The Rudolf Steiner Foundation (better known today by its business name RSF Social Finance) is a financial services organization which receives its funding from a group of investors and uses its resources to issue loans and grants to a variety of businesses and advocacy groups with left-of-center missions. 
RSF Social Finance invests in a variety of organizations, including those active in the arts and education. However, RSF Social Finance emphasizes its efforts on support for environmentalist organizations, particularly those in the food, animal liberation, and energy sectors.
RSF Social Finance screens businesses and non-profits seeking loans through “an extensive questionnaire,” which requires the applicant to provide details regarding its labor practices and positions on environmentalist questions. 
The Rudolf Steiner Foundation was created in 1938 as a treasury for the Anthroposophical Society in America, the American branch of the International Anthroposophical Society. The Anthroposophical Society is devoted to advancing the teachings of the philosopher, mystic, esotericist, and intellectual father of the controversial Waldorf Education System, Rudolph Steiner. The Rudolf Steiner Foundation is better known today by its public-facing, doing-business-as name, RSF Social Finance.  RSF Social Finance has undergone a drastic shift in its purpose, and no longer exclusively works to support the Anthroposophical society. 
Social Issue Loans
The criteria for receiving this class of loans, beyond submitting an organizational mission with a left leaning, includes being profitable or being capable of demonstrating profitability, requiring between $200,000 to $5 million in loans, and proof of annual revenue of $1 million or more. 
Businesses and non-profits with environmentalist missions which RSF Social Finance has provided loans to include Commons Energy, BlocPower, RecycleForce, and Malibu Compost. 
Businesses and non-profits with center-left food and agricultural policies supported by RSF Social Finance include: Veritable Vegetable, Sea to Table, Guyaki, Vermont Land Trust, Common Market, Equal Exchange. 
Food System Loans
Businesses and non-profits which expand the food infrastructure in the United States are issued loans ranging from $50,000 to $400,000. 
Businesses receiving loans include Cairnspring Mills, a flour mill which aims to increase small-scale, small supply-chain flour mills as a viable business model. 
Kevin Morse, the founder and CEO of Cairnspring Mills, was the director of The Nature Conservancy’s Puget Sound working Lands Program prior to creating Cairnspring Mills. RSF Social Finance provided Cairnspring Mills with a $300,000 line of credit to support the growth of Kevin Morse’s organization. 
Beyond loaning money to businesses and non-profits at a profit, RSF Social Finance on a far smaller scale makes grants, between $500 and $3,500 per organization, to left-of-center organizations. 
The 2018 grant recipient list included:
- Abarrotes Bondadosa, an organization which supports food-welfare programs by expanding the means by which SNAP recipients can expend their funds.
- Eyak Preservation Council, an environmentalist group organized to limit the commercial use of land and water in the interest of promoting wild-salmon habitats in Alaska.
- The Nashville Food Project, an organization which aims to expand non-profit access to land and connect refugees to the United States with jobs in agriculture.
