The 35-year-old from Shropshire will be hoping to kickstart his latest challenge with the £250,000 investment on offer from Lord Alan Sugar in the new series of the BBC One show.
Chiles currently owns a consultancy business and a building materials supply company, but says he has another "strong" business plan up his sleeve.
He's spent nine years working in management.
Chiles describes himself as "self-motivated, loyal and committed" and says he loves the challenge of going up against people and winning. No surprise then he has a black belt in karate!
He says: "I consider myself one of the most credible candidates in this process. I don't believe that anyone has the wealth and breadth of business acumen that I've gained over the years."
