How to Build Authority Through Podcasting and Storytelling | Harry Duran | 389
Harry Duran, founder of Fullcast and creator of Podisphere, joins Jeff Mains to explore what it really takes to build a sustainable podcast, grow a content brand, and stay ahead in a rapidly AI-shaped media world. Harry shares his journey from corporate marketing at JPMorgan Chase and E-Trade, to launching his first podcast Podcast Junkies in 2014, to building Fullcast — a podcast production and marketing consultancy that has helped over 130 business owners launch and grow shows. He also dives deep into his newest ventures: Podisphere (a G2-style SaaS directory for podcast tools) and Podclaw (an agent-first podcast hosting platform built for AI agents, not humans). The conversation covers the seismic shift happening in content creation right now — from vibe coding and Claude Code to autonomous AI agents that market products while you sleep. Harry and Jeff also discuss why long-form human conversations are becoming more valuable in an era flooded with AI-generated content, the power of niche podcasting, and why the most important skill for the next decade may simply be learning how to talk to robots.
