Might I recommend: http://www.startupsfortherestofus.com/ as an excellent podcast for this field. As the intro of each episode states:

"Welcome to Startups for the Rest of Us, the podcast that helps developers, designers and entrepreneurs be awesome at launching software products, whether you’ve built your first product or you’re just thinking about it. And we’re here to share our experiences to help you avoid the same mistakes we’ve made."
