It's by Alex Blumberg, former producer on "This American Life" and "Planet Money" by NPR. He recorded the podcast while founding a podcasting company named Gimlet Media and it documents how he got started, chose a name, got investment, found a partner, and various other parts of being a startup. I'd highly recommend the podcast for its amazing story telling and its transparency in including details that most companies would prefer to keep secret.

Startup is a podcast by Alex Blumberg (of This American Life). In the first season, it follows his journey of launching his own startup. Really excellent listening for anyone new to entrepreneurship! https://gimletmedia.com/startup/
