“Nikita and his team did a great job when I founded a GmbH to invest in a new start-up in Germany. They handled both the formation of the company and the negotiations for the participation. Beyond legal support, they even found a bank willing to work with me—something I wouldn't have managed on my own. Nikita was available at all times, and I always felt that he was fully behind me. Unreservedly recommended.”

Dr. Cortney Mittelsteadt, Hydrogen Pioneer and Entrepreneur, Boston
