David Tabizel (born January 1965) is an internet and media entrepreneur, who was the co-founder of a number of successful technology startups such as 365 Corporation (Football 365, Rugby 365 etc.),^[1] Demon Internet, Autonomy, Rage Software, Durlacher (now Panmure Gordon) and others.^[2]

He graduated from the University of East Anglia in 1986 in economics where he now sits on the advisory board ^[3] and subsequently became a behavioral economist and analyst with a specialism in the economic application of existential psychology to predict trends in industries such as technology, finance and media.

He was also involved in the forming and founding of Metrodome Film in the UK and in Ginger Media's purchase of Virgin Radio in the late 1990s. He also purchased Laughing Stock, Europe's leading comedy record label in the mid-1990s, a company whose artists included Eddie Izzard, Bill Hicks, Peter Cook & Dudley Moore, Rowan Atkinson and Arnold Brown.

Tabizel is credited with writing one of the first books on the Internet in 1991^[4] and also wrote an influential work anticipating the Internet boom of the 1990s in "The Internet an Investment Perspective" (Financial Publications Ltd 1994). Tabizel wrote an exhaustive study of the video games industry in 1993. Three of the companies co-formed by Tabizel, Durlacher, 365 Corporation and Autonomy each achieved stock market capitalizations in excess of $1 billion. Eckoh PLC a spin-off from 365 Corporation is now a London stock market quoted telecoms company.

Tabizel led the research and corporate finance efforts at Durlacher, creating a technology and media based research driven investment bank with a peak stock market value of approximately $4 billion during the peak of the dotcom boom in 2000 & is now actively involved in researching emerging trends in technology.
