Co-founder and CEOMainStem

Seattle Area

Member Since January 2022


Alen Nguyen co-founded MainStem with his cousin in 2014 to solve supply chain and product distribution for ancillary products in the cannabis industry. As its Chief Executive Officer, Alen has seen MainStem become the leading B2B e-commerce marketplace and integrated supply purchasing platform for cannabis companies across the U.S. over the past seven years. After obtaining his Electrical Engineering degree from the University of Washington and working within the aerospace industry near Seattle, Alen quickly realized his true passion lay on the business end of the spectrum and procured an MBA in Entrepreneurial Studies from Embry-Riddle Aeronautical University in 2013. Surprisingly, it was his time in aerospace that helped Alen identify the massive gap between the commercial cannabis supply chain and product distribution that ultimately paved the way for the creation of MainStem as a better way to connect cannabis businesses directly with suppliers. The need to build cannabis infrastructure from ground zero provided an opportunity to explore how highly regulated but still fragmented systems could fit together on a macro level. This pursuit eventually made MainStem the industry’s leading purchasing platform, providing access to more than 12,000 products from over 485 brands to thousands of customers across the United States. When he’s not developing solutions to some of the cannabis industry’s biggest issues Alen can be found spending time with his wife and three children.
