Devin van den Berg, Founder and public speaking coach

The art of public speaking

As a professional public speaking coach I have helped over 10.000 people to present confidently and persuasively. One thing I learned over the years is that every great presentation starts with a crystal clear message. Because being a great presenter is not about tricking people into liking your message. 

It’s about knowing what it is you want to say and feeling comfortable enough to present it authentically. After that you can add techniques to make your talk even more impactful. That's the principle behind Verble: a tool that supports you from start to finish, helping you present confidently and persuasively.
