Tom Pellereau (series 7)
Harry Potter lookalike Tom Pellerau initially kept a low profile after winning The Apprentice in 2011. But since 2012 the quirky businessman has unleashed two inventions on the world, both of which Lord Sugar invested in. The first was a product called The Stylfile Collection, which is essentially a curved "S" shape nail file. The second, out last year, was the Nipper Clipper, a safe nail-clipper for babies.
