CASTELL

The Company

Dr Stephen Castell is one of the UK's leading professional consultants, and business builders, in the increasingly convergent areas of IT, telecommunications, broadcasting and the media and has for the past twenty years been Chairman of CASTELL, his own consultancy company. He specialises in the active strategising, planning, management and development of systems and businesses in information and communications technologies, broadcasting and the media, and in analysing and influencing the financial, market, economic, regulatory and legal factors which affect them. He has established a special reputation in developing businesses in voice telephony and in satellite communications, databroadcasting and strategic value-added services; and in being amongst those leading the discussion of the 'legal reliability' of information systems and technologies.

As an Expert Witness in software litigation and computer criminal prosecutions he has been involved in a wide range of cases including what is thought to be the largest civil action over a software development contract to come to trial in the English High Court. He is also a (CEDR-trained) Mediator and (ICC) Arbitrator.
