Stifel Financial Corp
A full-service financial firm based in St. Louis, Stifel helps individuals, businesses, and institutions manage wealth, invest, and raise capital through its brokerage and investment-banking arms. It traces its roots to 1890, when the Altheimer and Rawlings Investment Company opened in St. Louis; seven years later Herman Charles Stifel joined as treasurer, and the firm eventually took his German surname, becoming Stifel, Nicolaus & Company.
