Retail partner across Bangkok.
Stash BKK Co., Ltd. is a separately owned Thai company that operates four cannabis retail storefronts across Bangkok. It is Greenstead's commercial retail partner — not a subsidiary. The relationship is operational: Stash distributes Super Leaf at every storefront, and uses Flippie for in-store print fulfillment.
Why a portfolio
Each Greenstead brand serves a different customer with a different product. They share infrastructure, not branding — supply chain learnings from Super Leaf inform Flippie's fulfillment, Sarapab's digital reach informs how the portfolio understands modern Thai consumers, and the retail surface that Stash BKK provides is real, weekly distribution for our physical goods.
The thesis is patient: good brands grow better when they grow alongside other good brands.
