He came to prominence through his involvement in the purchase and sale of the famous stamps firm Stanley Gibbons which he sold at a great profit, only to see most of the proceeds lost following trading difficulties.
In 1976 Fraser became a partner in Plastic Wax, a company in Bristol which specialised in collectible records and still exists.
[1] Fraser first invested in Stanley Gibbons in 1989 when he acquired a large block of shares in the company from Clive Feigenbaum.
In the deal Fraser took shares in Flying Flowers instead of cash and he was left with an 8% stake in the enlarged company following the transaction.
On 14 March 2014 TechCrunch revealed Fraser to be the largest single investor in a $4m investment round in Coull, an online video ad tech company based in the United Kingdom.
