Dragons' Den - Season 13

In the series opener, an online property businessman feels the wrath of the Dragons and a yoga instructor tries to bring some much- needed zen into the Den. But will any of the entrepreneurs manage to secure some of the Dragons' cash?

A former city accountant enters the den with an entourage of dancers as she tries to win over the Dragons with her Nigerian-inspired snacks, a businessman from Sheffield pitches a lid for a cement mixer and new Dragon Nick Jenkins impresses everyone when he showcases his portfolio of languages and accents.

A duo use their cheeky charm to try to convince the Dragons to invest in their solution to tidying TV cables, the male Dragons try out some muscle-enhancing clothing, and the Den is the last hope for a couple who have worked for 25 years on their diving safety device.

It's crunch time when a businessman from Liverpool enters the Den with his crisp business, the gloves are off when an entrepreneur clashes with the Dragons and an ecologist turns the Den into a public convenience to demonstrate his germ-fighting gadget.

A technology entrepreneur brings a sports car into the Den to demonstrate his vehicle security app, a pair of hoteliers are looking to expand their business empire with a gluten-free food range and a duo are looking for investment in their luxury chocolate company.

A husband-and-wife team from Liverpool take the Dragons on a tour of the Den in their electric tuk tuk, a married couple come in with their Korean-inspired sauces, and the pressure of the Den proves all too much for a young entrepreneur from Manchester. But will anyone manage to walk away with some Dragon capital?

The razor sharp Dragons quiz an Anglo-French duo about their hair-raising business venture, a mum of two attempts to get the Dragons to bite on a deal in her vegetables in disguise and a mad scientist gets the business moguls to make some slime but will he convince them that he has a business experiment worth backing?

A former banker tries to convince the Dragons to invest a whopping £2 million in his idea to renovate an old London Underground station; a cyclist rides into the Den with hopes of an investment in his cycling tours business; and a farmer comes in looking for £50,000 for 10 per cent of her alcoholic mixers venture, but will she walk out of the Den toasting success?

In the finale of part one of the series, the Dragons go back to school with a post term storage business for public schools, an engineer is looking for investment in his invention to assist dog and horse owners, and will a duo's flat pack furniture get the Dragons seal of approval or will it fall flat?

It's the last chance for hopeful entrepreneurs to leave with some Dragon capital before the lift doors close.

The Dragons turn fifty shades of angry over a product that promises to banish grey hairs, and they get more than they bargained for when a zombie bootcamp business turns the Den into a little shop of horrors.

An entrepreneur returns to face the Dragons for a second time with a product that helps you exercise at your desk, and a former figure skater from Russia ends up skating on thin ice with Peter Jones over her company valuation.

Why did the chicken cross the road? In this episode, the humble hard-boiled egg is turned into an investment proposition. But will the Dragons want to shell out? And an innovative camping stove sparks the interest of the multimillionaire investors, but can any of them secure a deal?

This episode's pitches include a portable drum kit that doesn't need drums. But will the innovative entrepreneurs be willing to dance to the Dragons' tune? And the Den is left a little deflated over a nervous pitch for an inflatable tanning tent.

A trailer tent tall enough for Peter Jones to stand up in has the Dragons reaching for the instruction manual, and an entrepreneur with a self-serve beer pump hopes he won't be leaving the Den bitter.

The final episode of the series includes ice cream that claims to be healthier than an apple and headphones that don't cover your ears, and a former barrister gets a lesson in margins from Touker Suleyman.
