Each fall, two weeks or so after the release of our new 40 Under 40 list, Fortune toasts the new class at a big party in San Francisco, where many of the honorees are based.

We’ve held our event at the headquarters of buzzy tech startups like Zynga and Airbnb. This year, on October 7, the bash was at GitHub headquarters, hosted by GitHub’s CEO Chris Wanstrath, who made the new list. More than half of our new 40 showed up to party—below are some shots from the event. On first mention, we’ve identified new members of the list (as well as list alums) with their full titles and companies.

Take a look, and then look back at this year’s full 40 Under 40.
