The type of podcast I'd like to listen to is if you got a roundtable of people in various roles (like a roundtable of all technical founders, or a roundtable of all first employees, or a roundtable of all solo founders), and then asked them questions and let them discuss and debate topics, optimally ones submitted by listeners. And perhaps if a subset of those people were particularly good have them on semi-regularly.

There is a woodworking podcast I really like that is 3 woodworkers just chatting with each other about various topics and responding to questions. They all have different perspectives and skills and they often disagree about things, but by listening I get a good idea of the breadth of opinions and viewpoints.

IMO too many startup discussions are very narrow and don't talk about the large breadth of viewpoints that are out there in all sorts of topics. This is especially true if the people doing most of the talking are either VCs or successful founders and essentially are unchallenged by opposing viewpoints.
