For more than 135 years, Castrén & Snellman has helped shape the Finnish business landscape. We are proud of that legacy – of the clients we have supported, the transactions we have enabled, and the legal standards we have helped define.
Building on that strong foundation, our partners came together to look ahead, understand how the market is evolving, and sharpen our focus on creating even greater impact and value for our clients.
Two things guided our work above all else. First, our clients expect strategic support and solutions that advance their business objectives. Second, AI is reshaping the legal profession, creating real opportunities for those willing to move boldly. Our strategy is our answer to both.
Partner and Chair of the Board Anders Forss says.
Backed by a strong full-service platform and leading legal expertise in relevant areas, we have a unique advantage in transactions. With the ambition to be even stronger, we are now sharpening our focus and accelerating the development of our transactional services.
Managing Partner Jarno Tanhuanpää emphasises the importance of acting as a proactive, solution-oriented partner that genuinely understands the clients’ business:
We are placing the client at the centre of everything. In transactions, our clients benefit from a seamless one-team experience, where our best experts across practices work together to deliver the strongest possible outcome for our clients. And we are leading the way in AI – driven not by the technology itself, but because it generates real, tangible value for the people and companies we serve.
All of this has to translate into a lasting advantage for our clients. That is the measure we hold ourselves to.
Our vision for 2030 is clear: to be the most client‑centric law firm in the Nordic region, combining a powerful full-service platform with leading expertise in transactions. We have the expertise, the spirit and the determination to get there.
The future belongs to those who are prepared. Our commitment is to make sure our clients always are.
We are Your Advantage.

We acted as Finnish law legal adviser to the lenders and the export credit agencies in connection with the EUR 514.4 million green project financing for the development and construction of Easpring Finland New Materials Oy’s cathode active material (CAM) manufacturing plant in Kotka, Finland.

Once the first phase of the project is operational, the Kotka facility is expected to produce approximately 60,000 tonnes of cathode active material annually, making it one of the largest CAM production plants in Europe and supplying leading battery manufacturers across Europe.
