It'd be need if somebody ran a YC Hedge Fund. I'd happily pay 2% and 20% management fees! :D
Although I doubt it's that easy to buy in. Ha.
We do have a few batchmates on our platform, you can always create your own index and invest in all of them. :) (Unfortunately due to regulations we can't publicly say who they are, and viewing/investing is limited to accredited investors only... for now!)
Do it!
