Arthur Wood - Arthur Wood is a recognised innovator in social finance. Prior to his current roles with the World Sanitation Financing Facility (convener and chairman) and Total Impact Advisors (founding partner), he was for over four years a Leadership Group Member and SVP of Ashoka - the world's largest supporter of social entrepreneurs - where he was the Global Head of Social Financial Services with three years in DC and New York. He has been instrumental in getting a number of major global financial services firms to enter the business of social investing to change the way social capital is allocated and deployed - increasing the flow and efficiency of finance to the social sector. He has also been extensively involved in the conceptualisation and creation of new legal hybrid structures to encourage social investment - most notably the L3C in the US (law in 10 US jurisdictions as of writing) and the SELLP in the UK. He launched the Ashoka SIE programme (social finance) and advised a range of broader social entrepreneurs in financing structures - this has included conceptualising and launching a fund noted as "one of the top twenty ideas in new philanthropy" by Fast Company Magazine. Arthur is recognised as the father of the new social impact bond. Read more
