Climate Comes First

We are all about climate first. We invest in deep decarbonisation technologies that will lead us to a world beyond fossil fuels. Extantia literally aims at the aspect of survival; not only of our planet, but also of humanity, of our values, of our culture of inclusion and progress. There is no  better way to achieve this than by supporting the next generation of mission-driven founders.

Here is why climate tech is the most crucial industry right now:


tonnes of CO2e emissions need to be reduced each year to reach net-zero by 2050.


of the technologies required to reach net zero by 2050 are still under development and urgently need funding to be market-ready.


is how much venture capital funding of climate tech increased from 2018/19 to 2020/21, which is more than $40 billion.
