About SPEACHERS.COM

We are discontent with current speaker marketplaces.

Responses are slow, connections are unpersonal, and the speakers leave immediately after their talk.

No more.

Founded by Lukas Hefti, SPEACHERS.COM manages speakers our team knows personally, are inspiring on stage, and easy to work with.
