Hosted by Justin Johnson. Season one is a spoken companion to the book Builder Leader: The AI Exoskeleton That Crosses the Gap, one episode per chapter. From there, conversations with builder-leaders doing the real work, and the occasional episode voiced as an AI persona of a builder-leader worth thinking like. <br/><br/><a href="https://rundatarun.io/s/builder-leader?utm_medium=podcast">rundatarun.io</a>]]></description><link>https://rundatarun.io/s/builder-leader</link><generator>Substack</generator><lastBuildDate>Mon, 29 Jun 2026 11:12:17 GMT</lastBuildDate><atom:link href="https://api.substack.com/feed/podcast/2790198/s/411813.rss" rel="self" type="application/rss+xml"/><author><![CDATA[Justin Johnson]]></author><copyright><![CDATA[Justin Johnson]]></copyright><language><![CDATA[en]]></language><webMaster><![CDATA[rundatarun@substack.com]]></webMaster><itunes:new-feed-url>https://api.substack.com/feed/podcast/2790198/s/411813.rss</itunes:new-feed-url><itunes:author>Justin Johnson</itunes:author><itunes:subtitle>The Builder Leader podcast.
