Puraffinity (formerly know as CustoMem) has raised GBP 2.5 million from investiere, Kindred Capital, Heritage Group Ventures and prominent business angels including Charlie Songhurst (Microsoft Head of Corporate Strategy) and Matt Clifford (CEO Entrepreneur First). investiere contributed GBP 0.3 million to this round. 

Puraffinity has developed a novel bio-based adsorbent material that can selectively capture micro-pollutants including pesticides, pharmaceuticals and high-performance chemicals like Per- and polyfluoroalkyl substances (PFAS) from wastewater. Puraffinity’s solution enables customers to adhere to increasingly stringent wastewater regulations and help to protect their local ecosystem.

The company is rebranding and changing its name from “CustoMem” to “Puraffinity” to reflect the broad application of its technology to design an array of materials for purification by leveraging the power of chemical affinity principles.

“By successfully raising seed capital finance, we can accelerate our scale-up and deploy our technology in global markets that are in immediate need of a solution to the PFAS problem,” said Puraffinity Chief Executive Officer Henrik Hagemann.

“CustoMem’s team combines top talent across a myriad of disciplines and world-class expertise both in technical and commercial scale-up of cutting edge solutions in the water space”, said Romeo Bütler, investiere’s investment manager responsible for the case.
