I have always thought that startups should swap some equity with other startups in order to lower the extreme risk they take on, similarly to what venture capital companies do by having portfolios.
Freelancers could also hedge risk by doing something similar.
If this is combined with, say an incubator or some social setting where freelancers help each other, risk hedging and helping your fellow freelancer would not only be nice, but profitable.
I have been looking for solutions in this space, and I have only found one, The Founders Club which is for startups where there is an equity exchange in a pool of other startups managed by VCs.
What I am asking for is other examples of equity exchange, rating systems connected to risk hedging or similar systems where risk hedging is done for startups or freelancers.
