    The mission of the St. Louis Arch Angels, started in 2005, is to provide opportunities for its members to obtain outstanding financial returns by investing in early-stage companies with high growth potential in the St. Louis region and accelerate them to market leadership. The Network was organized by the St. Louis Regional Chamber and Growth Association and the Nidus Center for Scientific Enterprise. Arch Angel members provide seed and early-stage capital in the range of $250K-$1M. Members do not invest in a pooled fund, but rather commit to invest a minimum of $50,000 a year directly in a startup in partnership with other members of the network. Members generally invest under the same terms and conditions.
