want to explore what that could look like for you?
👉 So people make time?
👉 So they take you seriously?
👉 So they nod along... and take action?
Just a quick note: because of my ongoing work with Dr. Cialdini and Bas Wouters, I take on only a limited number of new projects.
Work for a nonprofit? Here's something you should know: I offer one free training session each month to support nonprofit organizations.
