Instead of a typical powerpoint presentation, Roman performs a customized collection of stories from 99% Invisible live, complete with music and sound clips. It's very cool. He got a standing ovation on the TED main stage in 2015, he's been the host and MC of the both the national AIGA and AIA conferences, a keynote speaker at numerous events, and a lunchtime storyteller at companies around the world. Mars gets booked up over a year in advance, so get in touch ASAP if you'd like him to present at your event. 

“Roman Mars’s keynote was an unorthodox, memorable, and profoundly engaging event: rather than delivering a conventional speech, Roman used audio samples to create a completely new experience, guiding our attendees into considering new perspectives about the built environment. Our attendees haven’t been able to stop talking about it. Roman has set a high bar for our Convention that I’m sure we’ll struggle to top.”
