 Mosaico Management LLC seeks to identify, develop, and execute investment strategies with superior risk-adjusted returns that demonstrably benefit society and the natural environment. Launched in 2015, the firm was created based on blue moon fund’s long history of mission-driven investing and endowment management. Our vision is to expand the efficient frontier by elevating sustainability and environmental impact to the level of significance traditionally placed solely on expected return and volatility.
