Report this content

Loudspring portfolio company Sofi Filtration Oy has signed a 3M€ investment round. The proceeds will be used to accelerate the growth of Sofi Filtration Oy.  At the same time Loudspring will purchase shares in Sofi Filtration Oy from early investors. More information will be made available in a few weeks once the financing round is closed. Sofi Filtration provides efficient water filtration technology. Their self-cleaning filter, the innovative Sofi Filter® enables cost efficient micro filtration of large amounts of water. The company focuses on marine, oil&gas, mining and power generation industries, with end-customers mainly in North America and Northern Europe.  The company has also conducted successful pilots in new industries, such as the plastics industry, which it considers to have high potential due to the increased awareness of microplastics contamination.


CEO, Loudspring Oyj Jarkko Joki-Tokola:

“Sofi was on a rapid growth trajectory when the pandemic caused a significant negative impact on Sofi as the market for investment goods halted and customer deliveries stalled. We have always been aware of the high quality of Sofi Filtrations technology and the new lead investor provides Sofi with industry expertise and the resources needed to build a world-leading water technology company.” 


CEO Sofi Filtration Ville Hakala:

”For a number of years now Sofi Filtration has developed its processes to effectively enter new markets and has established brand awareness as the go-to technology when it comes to automatically self-cleaning microfiltration. However, as we learn how our technology’s capabilities match increasing global water treatment needs, we have painfully acknowledged our limited financial resources to serve our large client industries. To tackle this problem, we set ourselves out to find the best investor in our specific field of business. After this financing round closes we will have the resources to grow our business to the technology’s full potential.“
