SIB Pioneers Network

The SIB Knowledge Club is a network of small local groups of practitioners who have undergone, or are undergoing, the process of developing a SIB. It is open to practitioners in both the public and voluntary sectors. 

The network was launched with three simultaneous regional events in May 2018, jointly organised by the GO Lab, The National Lottery Community Fund and Ecorys. You can read some of the insights gathered at these launch events here.

Local Knowledge Clubs

Participants expressed a strong desire to come together face to face in a small local groups, and learn from each other. They also expressed a desire to go deeper on some of the technical aspects of SIB development, like developing an outcomes framework. Our proposed approach going forward combines both of these. Local leads across the country will put together small groups of SIB practitioners, who will come together periodically and choose a short 2-3 page learning resource to discuss from a carefully curated library. You can read more about why we chose this approach, and how it will work, here.

Should you wish to join a knowledge club, the regions and the key contacts who will be supporting the local leads are as follows:


Each of the local leads will get to choose from a range of resources developed by the GO Lab and our partner organisations, and Knowledge Club members can also develop their own resources or make suggestions for new materials to be developed by the GO Lab. 

Why use social impact bonds?
