Arabella Philanthropic Investment Advisors

What Arabella Philanthropic Investment Advisors does

Arabella Advisors was a Washington, D.C.-based philanthropic investment advisory firm that provided fiscal sponsorship services to nonprofit and social impact organizations. Its core offering was operational and administrative infrastructure spanning finance, HR, grants management, and compliance, enabling mission-driven clients to outsource back-office functions while retaining programmatic focus. The firm operated as a key operational node within a tightly coupled fiscal-sponsor ecosystem alongside New Venture Fund, Windward Fund, and Hopewell Fund, which together administered over $1.179 billion in resources for nearly 200 projects and more than 1,000 staff across policy, communications, and advocacy verticals in the United States and globally.

The business model centered on fee-based fiscal sponsorship servicing: Arabella housed the operations team that provided back-office support to multiple sponsor entities. Pricing and contract terms were not publicly disclosed, but the structural arrangement was that the three founding owners of the successor vehicle (NVF, Windward, Hopewell) collectively financed and benefited from Arabella's services. The company was privately held, headquartered in Washington, D.C., and served clients across all 50 U.S. states and international geographies.

On November 17, 2025, Sunflower Services — a newly formed Public Benefit Corporation capitalized by New Venture Fund (lead investor), Windward Fund, and Hopewell Fund — acquired Arabella Advisors' fiscal sponsorship servicing business along with its operations team and infrastructure. The acquisition was effective immediately, and Arabella Advisors ceased operations as an independent entity. CEO Himesh Bhise departed as part of the transition.
