John de jonge
advisors
John’s passion for the dairy industry began on a dairy farm in Pitt Meadows, BC, Canada. From an early age, he had hands-on experience with daily management of a 150-cow dairy farm and farming of 500 acres of land. In 1990, he graduated from Olds College in Alberta, Canada with a degree in Agricultural Mechanics, Agricultural Engineering and Business. In 1995, John bought Artex Fabricators based in Langley, BC, Canada, a company that manufactured and distributed manure spreaders, silage equipment, and stabling for dairy barns to customers across North America.
Part of John’s passion is feeding the world and in diversifying away from dairy farming he has recently invested and partnered in the starting of Cubic Farms, a leader in the local chain Ag-tech which crates agricultural technologies to feed a changing world. John was the leading force in the Cubic Farm’s acquisition of Hydrogreen, an on-site automated indoor vertical hydroponic growing system for animal feed. Both companies have grown to become industry leaders in technology and equipment manufacturing.
In 2021 John sold Artex to an investment company and has been focusing on building technological solutions for various industries. John’s passion lies in the creation of technologies that span multiple market sectors to provide unique solutions to the challenges these industries experience.
