From Oil Prices to Storage Units: Building a Business You Control with Karl Graham of Luminus Capital

Karl Graham, Co-Founder of Luminus Capital, joins Matt Engfer to share his journey from oil and gas exploration to building a growing self-storage platform across the heartland.

After spending a decade making high-stakes investment decisions in a volatile and capital-intensive industry, Karl realized he wanted something different. He wanted to build a business where execution, discipline, and team performance had a greater impact than external forces. That shift ultimately led him into self storage.

In this episode, Karl walks through how Luminus Capital scaled from individual syndications to launching a fund, why geographic focus creates a real operational edge, and how disciplined underwriting and risk management have shaped their growth. He also shares how his team is leveraging data, marketing, and AI. This includes analyzing tens of thousands of customer calls to improve sales performance and building more advanced revenue management systems to stay competitive in today’s market.

This conversation is a practical look at what it takes to build and operate a successful storage business today and why the days of easy storage are behind us.
