UniSieve builds high-precision molecular-sieving membrane systems that help industrial companies separate gases with less energy and lower emissions.
Industrial separation and purification account for an estimated 10–15% of global energy use, while UniSieve says its membranes avoid conventional heating and cooling and can reduce separation energy by up to 90%. The $9 million Series A brings total funding to USD 25 million to scale pre-commercial olefin and point-source carbon-capture systems backed by field-validated performance and paying customers.
