While I admire your intentions, I think you should first look at the actual number of transgender people starting companies before drawing a conclusion that they "don't get funded". For all I know (and I don't know the numbers, I'm speculating here) we could use the same argument about Latinos and African Americans (jeez, do I hate those stupid terms).

It'd be interesting if you could backup your intentions with some numbers. I think you'll find the startup community, specially in San Francisco and the Bay Area, is specially open to all cultures and sexual orientations.

In any case, the best of lucks! :)
