Tilray (TLRY) stock has exploded 890% since the company's well-received IPO in late July.

For Tilray's CEO Brendan Kennedy, the successful IPO represents validation for the risk he took eight years ago to shift careers. Kennedy went from working at a venture capital bank in San Francisco to getting involved with a tech company exploring the cannabis industry to leading the charge at Tilray.

"You only see an opportunity like that once in a lifetime [an industry moving to legalization]," Kennedy told TheStreet. "As soon as I saw it, I knew I had to be involved."
