It’s hard to say which came first – our partnership or our expertise in clean technologies—they’re so closely interrelated. Our Partners have a long and varied history of working together in energy and cleantech, which predates the company’s founding (in 1998) by 30 years.

We partner with management teams in the same way we partner with each other, drawing on our collective strength. As a result, our portfolio companies have access to our deep and wide-ranging network of innovators, policy makers and business leaders.
