Harn Soper (CEO and founder of SFP) is past president and current board member of Soper Farms Inc. Soper Farms is a 900-acre family century farm in northwest Iowa. Under his guidance Soper Farms has transitioned their farms from conventional GM-based chemical farming to organic specializing in row crops. This perspective gives Harn a unique side-by-side understanding of multiple farming systems, their advantages and disadvantages.

Seeking further farm efficiencies, Harn was instrumental in conducting on-farm energy research including grants from the University of Northern Iowa Farm Energy Working Group. Teaming with Rich Schuler, MS Physics, and lecturer at the Iowa State University, they developed a prototype small-scale energy extracting system from an integrated aerobic and anaerobic compost system.

Harn graduated from Colorado College with a Bachelor of Arts degree in music. As an entrepreneur in Silicon Valley, his career covered music production and composing working with world-renowned musicians such as George Winston and Will Ackerman. As an early adopter in digital recording he expanded his focus towards digital audio/video technology and Internet asset security with Pinnacle Systems, Avid Technology, Harris Broadcast and numerous broadcasters worldwide including US broadcast and cable companies NBC, ABC, CNN and international media companies including TVB Hong Kong, the Australia Broadcast Corporation and the BBC and ITN in the United Kingdom.

Upon leaving the technology field Harn returned to the fields of Iowa focusing on his family farms and starting Sustainable Farm Partners. He now serves on the board of the Organic Farming Research Foundation (OFRF) and, through Green America, works with industry groups developing solutions to increase the availability of non-GMO and organic grains across the supply chain.
