I love this sort of creativity. There’s a blockchain startup that might just simulate this in its ecosystem: drop deck. Check out their flowchart and white paper for more (I’m not affiliated with them. I just like their concept).

Speaking of blockchain, I wonder if there’s some way to weight the edges of these graphs based on prior success. So when allowing entrepreneurs to pick 3 investments, we record their success rate so that we can tweak which entrepreneurs make for good referral nodes in the friendship graph.
