Hi, I’m Jason DeFillippo.

I’m a full-time podcast producer, host, and editor, and I’ve been podcasting professionally for over ten years.

I'm the co-host of Grumpy Old Geeks, one of the oldest tech news podcasts.

I was a web developer for 22 years.

I wanted to be a photographer when I grew up.

Jason is one of the best producers in podcasting, hands-down. The difference between a show that sounds good and a show that sounds great is whatever magic he’s using after I hang up my headphones, and the difference between a real producer and someone who just edits audio files is night and day. If you’ve ever heard one of the larger interview podcasts, you’ve heard Jason’s work. If the conversation sounded flawless, then you know he’s left his mark.
Jordan Harbinger
Jason has been an integral part of my show’s success and knows both the tech and business inside out.
Tim Ferriss
Jason is my podcasting guru. No matter what question comes up he always has the easiest, most efficient and most effective solution at his finger tips. I trust him completely with the technical stuff, so I can focus on creating the best content.
