Anti-Slavery

What Anti-Slavery does

Anti-Slavery International is a UK-registered charity and Company Limited by Guarantee (charity number 1049160), founded in 1839 and headquartered in London at The Foundry, 17 Oval Way, SE11 5RR. It is the world's oldest international human rights organization, working to eliminate all forms of modern slavery — including human trafficking, forced and bonded labour, descent-based slavery, child slavery, forced marriage, and domestic servitude — affecting an estimated 50 million people worldwide. Its work spans survivor-centered programmatic support, policy advocacy, research, coalition-building, and supply chain advisory, delivered through a small team of 11–50 employees and a global network of partner NGOs, survivor-led organizations, and coalitions in over 20 countries across West/Central/East Africa, South/Central Asia, the Middle East, South America, East Asia, and the Indian Ocean.

The organization's product portfolio includes the bi-annual Reporter magazine (published since 1840), free educational resources and lesson plans, downloadable research reports and policy briefs, the Recovered Histories interactive site on the Transatlantic Slave Trade, a modern slavery awareness quiz, the Climate Change and Modern Slavery Hub knowledge platform, bespoke business advisory services aligned with the UN Guiding Principles on Business and Human Rights, and referral integration with the UK Modern Slavery Helpline. Underlying technology is intentionally non-proprietary; the organization's capabilities rest on research, advocacy, and coalition coordination rather than software platforms, APIs, or AI systems.

Its revenue model is a hybrid charity funding structure comprising individual donations and memberships, institutional and statutory (government) grants, corporate partnerships (including with companies like ASOS), trust and foundation funding, and fundraising through challenge events such as the London Marathon and London Landmarks Half Marathon. Go-to-market is community-led and survivor-centered, combining grassroots movement building, parliamentary and international policy advocacy (notably contributing to the UK's 2015 Modern Slavery Act and the EU draft forced labour regulation expected by 2026), and direct engagement with enterprises on supply chain due diligence. Disclosed cost efficiency stands at 83p of every £1 spent on charitable activities (22/23 annual report).

Direct peers

• International Justice Mission (IJM): Global non-profit focused on rescuing victims of modern slavery and trafficking and bringing perpetrators to justice, with a survivor-centered advocacy model nearly identical to Anti-Slavery International's approach.
• Freedom Fund: Specialist anti-modern-slavery foundation funding survivor-led interventions in high-prevalence countries; shares Anti-Slavery's hotspot strategy, survivor-centered ethos, and grantmaker/advocate hybrid model.
• Walk Free (Minderoo Foundation): Publishes the Global Slavery Index used widely by governments and corporates; competes directly with Anti-Slavery for policy influence, corporate partnerships, and grant funding in the modern-slavery category.
• Polaris Project: US-based anti-human-trafficking organisation operating the National Human Trafficking Hotline and running survivor advocacy programs that closely mirror Anti-Slavery's helpline integration and survivor-services work.
• Stop the Traffik: Global coalition-based NGO preventing human trafficking through awareness, data sharing, and partnerships; overlaps heavily with Anti-Slavery's movement-building and coalition-driven GTM.

Broad incumbents

• Human Rights Watch: Larger, broader human-rights organisation that publishes influential reports on bonded labour, child marriage, and state-sponsored exploitation; competes for statutory grant funding and policy influence with Anti-Slavery.
• Amnesty International: The largest individual-donor-funded human rights organisation globally; competes directly with Anti-Slavery for membership donations, magazine-style fundraising, and UN/EU advocacy access.

Emerging players

• Verité: Specialist supply-chain due-diligence NGO advising corporates on forced labour risk; overlaps tightly with Anti-Slavery's business advisory service offering and partner NGO for capability gaps.
• KnowTheChain: Investor- and corporate-facing research platform benchmarking company disclosures on forced labour; competes with Anti-Slavery's advisory positioning in the responsible-business segment.

Others

• International Labour Organization (ILO): UN agency setting the global standards (e.g., ILO Forced Labour Convention, Protocol of 2014) that Anti-Slavery advocates to ratify; an institutional counterpart rather than a competitor, often collaborating on research and campaigns.
