Having trained as a barrister, Justin took up corporate finance, working in both Africa and Singapore. He then went into marketing with a focus on corporate cash management facilities. This led him to help found Broker Services in 1986, which went on to become Barclays Stockbrokers, where he was Marketing Director. In early 2001, he co-founded Seven Investment Management, an investment management business that innovated the UK investment market with the introduction of the first Sterling Investment Wrap Account which now manages and administers in excess of £1.6 billion on behalf of professional financial wealth managers and intermediaries.

Justin has a keen interest in developing the investment market to break down as many of the traditional barriers as possible for both private investors and smaller companies. He writes regularly for national magazines and newspapers, and is a frequent commentator on television and radio, both in the UK and abroad.'
