Tim Carron-Brown, the entrepreneur behind Efdex, the electronic food and drink exchange which went into liquidation last week, has allegedly secured funds of between £70-90m to start up a new venture in the US. It was related to just-food.com that Carron-Brown has taken two former Efdex employees with him to get the new venture off the ground. If he needed their expertise, this suggests he may be attempting to set up a US-based version of Efdex.Such an operation may work more easily in the US, where Internet access is cheaper and more widespread. In the UK, Efdex encountered difficulties when it emerged that many of its potential customers did not have the necessary IT infrastructure to become members. Efdex tried to get around this by supplying clients with free computers, pushing startup costs through the roof.For more on the Efdex story,
