Green Check

Green Check builds compliance and risk-monitoring software that financial institutions use to bank cannabis-related businesses — automating account onboarding, ongoing transaction monitoring, and the state/FinCEN reporting that BSA/AML cannabis banking programs require. Its platform gives banks and credit unions a system of record for cannabis relationships plus advisory services for building and running a compliant program, and it has grown to also serve MSBs, fintechs, and gaming/specialty-finance customers as of an August 2026 platform expansion beyond cannabis.

Founded in 2017 by CEO Kevin Hart and headquartered in North Haven, Connecticut, Green Check is venture-backed (investors include Mendon Venture Partners and Silverleaf Venture Partners) and has grown through acquisitions including Komplyd and PayQwick. It works directly with community banks and credit unions across the U.S. that maintain active cannabis banking programs.
