@Rebecca Courtney thanks so much for taking the time :-) Some of those are tricky for a start-up, but I think a few free of charge beta sessions would get round that .

I'm INFP-T (turbulent mediator apparently). I have a professional role in the day job (barrister/trial lawyer) which requires performance and being at the forefront all the time. Yet I would have been the last person you would have expected to do that job. The trick is that (a) I know my stuff; (b) I am always fully prepared; c) I know someone else depends on me; and (d) the role has a set routine in which I know when I am expected to speak and there is space for me to do so, i.e. I don't have to assert my right to make myself heard because the role comes with the right to be heard and an expectation that I am. Thus I find I can set aside my diffident tendencies to play the role I'm undertaking. I think as facilitator it is much the same - I would put my metaphorical facilitator hat on and exercise the right that comes with the role, having set down strong ground rules at the start.

@Johannes Berner In some ways perhaps, but my point is that, for me at least, having a role with a defined function enables me to step outside my personal bubble and occupy a professional role for a time. For some that may help.
