Removing from my budding startup team a highly motivated guy, bright, experienced in big companies... without damaging his ego AND without lying AND while being clear. If I can re-orient everyone I need to, as well as this guy until the end, I'd be so proud and happy! And I won't ever make enemies that way.

That was a very charged conversation emotionally, I was vulnerable and highly respectful, but still decisive and honest.

I refrained from exposing the case I had 'against' him to make the decision to move him from a potential cofounder role to an external advisory role. Instead, once decision was made, I committed for this to be as good as possible for everyone. I started bravely with the clear news, pointing out it had been my mistake to bring him on at that point.

I had taken serious time imagining his viewpoint. I talked about all the good he had brought to the project, for real, and all the good I valued about him, for real, and asked him to be an advisor (yes, he's been of value in that role, despite the hurt feelings).
