As far as I remember they only mentioned in their video that they have someone in their team who worked for Goldman Sachs. Maybe they were working as senior assistants of junior intern on trial period? I worked for several largest banks, Coca Cola, Pespi and Forbes but it doesn't mean they will invest in my currency or that I have any contacts on the highest level.
Here you go, 8:10: "people who worked on Goldman Sachs" http://youtu.be/q5FDvzj8YX4?t=8m10s
It was enough for all those rumors about Goldman Sachs involvment. Some people just don't to use their heads.
