Aims and activities

The Social Impact Investors Group (SIIG) exists to support foundations interested in starting or currently undertaking social impact investing.

The SIIG runs a free programme of market information days, every six to eight weeks, to raise awareness about social impact investment opportunities from charities, social enterprises, social purpose organisations and social impact funds. The days are mutually supportive with a focus on learning; newer investors learn from the questions posed by their more experienced peers, and those presenting are able to benefit from feedback on their ideas*.

The SIIG also offers a paid-for membership programme of learning sessions and resources. Learning events are open to all SIIG members’ staff and trustees, covering topics such as how to assess and balance financial and social return, how to carry out due diligence, and exploring different types of investment. Members can access a toolkit of templates and exemplars for those establishing or running a social impact investing programme, and signposting to a range of learning events run by external partners.

A full list of SIIG events is available on ACF's events page. 

*All attendees must self-certify to attend. The SIIG does not go further than providing a means for communication, any follow-up interactions or information shared relating to particular transactions is not the responsibility of the SIIG. 

How to get involved

Membership of the SIIG is open to foundations and other organisations with a charitable or social mission with investible assets.  To find out more about joining, please contact Gemma Cartwright at ACF.
