This is such a niche market (how many investable companies are there?), I don't see how it works for most of them at all. Every deal we did at Ionic involved a very attentive and responsive partner on the other end, and our first conversation with that firm was always through a partner rather than an associate/analyst.
I suppose we're in a capital bubble and when this long tail comes back with awful returns for their LPs this issue might sort itself out.
