Van der Kleij was born and raised in South Africa, and moved to the United Kingdom at the age of 15. His interest in technology was sparked when his brother bought him a Sinclair ZX81 as a teenager.[1] Deciding that he lacked the technical skill to be a programmer, van der Kleij went on to study business, after which he began a career in technology by commissioning software for golf clubs to keep track of their membership. Van der Kleij became a "serial entrepreneur", creating several telecommunications companies. His first major success began with an Internet call-back business, named RealCall, which allowed advertisers to place a link in their advertisement which clients would click to receive a phone call from the advertiser. The service failed to take off, but from it, van der Kleij developed a business which alerted consumers to possible credit card fraud, which became known as Adeptra.[2][1] Adeptra expanded into the United States in 2000, which required van der Kleij to raise £30 million in funding.[1][3] After leaving the company in 2006, van der Kleij was approached by the British Government to assist in the set-up of its Global Entrepreneur Programme—an initiative to help UK-based technology companies expand and globalise their business.[4]
