The Business Plan

How To Win In The Den casts an analytical eye over the highs and lows experienced by the hundreds of brave entrepreneurs who have dared to enter the Den over the last nine series. We'll be breaking down the key ingredients that lead to a successful outcome and explore the tough lessons that have been learnt at the hands of the Dragons. This week they share their expertise on how to create a successful business plan - six vital lessons for any up-and-coming entrepreneur.

Chris Barnardo and Richard Blakesley entered the Den in 2010 with a magical product and a solid business plan. They shook hands with Duncan Bannatyne, but a year on, have they conjured up the impressive sales figures they expected? Liz and Alan Colleran stood before the Dragons this year with their innovative caravan sleeping bag. New Dragon Hilary Devey invested in the couple in spite of their shaky financial knowledge. Find out how the deal is coming along. Deborah Meaden and Theo Paphitis both thought Patrick van der Vorst's timing was right on the money when he entered the Den last year with his online antique valuation website. But when one half of his Dragon duo pays him a visit, will they still think the time was right to invest? And after nine series of the Den, find out which entrepreneur's business plan was good enough to deliver a masterclass.
