Mac, who co-founded MAGENN with inventor and CTO Fred Ferguson, regularly made local headlines in the ’90s for his lavish lifestyle and fortunes as leader of the mercurial computer service company Rebel.com and M4 Technologies Corp., an IT security firm. Pierre, one of the founders of Mississauga-based clean tech company Hydrogenics, spent 20 years with the Canadian Air Force as an aerospace engineer, making him a good fit for MAGENN whose key technology is a lighter-than-air rotor system that generates energy through wind power. Pierre earned an MBA from Western, an ME (mechanical) from U of T and a bachelor of engineering from Royal Military College.
