Create a list of potential board members from the organisation’s network, or post calls for members within a larger network. For example at relevant professional foundations.
Reach out to the candidates, for example by one of the following ways:
Have a meeting (lunch/dinner) with all candidates, tell them about the organisation and what it is looking for in board members.
Have individual meetings or send letters of interest.
Invite potential members to an advisory board before assigning them on to the board.
