Sixteen Thirty Fund

What Sixteen Thirty Fund does

Sixteen Thirty Fund is a 501(c)(4) nonprofit organization founded in 2009 and headquartered at 1828 L Street NW, Suite 400-B, Washington, DC. It operates as a fiscal sponsorship platform that provides legal, tax-exempt, and administrative infrastructure—including legal, HR, accounting, payroll, and compliance services—to enable progressive nonprofit projects and advocacy campaigns to launch within weeks rather than months or years. The organization does not develop a proprietary technology product; its core operational technology is the fiscal sponsorship framework itself, which wraps new public-interest organizations under its existing legal entity.

The fund's core "product" is its Fiscal Sponsorship Services platform (sixteenthirtyfund.org/our-approach/). It receives donations from foundations and funders on behalf of sponsored projects and provides back-office operational support so project leaders can focus on their core missions. As of the input data, it supports 110+ sponsored projects across all 50 US states, has administered 10,237 grants, and draws from a base of 500+ donors. Sponsored projects span issue verticals including voting access and civic participation (America Votes, LUCHA), climate (League of Conservation Voters), healthcare access (Health Care Voter), gun violence prevention (Giffords), paid family leave, rural civic engagement, and economic equity.

The business model is donation- and grant-funded rather than commercially priced. As a 501(c)(4), the organization can accept unlimited anonymous contributions (donations are not tax-deductible). Revenue sources include foundation grants and large individual donors—most notably Swiss billionaire Hansjörg Wyss, who directed $27M through the fund in the 2024 election cycle as part of $57M in total progressive spending. The organization is part of the Arabella Advisors "dark money" network and is governed by a board under President Amy Kurtz. Go-to-market is sales-led and inbound: prospective projects approach the fund for fiscal sponsorship, and the fund screens for alignment before onboarding. Distribution is single-country/domestic (United States only). The organization is currently subject to an ongoing House Oversight Committee investigation and a 2025 Nebraska Attorney General lawsuit alleging illegal foreign-funded spending on ballot initiatives, both of which represent material regulatory risk to its operating model.

Direct peers

• Hopewell Fund: Another Arabella Advisors-affiliated fiscal sponsor offering 501(c)(3) sponsorship for progressive projects. Co-defendant in the Nebraska lawsuit and operates the same fiscal-sponsorship model as STF.
• Haymarket Fund: Arabella Advisors-affiliated fiscal sponsor providing operational infrastructure to progressive movement projects. Operates the same fiscal-sponsorship model as STF within the same broader network.
• North Fund: Progressive 501(c)(4) connected to the donor-advised fund and fiscal-sponsorship ecosystem that channels major-donor funding to advocacy groups. Comparable in mission and structure to STF.
• Berger Action Fund: Co-defendant with STF in the Nebraska foreign-money lawsuit and part of the broader progressive dark-money network. Engages in direct advocacy and ballot-initiative funding comparable to STF's sponsored projects.
• New Venture Fund: Part of the Arabella Advisors network and a fellow fiscal sponsor serving progressive public-interest projects with 501(c)(3) status. Co-defendant with STF in the Nebraska lawsuit and provides very similar fiscal-sponsorship infrastructure.
• Windward Fund: Arabella Advisors-affiliated fiscal sponsor providing 501(c)(3) status to progressive public-interest projects. Operates the same fiscal-sponsorship model as STF within the same donor network.
• Tides Foundation: One of the largest fiscal-sponsorship platforms in the US, providing 501(c)(3) status to hundreds of progressive projects. A direct competitor for sponsored-project relationships and donor pass-through, though operating under 501(c)(3) rather than 501(c)(4).

Emerging players

• The Fairness Project: Progressive organization that funds ballot initiative campaigns on economic issues. Co-defendant in the Nebraska lawsuit alongside STF and similarly focuses on direct advocacy rather than pure grantmaking.

Broad incumbents

• Arabella Advisors: The consulting and advisory firm that connects STF, New Venture Fund, Hopewell Fund, and other fiscal sponsors to progressive donors. Operates as a broader ecosystem coordinator rather than a direct fiscal sponsor itself.
• Open Society Foundations: A large progressive grantmaking foundation funding many of the same issue areas (democracy, equity, climate). Operates at significantly larger scale than STF and funds rather than fiscally sponsors, but overlaps in grantee base.
