HOST

What HOST does

HOST (formerly Climate 2025, trading as 'ally for action') is a UK-registered nonprofit operating as a fiscal sponsorship and operational infrastructure provider for climate and social justice movements. Founded in 2020 and rebranded to HOST in 2025, the organisation enables change-makers to receive, manage, and disburse funds without holding their own legal entity, layering income management, grant management, multi-currency operations in GBP/USD/EUR, contractor engagement across 80+ countries, tax compliance, risk management, and real-time financial reporting on top of a core project hosting package. Its proprietary platform, HOSTHub, provides real-time dashboards for income, expenses, and grants across 90+ hosted movements and 125+ grantmakers, with 475 donor contracts delivered and £35M+ in project operations managed since inception.

The core commercial offer is the Standard Project Hosting Package, priced as a percentage of managed funds, supplemented by two hosted grantmaking products (HOST Action Funds and HOST Collective Funds) and a modular add-on suite including charitable sponsorship (UK/US/NL/SW/SI), Stripe and PayPal donation page integration, global employment and HR, multi-currency hosting, payment cards, and trading services. HOST monetises primarily through managed-services fees, with add-ons and standalone services priced transparently on a tailored basis. Distribution is exclusively direct and relationship-based, funnelled through Expression of Interest forms and consultation with the Community Support Lead. The 2024 Acter partnership extends the stack into secure digital organising for movements operating under surveillance or censorship.

HOST serves three horizontal customer segments: change-makers and grassroots movements, donors and funders seeking compliant cross-border disbursement, and intermediaries and service providers co-delivering infrastructure. Named clients include Climate Clock, Culture Declares Climate and Ecological Emergency, Debt for Climate, Loss & Damage Collaboration, and Climate Declares Emergency. HOST has co-founded five civil society platforms (the Global Citizens' Assembly, The Movements Trust, Foundations Earth, The Climate Activist Speaker Fund, and Social Movement Coaching), operates in 104+ countries across six continents, and grew turnover from £1.9M in 2021 to approximately £10.3M in 2024 with a 13-person remote team headquartered in the UK.

Direct peers

• RSF Social Finance: Fiscal sponsor and impact-focused financial services provider supporting social enterprises and nonprofits. Comparable in providing integrated financial infrastructure for values-aligned organizations, including lending and grants.
• Astraea Lesbian Foundation for Justice: Global movement grantmaker and fiscal sponsor for LGBTQI human rights groups, especially in the Global South and restricted environments. Highly comparable in mission, hosted grantmaking model, and high-risk operating geographies.
• Tides Foundation: One of the largest US-based fiscal sponsors hosting climate, justice, and progressive projects with multi-currency payments and philanthropic infrastructure. Directly comparable in fiscal sponsorship model and movement-aligned mission, though larger and US-anchored.
• Thousand Currents: Hosts and regrants funds to grassroots movements in the Global South with participatory grantmaking. Highly comparable given HOST's focus on majority-world change-makers, hosted grantmaking, and participatory collective funds.
• Mama Cash: Funds and hosts women's, girls', and transgender rights movements globally, including via regranting and fiscal hosting. Comparable in operating model and movement-amplification focus, with HOST's recent rebrand broadening similar reach.
• Global Greengrants Fund: Environmental justice regranting organization that makes small grants directly to frontline groups worldwide. Closely comparable to HOST's regranting model and climate/environmental mission, with overlapping donor ecosystems.
• Open Collective Foundation: US-based fiscal sponsor for open-source and community-driven projects using transparent financial infrastructure. Comparable in fiscal sponsorship model and tech-enabled transparency, though focused on digital/OSS communities.
• Groundswell Fund: Hosted grantmaking fund supporting grassroots movements for reproductive justice, racial justice, and gender equity. Comparable in participatory grantmaking approach and movement-amplification focus.

Broad incumbents

• National Philanthropic Trust: Major donor-advised fund sponsor and grantmaking infrastructure provider. Comparable in providing philanthropic hosting infrastructure, but at much larger scale and with broader, less movement-specific positioning.
• Schwab Charitable Fund: Large donor-advised fund sponsor with billions in assets under management and broad nonprofit funding scope. Comparable in distributing philanthropic funds to nonprofits, but operates as a mainstream DAF rather than a movement-specific fiscal sponsor.
