Darryl Weisz

Executive Director

“I am ‘sold’ on the fact that cannabis is a wonder plant. In 2016, I was diagnosed with skin cancer and underwent a 12-month treatment. To counter the numerous ill effects of my treatment, one of my doctors recommended cannabis medication. I was astounded at how it alleviated my symptoms and helped me cope with the side effects.”

Following his university studies, Darryl started his career at Nampak Ltd, initially in HR management as well as in various sales and marketing roles across various industries.

In a 30-year corporate career spanning numerous industries, Darryl has built a broad range of business experience in local and international markets by managing businesses and major FMCG and industrial brands across the world. These include managing the brand portfolios of the Kellogg Company of South Africa and Nampak Tissue (now Twinsaver Tissue). 

After being appointed as Managing Director of Nampak Tissue (2003), Darryl was the Managing Director of the Strategic Ventures division of the Liberty Group (2009) and the Managing Director/Sales & Marketing Executive in the Hulamin group (2012). 

Darryl currently occupies numerous non-executive positions in various small-to-medium companies. He consults in strategic planning and business growth on both a professional and pro-bono basis. His ongoing community work includes the Chairmanship of the ORT Bursary Trust, an international educational and skills enhancement non-profit organisation where he is a board trustee.

Paul Bacher

Executive Director

I have seen the benefits of this wonder-plant first hand when a member of his family used CBD oil to great success to cure a chronic and painful condition. I am drawn to sunrise industries with enormous growth potential – and cannabis is a natural fit.”
