The story of the WeGrow Group – from the windowsill in Bonn to the whole world

More than 13 years ago, the two founders of WeGrow discovered the Kiri tree in the botanical garden of the University of Bonn, Germany. They founded the company in their student appartement. Today, the company supplies customers in 39 countries worldwide.

WeGrow AG – driven by passion and innovative spirit

The company WeGrow was founded in 2009 by agranomist Peter Diessenbacher and economist Allin Gasparian. During their student days at the University of Bonn, Germany, the two founders discovered the extremely fast-growing Kiri tree in the university’s botanical garden. With their first own Kiri tree variety, NordMax21®, the two succeeded for the first time in successfully cultivating the Kiri tree for sustainable timber production in Germany as well. What began under the pitched roof of Diessenbacher’s student flat has since developed into the market-leading company in the field of sustainable Kiri wood production in Europe. However, with customers in 39 countries on 5 continents by now, WeGrow has also been able to position itself successfully beyond the borders of Europe.
