That's the whole point, you invest in people once they've had significant traction. I think Dustin Moskovitz is a strong candidate, along with Brian Armstrong and as mentioned earlier Max Levchin and Jack Dorsey. PG's YC and Peter Thiel's Founders Fund are only accessible to HNWIs. If you can get your hands on secondary shares, Patrick Collison, Parker Conrad and Ryan Peterson would be at the top of my list. Last but not least, I bet that Mikhail Kokorich will go public again, despite all the turbulence.
