Elon Musk said he only talked business at the party.
Chang described one party in particular, confirmed by WIRED Magazine as being hosted by venture capitalist Steve Jurvetson, cofounder of the firm DFJ, that she claimed climaxed in what is referred to in the industry as a "cuddle puddle" - a euphemism for group sex.
Jurvetson, who left Draper Fisher Jurvetson late previous year amid allegations of misconduct, hosted an afterparty for a DFJ conference at his home in Half Moon Bay, according to Axios, which cites text from the book by Bloomberg TV journalist Emily Chang.
"I don't want this to be anticlimactic, but I didn't see any sex or drugs", he wrote.
But Chang detailed that there were "several people laid down and started stroking one another.in what became a sizeable cuddle puddle".
On Wednesday, Paul Biggar, an entrepreneur who attended the party, described his experience without naming Jurvetson or DFJ titled, "That party was way worse than it sounds".
On the other hand, entrepreneur Paul Biggar said in a Medium post that he was at the party and even though he left at 12:30 a.m. before it really kicked off, he can confirm that numerous details in Chang's depiction are accurate. He wrote, "Emily Chang's article was salacious nonsense". Obviously. That DFJ party was boring and corporate, with zero sex or nudity anywhere. "She conflated what happens in [San Francisco] sex clubs in the Tenderloin, which have been around long before Silicon Valley was anything, with boring [Vice Chairman] parties on the Peninsula". DFJ partner Emily Melton expressed discomfort about the nature of the party and the firm debated whether it should pay for the shuttles to the party, according to one person familiar with the firm. "His impression was that it was a corporate party with a costume theme, not a "sex party", and there was no indication that it would become one after he left".
"If you want wild parties, you're in the wrong place".
He added: "Nothing remotely worth writing about happened".
The VC firm issued an apology, reported by Recode, in which it said: "We were dismayed to learn of behavior at the party that was completely at odds with DFJ's culture, which has been, and will continue to be, built on the values of respect and integrity. The most fun thing was Steve lighting a model rocket around midnight".
Angel investor Jason Calacanis also disputed the "sex party" characterization of the event. "I can confirm numerous details at the party. We were there for about an hour or two", he said.
