Social investors can provide the required up-front funding for new interventions and services delivered by charities and social enterprises, knowing their returns will only be made if the intervention achieves specific improved social outcomes. Examples of such programmes are: working with vulnerable children to improve educational attainment, and providing family therapy to avoid vulnerable adolescents being taken into local authority care.

The  Bridges Social Impact Bond fund was launched in April 2013 with Big Society Capital as cornerstone investor, alongside Omidyar Network and Panaphur, and a co-investment agreement with the Bridges Social Entrepreneurs Fund. The fund provides investment and support to charities and social enterprises delivering  intervention programmes which significantly improve social outcome

  • A clear social mission
  • A strong management team
  • The ability to deliver highly impactful social interventions
  • The ability to robustly monitor and proactively manage the social outcomes delivered by these programmes

Each investment made by the fund will be:

  • up to £3 million to deliver an outcomes-funded intervention programme
