"Cindy is a transplant from Seattle, where she was previously a Research Scientist and Engineer @UW Bioengineering." --Seems to qualify.
"Kelly was previously at Google as a UX design intern for YouTube and is currently Senior at Carnegie Mellon University double majoring in Human Computer Interaction and Industrial Design." --Borderline. I'm not sure whether UX design includes handling code or not; if so, it would definitely qualify; if not, it could be dismissed.
"Prior to Goldbely Vanessa headed up UX and Visual Design at Blip.tv, and was a Senior Interactive Designer for Gilt Groupe. [...] Vanessa handles UI/UX and all things creative at Goldbely." --Again, if "UI/UX" includes handling code, that would seem to qualify; if not, maybe not.
So it looks like 1 to 3, assuming you mean what I think you mean.
[Edit: not originally included was this: "Iolanthe received her Masters of Engineering, EECS in 2010 from MIT and also holds a B.S., EECS, Physics from MIT." This brings the count up to 2-4 out of 10.]
So %50 are technical of the ones who are known.
Two more are still in stealth mode.

Ummm
> Iolanthe received her Masters of Engineering, EECS in 2010 from MIT and also holds a B.S., EECS, Physics from MIT.
