Dragons' Den: Where are the previous winners of the BBC One show now?

Dragons' Den returns for its 21st series at 8pm tonight on BBC One after filming the show last year.

Regulars Sara Davies, Touker Suleyman, Peter Jones, Deborah Meaden and Steven Bartlett are going to be joined by guest investors such as former Manchester United star Gary Neville for the first time in this edition of the show.

The series debut will show the first batch of budding entrepreneurs vying for an investment from the famous business moguls.

They would do well to learn a thing or two from some of their most successful predecessors, such as Levi Roots and Scott Cupit - and their brands Reggae Reggae Sauce and Swing Patrol respectively.

Take a trip down memory lane and revisit some of the show's other biggest winners below.

Levi Roots - Reggae Reggae Sauce

Series 4's debut episode in 2007 featured charismatic Reggae singer and chef Levi Roots, who presented his spicy Reggae Reggae Sauce - concocted from a secret recipe from his grandmother - to the Dragons. 

While Duncan Bannatyne showed no faith in the opportunity, Peter and former co-star Richard Farleigh took the plunge and invested £50,000 for a 40 per cent stake in the business, and their investment ended up being extremely well-judged.  

The brand now appears on shelves in all major UK supermarkets, with the 2023 Sunday Times Rich List estimating that Levi's worth - and that of his company with it - is now approximately £30 million.

That puts a 40 per cent share in the company at £12m, with the deal held up as one of, if not the most successful business ever seen on the show.

Neil and Laura Westwood - Magic Whiteboard

Founded in 2006 by husband and wife duo Neil and Laura Westwood, the Magic Whiteboard is an A1 roll which will stick to anything thanks to static.

Two years into their enterprise, the couple entered the Den, and received offers from a remarkable four Dragons - crucially including Theo Paphitis, owner of stationary chain Ryman.

He and Deborah together invested £100,000 for a 40 per cent equity in the firm, but had their shares bought back by the Westwoods in 2014 at eight times what they got them for - valuing the business at £2m.

The growth did not stop there, with the following years seeing Magic Whiteboards stocked and shipped internationally, while the brand branched out into more diverse products such as magnetic table top whiteboards and tree-free notebooks.

Louise Ferguson and Kate Cotton - Skinny Tan

Louise Ferguson and Kate Cotton pitched their product Skinny Tan alongside three tanned dancers in bikinis demonstrating the product's results.

The 'skinny' in the name refers to its trimmed down ingredients list which leaves it more naturally-derived and cruelty-free. 

Louise and Kate were after £60,000 for a 10 per cent stake in their self-tanning product business, which claimed to also eradicate cellulite, in 2013 - by which point it had already turned profits of £600,000.

Kelly Hoppen and Piers Linney obliged and by 2014, reports showed they had made £1m in revenue.

The company was sold in 2015 for an undisclosed sum but the Dragons and co-founders remained shareholders.

In 2017, Louise told The Sun that their turnover was 'several million pounds a year' and it has been reported since that the founding duo have made over £5m.

Asi Sharabi, David Cadji-Newby, Tal Oron and Pedro Serapicos - Wonderbly  

Wonderbly was a personalised children's book business pitched by fathers Asi Sharabi, David Cadji-Newby, Tal Oron and Pedro Serapicos in 2014.

With revenue in excess of £30m, and more than two million units sold worldwide, Wonderbly is comfortably among the most successful Dragons' Den entries.

They received a £100,000 investment from Piers Linney for just four per cent of the business, indicative of the success it was predicted to become.

Former Dragon Piers said the year after the products appearance on the show that it was already on track to be 'the most successful business to have ever passed through the Den's Walls'.

Since the show, Wonderbly has sold over 8 million books worldwide in multiple languages, and has even been nominated for a BAFTA.

Scott Cupit - Swing Patrol

Swing patrol is a dance school launched in 2009 by Scott, but it hit the big time in 2014 when he pitched it on Dragon's Den's 12th series.

He walked away with a £65,000 investment from Deborah and now boasts a community of over 12,000 dancers and troupes which perform across the country.

Their headline-making did not end when Scott left the Den.

In 2015, Swing Patrol broke the Guinness World Record for the largest Charleston dance - with 975 people participating.

They also performed for David Cameron while he was Prime Minister.

The group now has the role of 'dancers in residence' at the Bishopsgate Institute, where they hold many social events and workshops. 

Peter Moule - Chocbox

Entrepreneur Peter Moule saw his product enjoy one of the fastest successes in Dragons Den history after he appeared on the show in 2007.

Chocbox, with a slightly misleading name, is a small plastic container designed to safely hold electric wires.

Duncan joined forces with another former Dragon - James Caan - to invest £150,000 for a 36 per cent stake in the business.

Three months later, Mr Moule signed a three-year deal with electronics distributor GET PLC for £25m, making him a millionaire.

The £1 gadget was expected to sell five million units per year in 152 countries during the deal.

The product still ships to 152 countries, but now with a whopping annual sales target of 100 million units, according to the Evening Standard.
