Picture American sports fans trading their read on every game in real time, with the crowd setting the price, and ProphetX running the exchange where it happens. The Hoboken sports prediction exchange's $35M round beats 68% of rounds at its stage in the last six months, backed by MaC Venture Capital and Sharp Alpha. With 7 open roles, 4 in engineering, and $64M raised over six rounds, early engineers would shape the product.
