Jeremy Elliott "Jez" San OBE (born 29 March 1966) is an English game programmer and entrepreneur who founded Argonaut Software as a teenager in the 1980s. He is best known for the 1986 Atari ST game Starglider and helping to design the Super FX chip used in Star Fox for the Super NES. Early career San received his first computer, a TRS-80, at the age of twelve in 1978 from his father, who had a career in exporting the belongings of immigrants at the time. San first became interested in video game development at a young age after playing a Multi-user dungeon (MUD) in the 1970s. Within a year he taught himself assembly language for several microprocessors. San founded Argonaut Software as a teenager in high school at JFS as a way to get software consulting jobs with large companies. He worked on security systems with British Telecom and Acorn. In 1984, he started developing his first game, Skyline Attack for the Commodore 64, and also co-wrote a book, Quantum Theory, about the Sinclair QL. He became a wizard (admin) at Essex MUD, the world's first multiplayer online role-playing game. San's late-1986 game Starglider for the Atari ST and the Commodore Amiga sold hundreds of thousands of copies (earning him £2 per copy in royalties). The money helped launch Argonaut as a larger company that started hiring other people in 1986. Argonaut growth and decline In the late 1980s, Argonaut signed a deal with Nintendo. San attracted Nintendo's attention because Argonaut was the first developer to successfully design 3D modelling on the NES and the Game Boy. X was published by Nintendo as the first 3D Game Boy game. San helped develop the first 3D graphics accelerator known as the Super FX chip that made Star Fox (released as Starwing in Europe) possible on the Super NES. In 1996, Argonaut received external funding from Apax Partners and was listed publicly on the London Stock Exchange in 2000. San's stake was reduced from 90% in 1996 to almost 50% post Argonaut Games' IPO in March 2000. San also helped found ARC International when it was spun out from Argonaut in 1998 and was its largest shareholder on IPO. San made substantial share sales during the flotation by Goldman Sachs and Warburg and in 2007 fully exited ARC. Between 1999 and 2002, San funded Codeplay and is currently the majority shareholder.
