Glass House Brands

Glass House Brands

Kyle Kazan and Graham Farrar launched Glass House Brands in 2015, starting with a single greenhouse farm in Carpinteria, California. The firm is structured as a vertically integrated cannabis company, not a traditional family office, with operations spanning cultivation, manufacturing, brand building, and retail. Glass House owns 6 million square feet of state-of-the-art greenhouse space and ranks among the top five flower brands in California by market share. Its portfolio includes consumer brands such as Glass House Farms, PLUS (California's #4 edibles brand, acquired in 2022), Allswell, Forbidden Flowers, FIELD, and Mama Sue Wellness. The company operates ten retail dispensaries under the Farmacy brand in cities including Santa Ana, Santa Barbara, Berkeley, Santa Ynez, and Isla Vista. Its cultivation cost sits below $135 per pound, giving it a structural cost advantage. The company's geographic focus is entirely California, with no confirmed operations outside the state. As of 2025, the company reported approximately 700 employees per its public filings. In July 2024, Glass House became the first plant-touching cannabis stock available on Robinhood. In October 2024, the company announced an accelerated 2026 expansion strategy, and in May 2025, it appointed Alison Payne to its board of directors (per the firm). Glass House's structural differentiator is its pure-play California vertical integration, combined with a low-cost greenhouse cultivation model. It does not operate as a family office but as a publicly traded cannabis operator on Cboe Canada (ticker GLAS.A.U) and OTCQX (GLAS.F), giving it a governance structure distinct from private family offices in the sector.
