• About Us

It’s about us, empowering you.

We believe investing is more than a transaction, it’s a personal stake in the future. In 2000, we set out to build an investment firm committed to sustainability. We chose this path because it was the right thing to do and because we were convinced it was simply a better way to invest.

Our idea has grown into a nationwide community of clients ranging from individuals to foundations. Along the way, we’ve witnessed the performance and impact of sustainable investing and wondered how to empower investors everywhere to become part of this legacy.

The answer is EarthFolio, the world’s first automated investing service dedicated to sustainable investing. Built with the same ethos that’s inspired us from the start, EarthFolio features world-class funds, personal asset allocation, and ongoing portfolio monitoring, all at a fraction of the typical investment and cost.

Investing sustainably has never been easier or more meaningful. We invite you to join us as we enter a new era of proactive investing—one powered by you.
