We are sustainability experts.

At MUUS we recognized early that rapidly improving economics in climate tech, and demand for decarbonization, would lead to great investment opportunities. We leverage sustainability experience across multiple sectors to pursue growth and impact opportunities.

We are entrepreneurs.

We have launched and led public and private companies, and take pride in our radically flexible approach. We take controlling or minority positions and invest at any stage of a company's evolution. As entrepreneurs, we help companies reach their full potential sometimes over long timeframes or through complex pathways to success.

We are connectors.

We have built an unparalleled network of business, policy, and academic professionals over decades of close collaboration across sectors. This includes our association with the world’s premier network of high-net-worth individuals at Tiger 21. We enable companies to find strategic partners that drive growth, and connect them to the right people at the right time.
