A startup exchange that uses blockchain

GroupVenture is a transparent OTC exchange that lets everyday people invest in startups using their smartphone or computer on a simple and intuitive interface. Like the stock market, the price per share will go up and down depending demand, in order to raise maximum funding during the round. Instead of selling actual shares of a company, GroupVenture sells "notes" When someone buys a note or share then they are buying a promissory stating if the company goes up in value the value of the note purchased will rise proportionally as well.
