The Arlene & Michael Rosen Foundation

What The Arlene & Michael Rosen Foundation does

The Arlene & Michael Rosen Foundation (AMRF) is a private family foundation founded in 2015 and headquartered in Santa Barbara, California, that deploys trust-based philanthropy to support community-led health and wellness initiatives. The foundation's sole core product is the GO Grants program, which provides unrestricted, flexible core operating support to small grassroots nonprofit organizations through a streamlined five-minute application and minimal reporting requirements (replaced by "coffee conversations" rather than formal written reports). GO Grants are deployed in fixed cohorts of 25 per region across three active geographies: Mendocino County (launched 2023), San Diego County (launched 2024), and Oregon. Regional directors embedded in each community identify and build relationships with grassroots leaders, and AMRF supplements grants with non-monetary support including help accessing government funding, connections to other funders, and convening via community events.

AMRF's business model is foundation grantmaking rather than commercial revenue generation. The foundation is funded by an undisclosed family endowment, and grants are deployed from endowment returns and principal. The go-to-market motion is community-led and event-driven: regional directors (Laura Hamburg, Lucky Michael, Whit Guerrero) serve as the primary touchpoints and build pipelines through local relationships, membership on funder collaboratives (RTFH, Funders Together, Oregon Funders for Housing Justice), and community gatherings. The foundation operates with a small distributed team of 1-10 staff under a co-leadership model (Co-Executive Directors Jason Satterfield and Danielle Wildkress) and has publicly committed to sunsetting within seven to ten years.

AMRF has no proprietary technology platform; its technical surface is limited to a WordPress website (amrf.org), a basic online grant application form, and an Instagram social presence. The foundation's competitive differentiation rests on its trust-based approach, which eliminates traditional philanthropic barriers such as complex applications, restricted funding, and heavy reporting, and on the lived-experience credibility of its team, most of whom joined from outside philanthropy with direct service backgrounds.
