Broadridge Financial Solutions, Inc.
A financial technology company that powers the plumbing of modern investing, Broadridge processes shareholder proxy votes and investor communications for banks, brokers, and corporations, and provides software that handles trillions of dollars in daily securities trades and wealth-management platforms. It began in 1962 as the brokerage services division of payroll giant ADP, then became its own company in a 2007 spinoff, taking the name "Broadridge" as a nod to its brokerage roots. Fun fact: it helps process the votes for the vast majority of shareholder ballots cast in the U.S., quietly sitting behind many corporate elections.
