Cannabis entrepreneurs, investors and wannabes are descending on Colorado to attend the ArcView Investor Network conference on June 23 where entrepreneurs will pitch high net worth accredited investors in a Shark Tank-like forum. Featured speakers include Surna CEO Tom Bollich, Attorney Tae Darnell and Dutchess Capital co-founder Doug Leighton. The investor group will meet in the Helen Bonfils Building at the Denver Center of Performing Arts. A day later, the National Cannabis Industry Association will launch its first CannaBusiness Summit at the Colorado Convention Center where 800 people are expected to attend. Panel discussions include what you need to know about cannabis penny stocks, innovation cultivation technologies and how to survive in a cash-only world. Leaders describe the summit as the place to be for those in the cannabis field or who want to be.
