It may not be exactly what you're looking for, but I have a show interviewing people in tech and design. The focus is on longform copy, but I produce a podcast and video with each interview.

It might be worth checking out. I've got interviews with VP of Design, Cap Watkins and Telescope Creator, Sacha Grief in postproduction right now.
I have recently discovered From Scratch [1]. I really like this as it also discuss the person as well as their startup. More human..
