Koolboks Named on the 2023 Cleantech 50

Koolboks has been named on Cleantech Group’s 2023 Cleantech 50 to Watch.  The Cleantech 50 to Watch is an annual list of top global early-stage private companies showcased for their excellence in sustainable innovation.



 The Cleantech 50 to Watch companies were recognized at the upcoming Cleantech Forum Europe on November 14-16 in Tallinn. 

The entrepreneurs on the list are creating new technologies that are poised to address the climate crisis from soil monitoring to solar to water scarcity and everything in between.  

To create the list, inputs are combined from the Cleantech 50 to Watch expert panel of 32 leading investors, corporate and industrial executives who are active in technology and innovation scouting.    The panel nominated the companies that most impressed them with their early-stage high-impact solutions.  These were combined with Cleantech Group research on public early-stage awards which then put the companies through qualitative and impact filters.  A shortlist of 150 companies was reviewed and scored by the expert panel to reach the final 50.   The Cleantech 50 to Watch companies are located in 21 countries.  These innovators are delivering sustainable solutions in these five industry groups:  

  • Agriculture & Food  

  • Energy & Power

  • Materials & Chemicals

  • Resources & Environment

  • Transportation & Logistics

“The companies in this year’s Cleantech 50 to Watch are younger, faster, and gutsier,” said Richard Youngman, CEO, Cleantech Group. “This year’s list is a testament to the dynamics that we are seeing slowly crescendo in the overall cleantech innovation universe, and indeed the same ones that will be necessary to tackle the most pressing climate challenges.”
