AI for demo creation: Demo Data Agent

The State of Presales and Demo Technologies, and What's Coming in 2026

In this episode, Jack Cochran and Matthew James are joined by Justin McDonald, Co-founder and CEO of Saleo, to discuss how demo automation technology is transforming the presales landscape. They explore the evolution of presales over the past 20 years, the hidden costs of demo preparation (the "demo tax"), and how AI is revolutionizing how solutions engineers create and personalize demonstrations. Justin shares insights on building relational capital, the importance of in-person meetings, and why the future of presales lies in leveraging technology to spend more quality time with buyers.
