Dragons' Den is a reality television program format in which entrepreneurs pitch their business ideas to a panel of venture capitalists in the hope of securing investment finance from them. The program originated in 2001 in Japan, where it is known as The Tigers of Money (マネーの虎 manē no tora), a pun on "The Tiger of Malaya" (マレーの虎 marē no tora), the nickname of WWII general Tomoyuki Yamashita. The format was created and is owned by Nippon TV and is distributed by Sony Pictures Television.
Local versions of the show have been produced in nearly 30 countries, as well as one for the Arab world; in some countries, more than one version has been aired. The most popular name for the show is Dragons' Den or variations thereof, a name that originated in 2005 in the United Kingdom. The show has also been titled Shark Tank (a name that originated in the United States) and Lions' Den, and variations on those names, among others. In versions where the name of the show contains a creature's name, the investors are referred to by that name.
The contestants are usually product designers or service operators who have what they consider to be a viable and potentially very profitable business idea, but who lack funding and direction. They pitch their idea to five rich entrepreneurial businesspeople, who in most iterations of the show are referred to as "dragons", "tigers" (in the original Japanese show), "lions" or "sharks". Before the show, the contestants have named a specific amount of money that they wish to get (along with a percentage in the business that the contestant is offering to sell to the investors), and the rules stipulate that if they do not raise at least this amount from the dragons, they get nothing. In return, the contestant gives the dragons a percentage of the company's stock, which is the chief point of negotiation. The program does not show the entire pitch as scenes are selected and edited from the episode due to time constraints.
The dragons probe the idea further once the contestant has made the presentation. This will either reveal a sound business proposition that the investor may become interested in investing capital in return for equity, or an embarrassing lack of preparation on the part of the contestant (such as the contestant's lack of knowledge of the business' profits or margins), the uncovering of troubling facts (such as insufficient sales or manufacturing margins) or other reasons which may play a factor in the investors consequently rejecting the investment (such as the investor asking for a larger equity stake in the business than the contestant wants to give up, the contestant's valuation on the business being too high compared to its overall profits, the product not having any proprietary value or the investor's belief that they cannot add value to the business). A contestant may give a counteroffer to the investors, if they feel their offer is not sufficient compared to the contestant's initial offer, which may also be subject to rejection if the investor feels the contestant asking for too high a monetary amount and/or an insufficiently low equity. The deals negotiated on the program may or may not actually be carried through.
Dragons' Den series have been produced in numerous countries. Apart from Japan (where the show debuted) the show names, structures, and styles are based upon the UK version.
In Afghanistan, the show is called Fikr wa Talash (Dream and Achieve). The show's purpose is to encourage Afghans to embark on entrepreneurship. It aimed to promote entrepreneurial spirit among ordinary Afghans, with the show giving contestants a lifetime opportunity to pitch their creative business ideas before a panel of business tycoons and walk away with the cash prize of US$20,000.
The show began in 2008 on TOLO TV. The first series ended in August 2008, with the final contestant, Faizulhaq Moshkani, winning $20,000 towards his plastic recycling business. At the time of the show, he owned a plastic recycling plant in Qandahar in southern Afghanistan. After winning, Moshkani shut the factory due to the high cost of fuel to power generators. Instead, he used the $20,000 prize money to move the business to Kabul, where he planned to build a miniature hydroelectric plant to power the new recycling plant. Mariam Al Ahmadi collected the runner-up prize of $10,000. In the second season, a follow-up episode was introduced with the top contestants tracking their progress in their businesses.
The show was produced by Bamyan media with the help of the Moby Group's strategic communications arm, Lapis Ltd, and aired on the Group's most popular channel in Afghanistan, TOLO TV, reaching an estimated 7 million viewers in 2010.
Fikr wa Talash was sponsored by USAID, Roshan telecommunication (the country's leading mobile operator) and Bank e Milli (Afghan National Bank). The host is Ramiz Baktiar.[circular reference] Like the Egyptian version, it was created by Anna Elliot, founder of the NGO Bamyan Media.
In the Arab world, Dragons' Den was known as Dragons' Den: Al Aareen العرين (The Den). It was broadcast on the Lebanese channel Future Television and was hosted by Ibrahim Abu Jawdeh. The show received contestants from various Arab countries.
The panel of Dragons for the 2007 series consisted of:
- Omar El-Quqa
- Ahmad Tantash
- Nassif Karam
- Roger Azar
The Egyptian version of Dragons' Den is El Mashroua ("The Project"). The show was created in 2013 by Anna Elliot, the founder of the NGO Bamyan Media. It was broadcast on the national channel Alnahar and followed by approximately four million people. The program created the largest community of entrepreneurs[clarification needed] through a digital platform connected to the show with one million participants.
