What does a founder learn after selling four companies, burning one to the ground, and spending years building AI agents before “AI agents” became the phrase of the moment? Dennis Mortensen has the scars to answer that. A Danish-born, New York-based serial founder, Dennis has built and exited companies across analytics, media optimization, and AI, including X.ai, the AI scheduling assistant that raised $44 million from FirstMark and others before being acquired by Bizzabo in 2021. Today, he is building LaunchBrightly, a company automating product screenshots for help centers - a problem that sounds painfully unsexy until you realize every software company has it, every product team pays for it, and every outdated screenshot quietly creates support debt. In this episode, Dennis joins Brian Bell for a wide-ranging masterclass on founder judgment, painful pivots, and the unglamorous infrastructure problems that make or break software companies.
