17. The Giving Card

Founder: Dan Taylor
Founded: November 2010 (launched November 2011)

Inspired by the rise of voucher scheme businesses, Taylor had a desire to do good too. The Giving Card's memberships allow users to secure discounts on lifestyle purchases, while £10 of the £35.94 annual fee goes to a charity of the member's choice. Already the London-based start-up has secured discounts from 3,000 suppliers and partnered with 80 charities – ensuring ample choice for its 6,000 members.

Furthermore, 23-year-old Taylor (a former UK Global Student Entrepreneur of the Year) has delivered his idea with such success that he has been able to secure business angel investment and employ a team of six. We can't disclose how much The Giving Card's turning over, but take it from us, the figures are highly impressive.
