blue activity a CleanTech water treatment company, founded in 2021, has closed a EUR 8.5 million seed funding round. The round was co-led by Wind Capital (Paris) and Venture Stars (Munich), with participation from Angel Invest (Berlin). Proceeds will be used to accelerate product development and scale commercial operations across European industrial markets.
Strong Investor Confidence in Sustainable Water Technology
The fresh capital will enable blue activity to further develop and scale its innovative technology for the chemical-free and sustainable treatment of industrial evaporative cooling systems. In a market environment characterized by increasing cost pressure across the industrial sector, blue activity’s solution delivers significant OPEX reductions – up to 15% in total cost of cooling water treatment – by reducing chemical consumption, minimizing maintenance requirements, and extending system lifetime.
At the same time, the technology provides a future-proof alternative to conventional biocide-based treatment programs. As wastewater discharge limits continue to tighten and regulatory scrutiny increases, traditional chemical approaches are becoming more expensive and compliance-intensive. blue activity’s treatment method significantly reduces reliance on biocides, lowers discharge-related risks, and supports long-term regulatory compliance.
“We are extremely pleased with the trust our investors have placed in us, strongly supporting our vision for a sustainable transformation of industrial cooling water treatment. This funding round is a decisive milestone in bringing our technology to market and making a real contribution to sustainable industry. With this funding, we will grow our team to 15 people, enabling us to better engage and support our customers.” – Lars Havighorst, CEO of blue activity.
“blue activity delivers a solution that combines ecological progress with economic value. This is precisely the combination driving industrial transformation. Such a high problem-solution fit in an Industry Tech company is almost unique and exactly what we as investors were looking for.” - Raphael Budday, Principal Venture Stars.
"blue activity tackles one of the most underloved inefficiencies in industrial infrastructure. We backed the team because they combine deep domain expertise with a genuinely scalable solution — exactly the kind of climate-critical technology Wind was built to support.“ – Thierry Vandewalle, Founding Partner of Wind Capital.
International Investor Consortium Bets on CleanTech Innovation
The internationally positioned investor consortium underscores the growing interest in forward-looking solutions in the field of industrial water treatment. With Venture Stars, Wind Capital and Angel Invest, blue activity has secured three strategically valuable partners that bring not only capital but also extensive expertise and networks in the European CleanTech and industrial markets.
The successful seed round positions blue activity as one of the most promising players in the field of sustainable industrial technologies and lays the foundation for further growth and accelerated market penetration across Europe.
