About Us

About Us

The RFSI team brings more than two decades of experience in agriculture, food systems, investing, research, media, and events.

Our goal is to work across diverse groups of funders and stakeholders to mobilize more capital for regenerative food and agriculture projects. We also aim to expand the distribution of information and tools that communicate the financial, ecological, and social benefits of investments in a regenerative food system.

Capital, from many diverse sources, is critical to the expansion of a regenerative food system.

We hope you will join us in growing this crucial community.
