Dragons' Den: Pitches to Riches relives the most extraordinary moments from the past 13 series of Dragons' Den, fronted by self-confessed Dragons' Den obsessive Richard Osman. We discover the fortunes of some of the most unforgettable entrepreneurs after they shook hands on a deal with a Dragon.

Richard catches up with Peter Jones to see if, after his most famous investment Levi Roots, he can pull off another multi-million-pound sauce revolution. We see Deborah Meaden with one of her brightest investments - Jordan Daykin, the youngest ever entrepreneur to secure a Dragon's investment. Has he gone from pitch to rich?

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.

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.

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.

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?

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.

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.

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.

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?

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 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?

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.
