The way Scott Boston sees it, a career is like an investment strategy. "There’s always a tradeoff between risk and reward. If you take a chance and challenge yourself, you can accelerate your growth," he says. Perhaps it’s not surprising then that the Calgary-based accountant landed the position of corporate controller at Tesla Exploration Ltd., one of the world’s largest international seismic contractors, in 2013 at the age of 27. After nearly three years with Deloitte working in the energy sector, Boston moved into industry with Niko Resources and joined Tesla a year later. With operations throughout Canada, the US and the UK — and a 2014 revenue of $170 million — the company is set to take on contracts in eastern Africa this year and hopes to expand to South America.
