Darren Nicholls, Product Manager for Informi said: “These former contestants have used their experience from the show to start businesses which are making healthy profits.
"Thomas, Mark, Leah and Ricky all had their profile raised significantly from winning the show, but Susan shows that if you have the right skills, such as dedication, intelligence, and leadership, you can achieve huge success, even with the setback of not winning. Of course, a solid business idea is also vital.
“Which of the contestants from this year’s series will have the right ingredients for business success? Will future growth opportunities be confined only to the business idea of this year’s winner? It’ll be fascinating to find out over the coming weeks..
