Back in 2005, the 14 contestants had no idea of what to expect as they were put through a series of business-based challenges in the hope of winning a job with Lord Sugar’s (or Sir Alan, as he was then called) firm.
But each series that has followed has often been more colourful than the last with more extreme characters and ridiculous challenges.
This of course, has made for some TV gold, but have you ever wondered what happened to some of the most memorable contestants once the cameras stopped rolling?
We all remember Tom and his bendy nail file and James Hill and his extremely *ahem* unforgettable grey shorts – but are they still sitting in a boardroom, or have they abandoned their business dreams completely?
In celebration of the show’s 15th anniversary, we checked in on a host of contestant to find out what they’re up to now...
Ricky Martin (Series 8, 2012)
Ricky Martin’s business skills saw him named winner of the series in 2012, going on to launch his business Hyper Recruitment Solutions alongside Lord Sugar, which is dedicated to the science and technology sectors.

The following year, the company also won a number of recruitment industry awards.
