Michael W. Sonnenfeldt is an entrepreneur, investor, and philanthropist. In the 1980s, he conceived and initiated the Harborside Financial Center in Jersey City, NJ, the world's then-largest commercial renovation. He subsequently founded and led Emmes & Company, a real estate investment boutique specializing in buying distressed portfolios. He has decades of experience in the renewable energy sector, beginning with a solar company he built, SOL, which was eventually sold to Carmanah Technologies Corp., a public Canadian company that manufactures and distributes solar products and systems. He holds Bachelor’s and Master’s degrees in Management from the Massachusetts Institute of Technology. Following his entrepreneurial success, Michael founded Tiger 21, the premier learning and investment network for high-net-worth individuals, creating a forum to discuss his shifting priorities of family, legacy, and investment with peers.

Michael has also been actively involved for the last twenty-five years in numerous non-profit organizations focused on the environment and climate change, national security, Middle East peace, international peacekeeping, the US/UN relationship, and communal development. His passion for these causes guides his business and philanthropic work, and shapes the mission of MUUS to invest in a more livable and sustainable future. When Michael isn’t in the office, he dedicates time to his other passions; photography, Japanese art, sailing, and woodworking.
