What does his staff being male have anything to do with how he runs his fund?
For one, there is research on all-male trading and investment teams taking more risk than mixed-gender teams. For another, we have documented cases of overt sexism among SoftBank-backer founders (most notoriously, Adam).
When I met Lydia Jett I assumed that she is a woman but I did not ask.
On this, I have no information. Was just justifying citing an all-male team, within the context of a group with poor controls and a history of losing money due to taking unchecked risk, as a risk factor.
