We have been focused on sustainability long before it became fashionable.  Our systems-based approach to investing is founded on rigorous study and a pragmatic view of sustainability developed over more than a quarter century.

Our heavy operational and entrepreneurial background combined with intensive financial training drives value for both the fund and portfolio companies.  We have substantial experience working with sustainability-related companies, and have developed invaluable networks of entrepreneurs, investors, and executives throughout the world of sustainability.

Perhaps most importantly, we are deeply committed to rigor, excellence, and integrity.
