## About

Based in Massachusetts, US, ZwitterCo, Inc. was founded in 2018 by co-founders Alex Rappaport, Christopher Drover, and Christopher Roy. The company received recognition and funding from the U.S. Department of Energy, the Massachusetts Clean Energy Center, and the National Science Foundation. In addition, ZwitterCo is a graduate of the Imagine H2O accelerator program and the Greentown Labs incubator. The company raised Seed funding in March 2021. In April 2024, ZwitterCo, Inc. raised USD 55 million in series B funding led by new investor Evok Innovations, with participation from other new investors Data Collective, BHP Ventures, Munich Re Ventures, Siteground and Blue Horizon Advisors. 

ZwitterCo technology allows for the reuse and recycling of water resources through its nanofiltration technology, which prevents organic molecules from fouling RO systems and is chlorine-tolerant, back-washable, and has unprecedented resistance to irreversible fouling, allowing for effective water recycling and decreasing membrane fouling in industrial water treatment applications.

The company plans to use the April 2024 funding to expand into the potential of unconventional water sources, such as industrial wastewater.
