ZwitterCo Raises $5.9M in Seed Financing


ZwitterCo, a Boston, MA-based fouling-resistant membrane technologies provider, closed its 5.9m seed financing.

The round was led by global filtration and separations technologies leader Mann+Hummel Corporate Ventures in collaboration with R-Cubed Capital Partners, and with additional support from Burnt Island Ventures and individual investors.

The company intends to use the funds to scale its water treatment and advanced separations solutions, completing final field testing in several key markets, expanding commercial production, and continuing to support its list of customers and channel partners.

Led by Alex Rappaport, CEO, ZwitterCo provides hydrophilic membranes that can filter historically un-filterable process water and wastewater that is rich with fats, oils, proteins and other hard-to-remove organic compounds. The company is targeting applications in bioprocessing, agricultural waste treatment, food and beverage, and other industries where standard membrane solutions foul and quickly degrade in performance.

Founded in 2018 after being spun out of Tufts University, ZwitterCo has received recognition and funding from the U.S. Department of Energy, the Massachusetts Clean Energy Center, the National Science Foundation and others. The company is also an alumnus of the Imagine H2O accelerator program and the Greentown Labs incubator.
