The SaaS Podcast by Omer Khan has some solid technical interviews including lots on growth and matketing with solo devs and small teams who are actually serious and not just grifting and wrapping apis with no-code solutions.

The World Of DaaS by Auren Hoffman has some decent episodes. These tend to be interviews with more established entrepreneurs but lots of bootstrapping/ early growth stories from devs/teams when they were much smaller.

Thanks!
