10. Hilary Devey – Founder, Pall-EX
When her father declared bankruptcy, their family lost nearly everything. Devey had drop out of school at the age of 16 to help support her family. Hilary gave up her social life and focused on making the most with what she had. It was this hard work that led to her success with Pall-EX, and eventually to her very own spot on BBC’s Dragons’ Den.
