Weeefiner has reached a significant milestone. We have been included in the 2025 Deloitte Technology Fast 50 Finland list, which brings together Finland’s fastest-growing technology companies. We ranked 17th, a recognition not only of the company’s growth but also of the dedication and hard work of our entire team.
Being part of the Technology Fast 50 list reflects real, measurable growth. Companies do not need to apply for the program; the ranking is based on their financial statements. Growth is measured by revenue development over a four-year period (2021–2024). This demonstrates that the work we’ve put in has produced tangible results. It is a privilege to be recognized among Finland’s impressive technology companies.
CEO Mikko Hänninen celebrates the great ranking.
“This is a great reminder to pause for a moment and appreciate how far we have already come in developing industrial water treatment and metal recovery solutions,” says Mikko Hänninen, CEO of Weeefiner.
Weeefiner’s mission is to build a future where valuable metals in industrial wastewater can be efficiently recovered and reused. Our groundbreaking 4D Sieppari® technology provides a sustainable and economically viable solution for minimizing industrial environmental impacts while improving resource efficiency.
Growth does not happen by itself. The commitment of our team, the trust of our customers, and the support of our partners have all played a crucial role in our journey. We want to thank all those who support us – you make our growth possible.
