Moleaer, a nanobubble technology company, closed a $9 million Series B fundraise led by S2G Ventures’ Oceans and Seafood Fund and joined by existing investors, ADM Capital’s Cibus Enterprise Fund and Energy Innovation Capital.

Moleaer will use the latest funding to expand the company’s global commercial and manufacturing operations, advance its research and development of new nanobubble applications, and introduce new service offerings, including equipment and water quality monitoring and nanobubbles-as-a-service (NaaS). 

The company’s nanobubble oxygen injection technology was tested in salmon farming with a 22% increase in biomass production, a 60% reduction in oxygen usage and a 42% reduction in electricity consumption. In the past year, Moleaer has grown rapidly, tripling in size, and expects to continue to see that growth going forward. The company has over 1,000 installations and is treating more than 225 million gallons of water per day in agriculture, aquaculture, surface water and natural resources.

“Moleaer’s nanobubble technology has incredible potential to make agriculture and aquaculture more sustainable and productive, restore the health of aquatic systems and provide meaningful worldwide advancements in water quality,” said Larsen Mettler, S2G Ventures managing director.

“This financing round - the largest of its kind for a nanobubble technology company - demonstrates the importance of innovative technologies that improve the sustainability of food production and water treatment. With issues of food insecurity and the growing deterioration of global water quality, industries are looking for chemical-free solutions to meet the challenges associated with climate change and resource scarcity. This funding will allow us to accelerate our global expansion to meet these needs, whether that’s in food, water, energy, or other applications,” said Nicholas Dyner, CEO of Moleaer.
