I'm not sure if you're including that quote because you think it contradicts what I said or reinforces it, but just in case it's the former: A portfolio company means a company that an investor has stock in, i.e. that is part of their portfolio of investments. We don't own any stock in Watsi. When we fund a for-profit startup, we trade money for stock. In Watsi's case, we simply gave them the money. A lot of people seem to have been confused about this. I feel like I've explained several times in HN threads that we have no financial interest in Watsi. We thought it was clever idea to start including nonprofits in YC, but it seems to have been such a left turn that it threw a lot of people off.
