Membrion, a spin-out from the laboratories of the University of Washington (UW), is a manufacturer of lower cost, high performance ion exchange membranes.

Membrion makes membranes that filters molecules under any conditions.

Membrion was founded in 2016 by Greg Newbloom. The company is headquartered Seattle, Washington.


Membrion has developed breakthrough Molecular Self Assembly (MSA) technology that uses readily available, non-toxic and low-cost materials to produce advanced ceramic ion exchange membranes which perform better and cost significantly less than today’s ceramic and polymer options.


Membrion is currently deploying this versatile technology to the rapidly growing desalination market, helping to address the global water crisis. 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.


Membrion is backed by Bellingham Angel Investors, WRF Capital, SeaChange Fund and others. The company closed its Series A with a total of $6M on Mar 04, 2020. This brings Membrion's total funding to $11.4M to date.
