She was the queen of the European internet scene, a founder of the First Tuesday networking club who became one of the most photographed and feted entrepreneurs of the dotcom boom.

Yet two years after the tech bubble imploded, Julie Meyer has been plunged into a battle with the very medium she did so much to promote.

A series of detailed memos purporting to be written by the entrepreneur and suggesting her latest business was in difficulty have appeared on US website fuckedcompany.com, the market leader in dotcom doom stories.

Yesterday a furious Ms Meyer categorically denied that she had written the memos. She is consulting lawyers about what action she can take.

Her business Ariadne Capital is progressing "superbly well", she said - and having attracted clients including Volkswagen, T-Mobile, BT and Royal Mail, is operating at a profit. "The emails have been fabricated; they are false, and the content is wholly untrue," she said.

Legal advisers believe the memos could have been forged by a disgruntled employee of the venture capital and consultancy firm.

In common with many firms that have appeared on fuckedcompany.com, Ariadne is likely to have difficulty getting the memos removed. The site is hosted by an internet service provider in the US over which UK law has no authority.

Ms Meyer has a reputation as one of the best networked and most driven young entrepreneurs in Europe and spent millennium night on a business trip to Israel.

She was one of four friends who set up First Tuesday, an informal monthly cocktail party for entrepreneurs which evolved into a high profile organisation for those looking to launch internet start-ups. She fell out with the other three founders when they sold it to venture capitalists in 2000.

In an interview with silicon.com last year she explained what drove her to succeed after the internet boom ended. "I knew how to seize the opportunity, and it all boiled down to one thing: I must get out there again - forget that holiday - regardless of whether the market had shifted 180 degrees, to prove my success is market-independent, recession-neutral," she said.

"I understand where the next curve is. My abilities are not tied to all boats floating on a rising tide.

"When the markets return, and the masses flood in, the real opportunities will be gone - but I will be ahead of the game. This is why my schedule these days is super-punishing. While others are vacationing in Italy, I'm scared I'm going to miss the next big thing. Call it an obsession. Why do I keep on going? As a friend of mine says, that dog hunts."
