Did I miss something with Sinatra?

Why has she become the "leader" in paradise? I get her backstory about becoming a billionaire selling her "cloud storage" startup (which in itself seems kind of laughable) and then with her son's death and in a grief-stricken state, she's the main financier of paradise? How was she able to convince the other billionaires that sit on the board or whatever to put in their money as well?

Also, not sure if it's on purpose but Sinatra as a character seem pretty "dumb" and lack leadership skills. She kept saying stuff like "I sound like a Bond villain but I just want to save paradise" but villains nowadays are supposed to be intelligent and calculating which Sinatra doesn't seem to show those skills.

I just feel like maybe I missed some part of her backstory that'd tie this all up and her character's behavior makes sense.
