Grassroots Cannabis was one of the largest private, vertically-integrated multi-state cannabis operators in the United States. Founded in 2014, the company focused on cultivating, processing, and dispensing high-quality cannabis products across various states. Known for its strong brand presence and rapid growth, Grassroots Cannabis developed a significant footprint in key markets. In July 2020, Grassroots Cannabis was acquired by Curaleaf Holdings, Inc., a leading U.S. cannabis company, in a landmark deal that further solidified Curaleaf's position as a market leader. Post-acquisition, Grassroots' assets and operations have been integrated into Curaleaf's broader portfolio.
Served as the primary corporate office, overseeing strategic direction, finance, legal, marketing, and operational coordination for its multi-state cannabis cultivation, processing, and retail businesses prior to its acquisition.
Located in a commercial building in downtown Chicago's Loop district, the office was likely designed for a modern, collaborative work environment suitable for a fast-paced growth company. Specific unique architectural details are not widely publicized.
Reportedly entrepreneurial and fast-paced, reflecting its rapid expansion in the nascent cannabis industry. The culture emphasized compliance, community engagement, and building a strong brand presence across its operational states.
This HQ directed the growth of Grassroots into one of the largest private U.S. multi-state cannabis operators, playing a key role in shaping its operations, brand, and eventual landmark acquisition by Curaleaf.
Prior to its acquisition by Curaleaf, Grassroots Cannabis operated exclusively within the United States. It had a significant multi-state presence, with operations and licenses in 11 states, including Illinois, Pennsylvania, Maryland, Michigan, Massachusetts, Ohio, Oklahoma, Arkansas, North Dakota, Nevada, and Connecticut. These assets became part of Curaleaf's broader North American footprint post-acquisition.
