FOUR men from a Dunmow company have scooped the biggest ever cash investment ever on BBC Two show Dragons' Den.

On the show, which aired on Monday night (August 4), he had the Dragons fighting over the investment with the eventual winners Deborah Meadham and Theo Paphitis investing one quarter of a million pounds in exchange for a 25 per cent stake of the company.
