William "Billy" Dietz spent about 20 years in the tea industry, including as an R&D lead at DAVIDsTEA, before co-founding BDH Consultants alongside Don Ho, who built and exited an eight-figure tea and foodservice business. Together they created the Founder's Circle to help North American tea entrepreneurs avoid costly early mistakes.

Through the Circle, Billy and Don give members direct supplier introductions, proprietary business templates, and expert guidance across DTC, cafe, retail, and wholesale tea business models.
