After over 30 years of involvement with the computer and communications industries, Geoff Goodfellow enjoys being a DJ, aspiring restaurant critic, private investor, and occasional entrepreneur. He has been featured or cited in publications including the Wall Street Journal, the New York Times, Forbes, Fortune, and the South China Morning Post.

Out of a spare bedroom, in 1988 Geoff founded RadioMail Corp., the first wireless Internet-based electronic-mail connectivity and information distribution service for wireless data, cellular, and paging networks. He served as chairman and chief visionary until 1996, growing the business to offices on four continents.

Before founding RadioMail, Geoff spent 12 years with the Stanford Research Institute (now SRI International), starting part-time as a system and network "janitor" in 1974 and signing on full-time two years later when he dropped out of high school. Over the next decade he moved up the ladder to senior researcher and principal investigator specializing in computer security and networking in SRI's Computer Science Laboratory. At SRI Geoff was involved in the development of the Internet (and its predecessor the ARPANET), as well as with mobile communications, packet radio, computer security, and networking systems.

In 1996 Geoff helped start JFAX (now J2 Global Communications, NASDAQ:JCOM), the first company to provide a service that delivered faxes and voicemails to Internet email addresses from a personal telephone number. Two years later, he relocated to the Czech Republic. He is a co-owner of the Alcohol Bar in the Old Town section of Prague.

Geoff has testified twice before US Congressional subcommittees, and is co-author of The Hacker's Dictionary: A Guide to the World of Computer Wizards (1983).
