Our Story

In 2014, cousins Alen and Long Nguyen had the vision and foresight to solve for a massive gap rising in the commercial cannabis industry supply chain. Alen had in-depth experience within infrastructure and supply chain and Long had extensive, hands-on experience in the cannabis market.

They launched MainStem in Seattle with a plan to solve supply chain for the industry, and in the beginning, it was two guys, a truck and a warehouse. The high-touch, personalized service we offer today was born from those early days when Alen and Long personally delivered orders to customers. As their distribution business grew, they began building a larger-scale solution to address the Washington cannabis supply chain issues.

At the time, Washington was one of the two pioneering states in the legalized commercial industry, but as the regulated market expanded, so did MainStem. The company and technology has evolved significantly over the years as customers' needs have changed from State to Regional, then from National to Global.

As a result, MainStem has adapted their solutions to meet both current market gaps and future needs, and is now the leading B2B Supply Chain Ecosystem built for the cannabis Industry. Today, MainStem serves the entire legal cannabis market in the US, and has shipped over 140,000 supplies to 45 states, as well as Canada, Jamaica, and Puerto Rico.

The MainStem mission has always remained the same – to solve the supply chain issue for the cannabis industry. Today, the MainStem platform provides access to over 10,000 products from over 400+ brands.
