There are at least 2 trans billionaires, Martine Rothblatt & Jennifer Pritzker.
Quoting a Ben Goertzel email to Epstein:
"Martine Rothblatt She's CEO of $2 billion pharma firm United Therapeutics. Formerly Martin Rothblatt. Made her/his $$ initially in satellite radio.
She's a biz-person not a scientist, but very insightful and visionary.
I know her slightly better than I know you, I guess. She's never invested/donated in my projects, but we have a lot of mutual liking and respect, and she may well do so when the time is right. She has invested in David Hanson's robotics company, and some of Ray's projects. She is a strange, but highly effective, mix of hippie, lawyer and hard-nosed business-person.... She kept the same wife, Bina after her sex change. David Hanson's Bina48 robot head looks like Martine's wife Bina, and is pretty cool...."
Can't find any direct mention of Jennifer Pritzker so far, but his cousin Tom Pritzker seemed pretty close to Epstein, I came across an email where Tom is asking about "Veronika", in context that suggests this is a girl provided by Epstein. Sorry I don't have time to keep digging.
