Ogden, 55, has been in the IT industry since 1985. He was managing director of WorldPay, a Jersey-based internet payment company, when it was sold to the Royal Bank of Scotland in 2002 for £40m. His stake was not disclosed at the time but was likely to have been worth at least £10m.
He is now running the Voice Commerce Group in Cambridgeshire, which is developing security for financial transactions that use voice recognition. We value Ogden at £35m for now but he should go much higher.
