Dragons' Den: Where Are They Now? - Episode Guide

Umbrella vending machines on London stations was just one idea from the 100-plus entrepreneurs who entered the Dragons' Den. A year on from the first series, Evan Davis investigates if any - including designer jewellery, a glamorous glossy magazine and a board game - have been successful.

Have you ever wondered what happened to the entrepreneurs once they had suffered the dragons' maulings and the credits had rolled? The first of two programmes tracks down some of the characters who took part in series two to see how they are getting on, including poor Claire Locke and her personalised children's underwear.

What happened to entrepreneurs who faced the fire-breathers in the second series of Dragons' Den? Baby products boomed but how has the modern circus fared? Hi-tech pooper-scoopers, children's yoga and flat-pack crockery for travellers were among the other innovations.

Catching up with the stars of the previous two series - both the ones who left with the investment they wanted from the multi-millionaire investors, the Dragons, and those who walked away empty-handed. This episode features Brixton-based Levi Roots, who serenaded the Dragons and left the Den with an investment in his home-made sauce, and Peter Ensinger and David Baker who made Dragon's Den history when they convinced all five Dragons to invest in their device for saving energy.

Catching up with the champion of the fluffy toilet seat cover, the inventor of a teddy bear housing an integrated media player and the disaster-prone inventor of the water-free egg boiler.

Evan Davis revisits entrepreneurs from the previous two series, including Christian Lane who came up with a way to stop documents becoming creased.

What has happened to the two women who enraged the Dragons with their pitch for a women's construction business? And will Theo Paphitis be eating his words, after he told an entrepreneur his beach towel doubling as a surfing aid was "as useful as a pair of knickers on a kipper"?
