I have done a dozen or so private share sales or purchases. The model I have really come to like is EquityZen's. (https://www.equityzen.com https://www.equityzen.com) Using a crowd sourced approach, a group of accredited investors (buyers) can participate in purchasing a block of shares as a fund. A win for the smaller individual investor who could not normally participate due to various constraints (ie buying power, transaction costs). Likewise, its also a win for sellers and it applies to the Unicorn's of the world. It gives these shareholders access to a market they wouldn't normally access. It seems that selling shares privately is becoming more common, any model that connects a larger group of accredited buyers to accredited sellers is good - IMHO.
