Allan Chegus


Allan is on a mission to transform the oil and gas industry. He believes we can get much more from existing capital investments by using technology that allows for smarter, more informed decisions.

As one of the founding partners of Stream Systems, Allan is a strategic business thinker with a bold vision, insatiable curiosity and a desire to make a difference. An Engineer by study, he has developed a knack for solving complex business problems by implementing innovative technology solutions to enable a more informed decision-making process. Allan started his career in operations with the American multinational consumer goods company Procter & Gamble where he quickly learned the intricacies of working for a large, vertically-integrated company. In 1989, he joined Dow Chemical as a Senior Project Engineer and was responsible for managing operational improvement and capital expansion projects.

Six years later, Allan was given the opportunity to transform his career and join the commercial side of Dow Chemical as Director, Procurement and Supply Chain and become part of the newly centralized global leadership team. During this time, he successfully developed new business processes, contracts/vendor agreements and transitioned over 50% of the group’s Canadian workforce resulting in a 10% savings for the company nation-wide. Allan left Dow Chemical in 2000 following a consolidation of its North American Operations, having just completed his Master of Business Administration from the University of Alberta.

Seeing the transition as an opportunity to gain valuable experience in other sectors, Allan spent the next four years working in senior leadership roles for reputable organizations AT&T and KPMG (BearingPoint). Allan started his own consulting company in 2005 servicing a variety of energy, utility and banking organizations including Enbridge, EPCOR, Enmax and ATB Financial. The company evolved and began specializing in large information technology projects where Allan was able to apply his expertise in operations and design engineering as well as automation. After leading the development of multiple pipeline simulation projects, Allan saw the opportunity to establish Stream Systems in 2014 and develop a new software platform that was superior to those he had been exposed to previously.

Today, Allan is driven by the desire to continue to create employment opportunities in Alberta as well as to assist industry leaders in better understanding their operations. Each element of his multifaceted background is equally important in contributing to the innovative leader he is today who is determined to transform the oil and gas industry and beyond.

Allan has an engineering degree from the University of Manitoba and an MBA from the University of Alberta. He is a registered professional engineer.
