Michael Hennessy is the Founder of Lineage Merchant Partners, a leading independent investment bank serving operators and investors in the cannabis industry. Since launching the firm in 2021, Michael has established Lineage as one of the sector's leading independent advisors, with a strong track record across M&A, capital markets, and strategic advisory — and a continued presence at the forefront of dealmaking in cannabis.

Michael brings over 15 years of investment banking experience to the firm, including roughly eight years dedicated specifically to cannabis — making him one of the more tenured dealmakers in the space. Prior to founding Lineage, he held senior roles at investment banks focused on emerging industries, and began his career at Citigroup, where he built the technical foundation that continues to inform Lineage's institutional approach to client service.

Today, the Lineage team serves as a trusted advisor to leading cannabis operators across the United States, with a focus on disciplined execution and long-term client relationships.
