Where fate and finance fuse

INVERTR is not a bank. It’s never just about the money. We’re in it for the long haul. We believe in companies that can reverse common practice for the greater good. Companies that use new technology to turn things around. That put old fashioned thinking upside down. That reverse directions towards more sustainable solutions. Companies that can change matter and make change matter. Like using sustainable heat to desalinate water. Like better filtering of dirty water. Or producing installations to do all of the above. We turn finance into finesse.

Investment portfolio

We do not invest in an infinite number of companies. We select and keep focus. We serve a purpose.

Convert saline water into clean water.

Sustainable Thermal Desalination: Aquastill is the global technology leader in the field of membrane distillation, the natural process to convert saline water into clean water. Our technology can produce clean water on a small to medium scale, at competitive costs and with minimal impact on the environment, using waste heat or solar power to energize the process.

INVERTR - TorrCoal

Convert waste into bio-carbon.

TorrCoal (www.torrcoal.com) is from 1-1-2023 a Perpetual Next Company. After having invested 15 years into the development of torrefaction technology to convert waste streams into bio-carbon, we decided to integrate TorrCoal into a new parent. We consider this as the perfect match to scale up carbonisation as a short-term solution to reduce CO2-emissions.

Rethink on return

We dedicate our ‘wealth’ to science and technology that bring change to the world. We use our money to accommodate the gifted people at our companies. To help them be the best they can be. As far as we are concerned, they are our true capital. Our future founders. So, we hope you found us, because you would like to do business with them. Because you believe in their change to the world as much as we do. We have turned finance into faith.
