Single Source is a Colorado-based company that specializes in creating premium, solventless cannabis concentrates and flowers. The company operates on a "seed-to-final extract" philosophy, meaning they control every stage of production, including genetic selection, cultivation, and processing. This vertical integration model allows them to maintain complete quality control and consistency.

The founders, Tony Karas, Logan Nuss, and Kennn Wall, are known for producing high-quality live rosin and full-melt hash. While the exact founding year of the "Single Source" brand is not explicitly stated, it's known that the founders started as a rosin lab and began selling recreational flower in or before 2022.
