The author of the @GSElevator Twitter account has been unmasked as 34-year-old former bond executive John Lefevre who has never worked at Goldman Sachs.
According to a report by The New York Times' Dealbook blog, Lefevre worked for Citigroup for seven years and that the highly popular account started as "a joke to entertain myself."
""Frankly, I'm surprised it has taken this long," said Lefevre on the phone to Dealbook.
"I knew this day would come. To pre-empt what you're about to say, legally speaking, I was never explicitly an employee of the firm."
According to the NYT story, Lefevre was offered a job as head of debt syndicate in Asia at Goldman's Hong Kong office in August 2010.
However, citing unnamed sources, Dealbook said the offer was later revoked on a non-compete agreement.
"My contract was never rescinded," said Lefevre on the same call.
"We cordially agreed to part ways to avoid a public mess. I don't know how much I can talk about it. It wasn't acrimonious."
Since joining the social network site in August 2011, @GSElevator has gathered more than 600,000 followers by tweeting conversations overheard between Goldman Sachs employees in the lifts of the company's buildings in London, Hong Kong and New York.
In January, he initially sealed a book deal with Simon & Schuster to write an exposé on Wall Street giant Goldman Sachs.
One of the 'big four' publishers aimed to release the book for October 2014 and was tentatively called Straight to Hell: True Tales of Deviance and Excess in the World of Investment Banking.
