In this episode, I speak with Michael W. Sonnenfeldt, Entrepreneur, Investor, and Philanthropist on his life's journey and the future of climate investing and climate startups.
Michael W. Sonnenfeldt is an accomplished entrepreneur, investor, and philanthropist. With a visionary mindset, he spearheaded the groundbreaking transformation of the Harborside Financial Center in Jersey City, NJ during the 1980s, making it the largest commercial renovation project of its time. Michael went on to establish and lead Emmes & Company, a distinguished real estate investment boutique specializing in the acquisition of distressed portfolios.
Having an extensive background in renewable energy, Michael's journey in this sector began with the creation of SOL, a solar company that he built from the ground up. Eventually, SOL was acquired by Carmanah Technologies Corp., a reputable Canadian company engaged in the manufacturing and distribution of solar products and systems. His knowledge and expertise in renewable energy span over several decades.
Educationally, Michael holds both Bachelor's and Master's degrees in Management from the Massachusetts Institute of Technology, further enhancing his foundation for success. Building upon his entrepreneurial achievements, he founded Tiger 21, an esteemed learning and investment network catering to high-net-worth individuals. This platform offers a unique space for peers to engage in open discussions about family, legacy, and investment, allowing Michael to share his evolving priorities.
Michael's dedication extends beyond his professional endeavors. Over the past twenty-five years, he has actively contributed to numerous non-profit organizations focusing on crucial causes such as the environment, climate change, national security, Middle East peace, international peacekeeping, the US/UN relationship, and communal development. His commitment to these important issues influences both his business and philanthropic work, shaping the mission of MUUS to invest in a more sustainable and livable future.
