The Tremor Video gang came to hang out.

About midway through the party, Business Insider's Editor-in-Chief Henry Blodget, President and COO Julie Hansen, and NYSE's Michael D'Agostino spoke.

Now look serious.

Kathryn Minshew of The Muse stopped by and posted with a friend.

The BarkBox trio made an appearance.

Digg's social media editor Veronica de Souza hung out with her colleague, Anna Dubenko.

Can't go wrong with such an interesting group of people.

We handed out Blowfish tablets, a hangover cure, at the end of the night.

Of course, the party wouldn't have been possible without BI's event director, Valerie Reimer (center). She's surrounded by former BIers Laura Aronsson (left), a law school student, and Katherine Churchill, now at BermanBraun.

Now, see why everyone was celebrating:
