Who They Are
Arabella Advisors is the operational hub of the Democratic Party’s dark money infrastructure—a for-profit consulting firm that manages seven interconnected 501(c)(4) nonprofits collectively deployed to distribute $1.7B+ across electoral campaigns, judicial appointments, ballot measures, and policy advocacy while maintaining permanent donor anonymity. Founded by Eric Kessler in 2007, Arabella functions as the Democratic equivalent to Leonard Leo’s Federalist Society apparatus: it doesn’t raise money itself, it structures how anonymous wealth deploys political power. The firm collected $220M+ in management fees (2020-2024) by operating what it calls “fiscal sponsorship networks”—essentially, it manages other organizations’ money while those organizations maintain no independent disclosure obligations. InfluenceWatch: Arabella Advisors (Tier 3) The architecture allows anonymous donors to write one check to Arabella, which then distributes funds to dozens of separate advocacy vehicles, ballot campaigns, and “pop-up” organizations created for single election cycles and dissolved after victory or defeat. Donors never appear in public records.
What They Want
Arabella’s stated mission is “progressive advocacy and infrastructure.” What that means operationally: Democratic Party dominance maintained through systematic opacity. The five primary “pop-up” nonprofit vehicles—Sixteen Thirty Fund, New Venture Fund, Windward Fund, Hopewell Fund, North Fund—are deployed to:
- Ballot measure campaigns — abortion access (post-Dobbs), climate policy, voting rights expansion
- Electoral infrastructure — temporary state-level advocacy organizations created for Senate/House races, dissolved post-election
- Judicial appointment warfare — funding Demand Justice’s confirmation battle operations ($50M+ 2018-2024)
- Democratic Party institutional protection — funding organizations that coordinate with DNC/DCCC messaging and endorsement strategies
- Donor anonymity as product — the fundamental service Arabella sells is legal opacity. Wealthy Democrats can deploy $10M+ in political campaigns without appearing in any public record.
The business model depends on perpetuating exactly what Democratic political rhetoric condemns: Citizens United legalized dark money. Arabella institutionalized it as party infrastructure.
How the Structure Works
The Arabella Seven — Interconnected 501(c)(4)s:
| Vehicle | Year Created | 2024 Spending | Primary Function | Dissolution Pattern |
|---|---|---|---|---|
| Sixteen Thirty Fund | 2010 | ~$311M | Flagship fiscal sponsor; judicial, ballot, electoral | Permanent |
| New Venture Fund | 2010 | ~$150M+ | Healthcare, education, climate sub-grants | Permanent |
| Windward Fund | 2008 | ~$120M+ | Climate, environment, electoral (competitive races) | Permanent |
| Hopewell Fund | 2013 | ~$80M+ | Democracy/voting, LGBTQ+, reproductive rights | Permanent |
| North Fund | 2012 | ~$100M+ | Community organizing, immigrant rights | Permanent |
| Telescope Fund | Created later | ~$50M+ | Technology, innovation, misc. | Permanent |
| Impetus Fund | Created later | ~$40M+ | Economic/labor justice initiatives | Permanent |
Total combined raised 2024: $1.5B+ (represents roughly 12-15% of all Democratic political spending in a cycle year). Arabella Advisors - Nonprofit Quarterly (Tier 2)
Operational mechanics — How donor anonymity is preserved:
-
Anonymous donor writes check to Arabella-managed 501(c)(4) (e.g., Sixteen Thirty Fund) with no contribution limits and zero donor disclosure requirements.
-
Arabella distributes funds as grants to project organizations, which can be:
- Permanent advocacy groups (Demand Justice, various think tanks)
- Temporary “pop-up” organizations created for single election cycles
- Other nonprofits with separate 501(c)(4) status
-
Pop-up organizations operate fully during one election cycle, then dissolve. Examples:
- Piedmont Rising (North Carolina, 2020) — created to target Senate races, dissolved post-election
- Advancing Arizona (2020) — state-specific Senate operations, temporary entity
- Rocky Mountain Values (Colorado, 2020) — defunct after 2020 election
- Health Care Voter (2020) — created to run ACA defense ads, then shuttered
- Protect Our Care (2020) — single-cycle entity, no independent legal existence
-
Grants flow through fiscal sponsorship agreements — the pop-up organization files no separate tax return, maintains no separate board, and discloses nothing. To the public, the donor trace stops at Arabella.

Demand Justice case study — Fiscal sponsorship to separation:
Demand Justice operated as a Sixteen Thirty Fund sub-project (2018-2021) with zero separate disclosure. It received $50M+ in funding while filing no independent 501(c)(4) paperwork—all funds routed through Sixteen Thirty’s structure. In 2021, Demand Justice spun off into separate 501(c)(4) status, gaining its own filing requirements and separate donor disclosure obligations. Same operation, different legal wrapper. The point: Arabella controls the infrastructure regardless of whether subsidiaries remain formally dependent or formally independent.
Eric Kessler — The Architect
Eric Kessler founded Arabella Advisors in 2007 after working at Environmental Defense Fund. He positioned himself as a “progressive infrastructure builder” but functionally created the Democratic Party’s most sophisticated dark money apparatus. Unlike Leonard Leo (whose Federalist Society is a nonprofit that he chairs), Kessler operates as a for-profit consultant extracting $220M+ in fees from a nonprofit ecosystem he designed. This is capital accumulation through political infrastructure management. Kessler maintains low public profile deliberately—there are no TED talks, no op-eds, no public appearances. He is to Democratic dark money what Leo is to Republican dark money, but with far less name recognition. Tablet Magazine: Inside Arabella Advisors (Tier 2)
2025-2026 Update — Rebranding, Chorus Collapse, and Continued Expansion
Arabella → Sunflower Services: Before the 2026 midterms, Arabella Advisors rebranded as Sunflower Services — a name change widely interpreted as an attempt to reduce public recognition of the organization’s dark money profile after years of investigative journalism and Congressional scrutiny. The underlying structure (seven interconnected 501(c)(4)s, Eric Kessler’s management model, $1.5B+ annual deployment) remains unchanged. House Oversight: Comer Continues to Investigate (Tier 1)
Chorus Influencer Program Collapse: The House Oversight Committee (Chairman James Comer, R-KY) launched investigation in November 2025 into Sixteen Thirty Fund’s “Chorus Creator Incubator Program” — a network that paid social media influencers to promote Democratic messaging under contracts that explicitly prohibited disclosing payment or including required political advertising disclaimers. Chorus was structured to function as political advertising while claiming nonprofit advocacy exemption.
After receiving the Oversight Committee inquiry, Sixteen Thirty Fund severed active ties with the Chorus program. On November 21, 2025, records show the filing of a new domestic nonprofit called Creator Collective — appearing to be a rebranded successor vehicle preserving the influencer-payment infrastructure after the Chorus program collapsed under scrutiny.
The structural irony
A network built on opacity — no donor disclosure, no ad disclaimers, no public accountability — responded to Congressional scrutiny by creating a new entity with a different name. The mechanism survives. The name changes. This is the Arabella pattern: when infrastructure becomes publicly legible, rebrand and continue.
Texas Senate Primary 2026: The Sixteen Thirty Fund’s operational pipeline was documented in the March 3 Texas Democratic Senate primary: Sixteen Thirty → Government that Works PAC ($4M) → Lone Star Rising PAC ($3.75M) → Talarico campaign support. Talarico defeated Rep. Jasmine Crockett 53–46%, with a spending advantage of roughly $15M (Talarico-side) to $3M (Crockett-side). Full documentation in Sixteen Thirty Fund note.

Known Donor Flows Through Arabella
Unlike anonymous structures that hide everything, some Arabella donors have become partially documented:
- George Soros / Open Society Foundations — $125M+ to Arabella network (2018-2024), with significant co-funding into Sixteen Thirty, Demand Justice, and ballot measure campaigns
- The Mellon Foundation — $40M+ to Democracy Alliance (which coordinates with Arabella), funding “expanding voter participation”
- The Tides Foundation — $15M+ documented to Arabella-managed funds (fiscal sponsor relationships, not direct Arabella board giving)
- Individual mega-donors — estimated $200M+ flows through “bundled” anonymous contributions to Sixteen Thirty (individual identities never disclosed)
- Hansjörg Wyss — Wyoming mega-donor, estimated $100M+ to Arabella conservation/climate funds (Windward Fund specifically)
The point: some funder identities have leaked through investigative journalism, but Arabella’s fundamental purpose is that they shouldn’t. ProPublica: Dark Money Groups Are Reshaping Politics (Tier 2)
The Mirror Image of Leonard Leo / Marble Freedom Trust
Leo’s structure (Republican right):
- Marble Freedom Trust (501(c)(4), tax-exempt) funnels anonymous money to Federalist Society judges and related infrastructure
- Federalist Society itself is public-facing; Leo’s dark money infrastructure is supplementary
- DonorsTrust acts as fund manager (distributes money to Republican causes)
- Total spending: ~$548M annually (2024 cycle)
Arabella’s structure (Democratic left):
- Sixteen Thirty Fund, Windward, New Venture, Hopewell, North (five 501(c)(4)s) funnel anonymous money to Democratic causes
- Each “fund” serves specific policy verticals but all route through Arabella management
- Arabella itself is the administrative center (for-profit firm extracting fees)
- Total spending: ~$1.5B annually (2024 cycle)
Structural similarities:
- Both operate 501(c)(4)s to claim tax-exempt status while spending unlimited money politically
- Both create temporary organizations to hide donor connections to multi-cycle spending patterns
- Both use fiscal sponsorship to obscure the paper trail from anonymous donor to political campaign
- Both are defended by their respective parties as necessary counterweights to opposition dark money
- Both maintain that donor privacy is a “free speech” issue
Structural differences:
- Leo’s apparatus targets judicial appointments; Arabella’s is more horizontally distributed (ballot measures, Senate races, judicial, etc.)
- DonorsTrust requires funder disclosure within the fund (privacy, but within a known group); Arabella requires zero disclosure to anyone
- Arabella scales larger (2-3x Leo’s annual spending) because Democratic donor class has more liquid capital
The structural equivalence is absolute: Democrats use identical mechanisms to what they politically condemn. The rhetoric: "We must overturn Citizens United and restore democracy." The practice: deploying unlimited anonymous money through sophisticated opacity structures.
Connected Policy Areas and Contradictions
- Judicial appointments — Demand Justice runs court-capture operations while Democrats publicly position themselves as anti-Citizens United
- Ballot measures — abortion access (post-Dobbs) bankrolled through Arabella structure
- Climate spending — Windward Fund manages millions in environmental advocacy
- Voting rights — Hopewell Fund manages “democracy” ballot initiatives
- Immigration — North Fund’s community organizing work
- Party coordination — Sixteen Thirty’s grants align with DNC/DCCC messaging in ways that blur independence
The core contradiction: Democrats built their political identity on Citizens United opposition, then institutionalized Citizens United as party infrastructure. Arabella Advisors is what that institutionalization looks like operationally.
