Who we are

Our mission

The Tech for Net Zero Alliance is a network of leading climate tech startups, scaleups and investors in Germany and the DACH region. To accelerate the scale-up of breakthrough climate technologies, the alliance focusses on expanding climate tech finance, stimulating market demand, and adopting an enabling regulatory environment.

Given the abundance of technical solutions, talent, and financial resources, we believe achieving the climate targets is a matter of speed, focus, and execution. We need all hands on deck to move faster and turn Europe into a climate tech powerhouse.

As a Climate Tech Think Tank, the Tech for Net Zero Alliance is a reliable partner for policy makers, investors, and founders. In addition, the Tech for Net Zero Alliance supports the Climate Tech ecosystem in Germany, Europe and beyond.


The alliance is a network of founders of climate tech startups as well as venture capital investors with a clear climate focus. The alliance is additionally supported by a network of think tanks, research, science, and the established economy.
