Hours after the deal was done, Musk fired his top executives.

Almost all of the senior leadership and half of the workforce left within two weeks.

Musk has been scheming with a small team to replace them.

"Elon has an inner circle of friends and family that he keeps close," according to the Evening Standard.

The billionaire drafts his friends into new business ventures, and some of them have already appeared on the social networking site.

Picked from Musk's inner circle of allies, friends, and ex-colleagues, these are the people who are helping him fix the social networking site.
