In 1987, Joel was hired by geologist Ed Fogg, who was starting up a small company called Canadian Discovery Digest Ltd.  Together they created and developed a variety of information products for geologists including Canadian Discovery Digest (87), the Horizontal Drilling Report (91), Current Exploration Overview (CEO) maps (95), Canadian Frontiers CEO maps (98), the United Kingdom Discovery Digest (98), the Strategy 2000 report (99) and its related EDGE software (99), the Norway Discovery Digest (01), and many other geo-innovations.  Joel was an integral part of Canadian Discovery Ltd.

In 2006, Joel began working with Mike Sherwin of Sherwin Geological Consulting Ltd.  After a year of successful growth and expansion they became business partners and temporarily renamed the company Sherwin GeoEdges Inc. (which was shortened to GeoEdges Inc. two years later). 

Over the past 30 years, Joel has been involved in the creation and development of a variety of geological exploration tools and he has marketed those extensively to a wide network of contacts in Canada, the USA, Western Europe, and Australia.
