A lavish party meant to celebrate the 30th anniversary of New York City’s “Silicon Alley” tech scene turned into a bust — after a building permit snafu left hundreds of attendees stranded in a “freezing” building lobby, The Post has learned.
Roughly 1,300 people were set to attend the $95-a-head event, “30+ Years of Silicon Alley,” on the 41st floor of 180 Maiden Lane in the Financial District.
The Friday shindig was billed as a “one-night-only celebration” of “three decades of tech & innovation in New York,” with jazz and cocktails followed by a live performance by DJ Isaac Ferry.
However, an occupancy certificate for the sky-high Maiden Lane party space listed a maximum of just 186 people at a time, according to public records reviewed by The Post.
What’s more, the certificate was classified as temporary and expired on July 23, 2023.
While some executives made it upstairs, hundreds of other well-dressed guests — including some whose firms had cosponsored the shindig — were stranded in the frigid lobby.
The local fire marshal told guests that the party space was way above its max occupancy and had to shut down, sources said.
“There was a huge queue snaking around the lobby, which led to escalators and then elevators up to the event. Hundreds of people, and the line did not move at all,” one attendee told The Post. “It was an indoor lobby, of course, but huge and airy, and freezing.”
Event organizers had submitted a “temporary place of assembly” request for the 41st floor on Jan. 29 — just one day before the Silicon Alley party was scheduled to take place, city records show. But city officials raised “objections” to the filing, which appears to have never received final approval before the party.
The records don’t specify what the objections were.
The event’s steering committee included New York tech heavyweights like Julie Samuels of the influential trade group TechNYC and Kevin Ryan of AlleyCorp.
Major sponsors included giants like Amazon, Microsoft and Sequoia, as well as an army of local VCs and tech startups.
“Everyone was outside and wouldn’t be let up,” a second source added. “The lobby was not warm. It was a very bad situation.”
Stranded guests were left with no choice but to leave. Some headed to local hotspot Old Mates and other nearby bars, sources said. Later in the night, security began letting some guests into the party venue, but on a “one-in, one-out” basis, one of the sources said.
“Silicon Valley is famously lame at partying, so at least we’ve begun to compete with them on that front,” one dejected partygoer told The Post.
Others voiced their frustration on social media, with one writing on X that the party had “turned into “Fyre Festival” – a reference to the infamous doomed music festival.
Representatives for the steering committee declined to comment.
By Saturday, the event’s organizers had sent an email apologizing for the mess and promising refunds to ticketholders.
“Due to a permitting issue with the venue that was outside of our control, we were unexpected told that we couldn’t admit any additional guests at a certain point in the evening, and that the celebration ultimately needed to be cut short,” the organizers said in an email, which was obtained by The Post.
180 Maiden Lane was acquired by real estate firm 99c in 2024.
The skyscraper’s events are managed by the hospitality group Happier People Management, which is listed as a “production partner” for the event, and the affiliated Water Street Associates, a self-styled “creative hub” that oversees venue at 180 Maiden Lane and nearby 161 Water Street.
Happier, WSA and the FDNY did not return The Post’s requests for comment.
