Membrion Raises $2.23 Million in Oversubscribed Series Seed Funding Round to Commercialize Breakthrough Membrane Technology

•Funding includes $1.485 million in seed capital from Clean Tech Angel Investors and $748,000 grant from National Science Foundation
•New investors include Sierra Angels and Sand Hill Angels
•Targets water purification, energy storage and biotherapeutics industries

SEATTLE, December 5, 2018-- Membrion, a manufacturer of ultra-low cost, high performance ion exchange membranes, today announced it has closed its Series Seed round, having raised a total of $1.485 million. Sierra Angels and Sand Hill Angels joined existing investors E8 and the E8 Fund, Bellingham Angel Investors, as well as other prominent angels. This round, combined with a $748,000 grant the company received earlier this year from the National Science Foundation, puts the company on the path to commercialization in 2019.

Membrion will use this funding to continue to scale its novel technology and develop commercially viable membranes for the ion exchange markets in water separation technologies and energy storage applications.

The high cost of current ion exchange membranes and the inferior performance of polymer membranes have held back many of the most promising solutions to today’s clean energy, fresh water and human health challenges. Membrion’s low-cost, high-performance ceramic ion exchange membranes solve both problems, thereby allowing its customers to unlock the true potential of grid-scale energy storage; cutting-edge water purification and desalinization technologies; and advanced filtration in pharmaceuticals and chemical separations.

Membrion leverages silica gel – an inexpensive, non-toxic material that is often packaged with new shoes, beef jerky and many other consumer products – to produce a novel class of commercial ceramic membranes. Membrion’s technology converts the highly absorbent, small-pore silica gel into flexible ceramic membranes that can be engineered to meet the needs of a wide range of applications. It does so at a dramatic cost reduction relative to the current industry leading membranes.

“Our oversubscribed round is a testament to the belief by our investors that Membrion has the right team, the right technology and the right strategy,” said John Plaza, CEO of Membrion. “It’s full steam ahead for us now as we commercialize this breakthrough technology.”

Membrion was founded in 2016 by Dr. Greg Newbloom, based on the technology he developed alongside Professor Lilo Pozzo at the University of Washington’s College of Engineering. Spun out of University of Washington, Membrion has received generous support from UW’s CoMotion, Buerk Center & Clean Energy Institute, the National Science Foundation, Amazon’s Catalyst program, the Murdock Charitable Trust, and the CalTech Rocket Fund.

Membrion’s affordable, high-performance membranes will help unleash a new wave of innovation and market penetration for these technologies. More information is available at
