Most recently, Harner was the Chief Marketing Officer for AURA Technologies, a leading health, safety, and security technology provider. 

“Addressing the global clean water crisis has been a passion of mine for as long as I can remember,” said Harner. “I’m thrilled to join ZwitterCo at this pivotal time in history to begin telling the stories of our customers championing sustainable water treatment and reuse.

This announcement follows a year of notable achievements for ZwitterCo, including the expansion of its leadership team, welcoming Chris Ling as the new Chief Financial Officer and Jennifer Rehder as Vice President of Operations. The company was named to Fast Company’s prestigious list of the World’s Most Innovative Companies of 2024 and received the Breakthrough Technology Company of the Year Award at the Global Water Summit in 2023.

Recently, ZwitterCo debuted its newest product, a zwitterionic reverse osmosis (RO) membrane, which is the first brackish water RO membrane built using fouling-immune technology that lasts two times longer and reduces cleaning up to 90%. The new RO membrane comes on the heels of ZwitterCo opening its 30,000-square-foot innovation center, accelerating the development of its products and providing a research and prototyping space for innovation.
