Entrepreneurs Shaf Rasul and Julie Meyer will give wannabe businessmen and women the chance to secure £50,000 in funding, if they manage to convince the duo that their business idea has potential.
The new version of the show and will be updated weekly. Stepping into the shoes of Evan Davis (the host of the BBC Two version) will be Dominic Byrne, the newsreader from Radio 1's Chris Moyles Show.
In keeping with the show's new online format, the new dragons have backgrounds in business technology.
Meyer is known in the business world for supporting internet and technology entrepreneurs and founded dotcom brand First Tuesday in 1998, a matchmaking service that brought together people to network on the first Tuesday of every month. She subsequently sold the business and has since helped brands including Skype and Lastminute.com.
Rasul founded optical media distribution company E-Net Computers in 2000. It is now the largest storage media distributor in Europe. He has also developed a venture capital investment portfolio worth about £30m.
Meyer said: "The opportunity to align with Dragon's Den interested me as continuing to peel back the onion for the mass market in terms of what it takes to build businesses is one which I couldn't pass up."
Meyer and Rasul will have to live up to the melodramatically tough personas typically adopted by BBC Two dragons -- Deborah Meaden, Duncan Bannatyne, Peter Jones, Theo Paphitis and James Caan.
Despite their fearsome demeanours, the dragons are not infallible and their judgement is sometimes clouded by their arrogance. Brand Republic's appeared on the BBC show with his brother, in an attempt to get investment for their board-game, 'About Time'.
The Gill siblings were sent packing but their game has since been proving its worth -- they have clinched deals with retailers including John Lewis and Hamley's, as well as signing a distribution agreement with US retailing giant Barnes & Noble.
