ZwitterCo, which recently commissioned its Innovation Center at its headquarters near Boston, will use the funds from its Series B to strategically invest in international expansion and the rapid advancement of its technology platform, further solidifying its position as a leader in the water treatment industry.
“Climate change is simultaneously driving water scarcity and increasing demand for water in industries critical to the low-carbon transition,” said ZwitterCo Co-Founder and CEO Alex Rappaport. “This funding will allow us to rapidly scale our breakthrough membrane technology, empowering industries to reliably and affordably access unconventional water resources while ensuring the water used or recycled in these industries meets the highest purity standards.”
While membranes are ubiquitous in water treatment, there had been no breakthrough innovations in the field for half a century until ZwitterCo introduced membranes with novel zwitterionic chemistries. ZwitterCo’s technology creates unprecedented immunity to organic fouling, enabling ZwitterCo’s membranes to continue working efficiently and sustainably long after traditional membranes would have clogged.
Jason Pontin, General Partner at DCVC and Chairman of ZwitterCo’s Board of Directors, said, “Long before the planet feels the worst of climate change, without new solutions and more efficient water markets, cities and farms around the globe will suffer severe water stress,” Pontin said. “Reusing unconventional water sources is the only way to achieve water resiliency, and ZwitterCo’s groundbreaking membrane technology is the key deep tech breakthrough that makes water reuse practical and economical. DCVC has invested in ZwitterCo at every stage from its last Seed round, because nothing is more important than the company’s work to secure a sustainable water future.”
