Our Track Record: We Built and Operated in Massachusetts Cannabis
We've operated what we now help save.
Grey Birch Associates is led by operators, not liquidators. Before founding GBA, co-founder Carl Giannone built and ran Trade Roots, Massachusetts' first vertically integrated social equity cannabis company (Wareham, 2017 to 2025): cultivation, manufacturing, and retail under one roof, a $4.9 million Series A raised almost entirely from local investors, and a seven-figure operation with a team across every license type.
He also saw the downturn coming. Trade Roots passed on a permit to double its grow, and Carl publicly warned about the wholesale price collapse months before it arrived. The trade press nicknamed him "Calamity Carl," and Leafly later documented the very crash he predicted. When Trade Roots wound down, the GBA team lived the exact distress it now manages for lenders, creditors, and courts. The coverage below is the public record.
