Thomas Peterffy is the Chairman and Chief Executive Officer of Interactive Brokers Group, Inc. a global electronic brokerage firm with approximate market cap of $11 billion. Mr. Peterffy has been at the forefront of applying computer technology to automate trading and brokerage functions since he emigrated from Hungary to the United States in 1965. 

Prior to forming Interactive Brokers, Mr. Peterffy studied civil engineering in Hungary. In December 1965, at the age of 21, he immigrated to the United States. From 1966 to 1967 he worked as a draftsman for Madigan-Hyland and, from 1967 to 1968 as a computer programmer for Aranyi Associates. In 1969, he joined Mocatta Metals as a computer programmer and later became Director of Research and Trading.

In 1977 Mr. Peterffy became an individual floor-trader at the American Stock Exchange, after purchasing a seat and trading as an individual marker maker in equity options. Mr. Peterffy is among the first to apply a computerized mathematical model to continuously value equity option prices. Five years later, Mr. Peterffy builds and runs an automated trading system for equity options and a year later, in 1983, he may be the first to develop a tablet computer for use by his employees trading on exchange floors. By 1986 Mr. Peterffy develops and employs a fully integrated, automated market making system for stocks, options and futures. As this pioneered system extends around the globe, online brokerage functions are added and, in 1993, Interactive Brokers is formed.

Today Interactive Brokers is the largest electronic broker as measured by DARTs, providing direct access trade execution and clearing services to institutional and professional traders for a wide variety of electronically traded products including stocks, options, futures, forex, bonds, CFDs and funds on over 100 trading venues around the world.
