As an engineering student at JBU in 2013, Gunnar Shafer worked on a team research project for a solar battery-powered, off-grid farming system. Shaffer developed the vertical farming towers used in the project, eventually creating YouTube videos of the making of the towers that have garnered more than one million views. After earning an M.Sc. in renewable energy from Universität Oldenburg, Germany, and completing his master’s thesis at the United Nations in Geneva, Switzerland, Gunnar kept thinking about the commercial possibilities for the towers.
In 2017, he launched Agrowponics, a vertical-farming manufacturing company, with Thomas Burns. A seventh-generation farmer, Shaffer combines his solid agricultural and engineering backgrounds to serve as the CEO. He also works full-time at Southwest Power Pool as a market forensics engineer.
