Andrew Feinstein is Founding Director of Shadow World Investigations (formerly Corruption Watch), an NGO that undertakes path-breaking investigations into cases of grand corruption, corporate malfeasance and militarism, predominantly but not exclusively in the global arms trade. These case-studies are used to highlight the blurred lines between business and state, and to indicate the legal and political reforms that are needed to halt the corrosive impact of criminal and institutional corruption. Andrew was a former African National Congress (ANC) Member of Parliament in South Africa for 7 years before resigning in protest at the ANC's refusal to allow an independent and comprehensive inquiry into a multi-million dollar arms deal.

​Feinstein has written two books on the illicit global arms trade, The Shadow World and After the Party, which is a detailed account of his time spent within the ANC and the cover up involving the arms deal scandal. Feinstein was educated at King's College Cambridge, the University of California at Berkley, and the University of Cape Town and also participated in the London School of Economics Distinguished Visitors Programme. He regularly appears on a variety of broadcast media including BBC and Al Jazeera and authored the lead article in the SIPRI Yearbook 2011. Based on Feinstein's book, Johan Grimonprez directed the award winning documentary film Shadow World.

The documentary Shadow World aims to critically discuss the global arms trade by looking at complicity of governments, intelligence agencies and other invested actors. It premiered at the Tribeca Film Festival in April 2016. It won Best Documentary Film at the Edinburgh International Film Festival, the Seminci Film Festival, and won the Belgian Ensor Award for best Documentary Feature.
