Dragon's Den has helped launch some incredible businesses in recent years - but the show has also missed out on a few opportunities.
One candidate who appeared on the hit BBC show last night has told how he's bounced back after being rejected.
Entrepreneur Mark Wong pitched his non-alcoholic beer to Sara Davies, Peter Jones, Deborah Meaden and Touker Suleyman and new Dragon Steven Bartlett.
He moved to the UK from Hong Kong as a teenager unable to speak English but went on to study philosophy at Durham University.
He was forced to give up a career as a wine expert after being diagnosed with alcohol-induced liver damage - prompting him to look at the non-alcoholic options.

He developed Imbossibrew - a beer brewed with plants to help you unwind without the alcohol and was invited to pitch it to the Dragons after winning several awards.
But none of the Dragons was interested, commenting that he was "too early into his business journey’ and ‘There was too much competition in the industry.
But since walking out of the Den empty-handed Mark has secured almost double the investment and the company has grown by 930% and won a gold award at the European Beer Challenge beating.
Mark said: "It was a great learning opportunity. I never thought I’d be on Dragon’s Den, let alone being invited to pitch - for that I’m extremely grateful.
"The comments from the Dragons were very constructive and I didn’t regret a single moment in the Den.
"We’ve only just begun the journey to change the way we drink - and I can’t wait to show them our progress in 3-5 years.”
