Tucked away on the fourth floor right in the heart of Main Street, the hangout has proved a popular spot for executives, talent and other festival attendees.
Filmmakers and talent involved on Newness, Bitch, Lemon, Landline and Look And See staged parties at The Plexus Lodge, where the cocktails and culinary treats kept coming courtesy of chef Greg and his wife Julie.
The rooftop après-ski deck hosted a set by rapper Trap Beckham and late night karaoke for guests.
Elizabeth Olsen, Mark Hamill, Jack Black and Jason Ritter were among the guests, along with Aubrey Plaza, Jon Hamm, Elijah Wood, Melanie Lynskey, Tye Sheridan and Jacki Weaver.
Plexus is a mobile networking app in development that the company aims to launch at SXSW.
