6Storage was founded in 2007 by Michelle Otto, an experienced self-storage owner/operator. The business originated from her family's direct experience managing storage facilities and the challenge of finding affordable, flexible management software. Michelle, her husband Jim, and later their daughter Jessika (now VP of Operations) built 6Storage from the ground up to address real-world needs in the industry, expanding from handling hundreds of units in Iceland to supporting facilities across the U.S. and around the world. The leadership has remained family-centered, with deep roots in operations and facility management, and the company has demonstrated steady, organic growth
