OZO Coffee Roasters

OZO Coffee Roasters is a Boulder, Colorado-based specialty coffee company founded in 2007 by Justin Hartman. Over nearly two decades, the company has maintained its status as an independently owned and operated business, expanding to five café locations across Boulder and Longmont without the use of venture capital or national scaling models. The company began roasting its own coffee in-house in 2009 and currently operates a dedicated roasting facility using Diedrich and Gothot equipment to maintain small-batch production standards.

The company’s operational philosophy centers on the integration of coffee production with community infrastructure. OZO functions as both a retail operator and a wholesale partner, providing coffee, equipment, and training to various local businesses, including hotels, restaurants, and markets. By keeping production in-house—ranging from roasting to the creation of house-made nut milks—the company emphasizes a hands-on approach to quality control that contrasts with the outsourcing trends common in larger coffee chains.

Sourcing at OZO is defined by a commitment to ethical and sustainable practices, with the company maintaining direct relationships with producers across Africa, Latin America, and Asia. As a member of World Coffee Research, OZO participates in broader industry efforts to support the long-term viability of coffee farming. A documented example of this approach is their partnership with the Abateraninkunga ba Sholi Cooperative in Rwanda, where the company has supported women-led initiatives, including a beekeeping project designed to diversify farmer income and increase agricultural resilience.

Sustainability is a core pillar of the company’s internal metrics. OZO tracks its environmental impact through quantifiable programs, such as their 'Own Cup' initiative, which has diverted tens of thousands of disposable cups from landfills. Other efforts include the use of reusable containers for wholesale deliveries and a canister refill program for retail customers, reflecting a strategy that prioritizes measurable waste reduction over symbolic gestures.

Beyond its supply chain and environmental efforts, OZO is deeply embedded in the Boulder-area community. The company regularly contributes to local organizations and schools, viewing its cafés as essential gathering spaces. This grassroots growth model has earned the company consistent local recognition, including 'Best of Boulder' awards and the Virginia Patterson Business of the Year award from the Downtown Boulder Partnership.

Today, OZO stands as a representative of the 'independent specialty' model, where growth is driven by community loyalty and word-of-mouth rather than aggressive expansion. By balancing its role as a wholesale supplier and equipment service provider with its identity as a neighborhood café operator, the company maintains a focus on craft and service that has allowed it to remain a fixture in the Colorado coffee scene for nearly twenty years.
