A Spectacle of a Grand Opening Party for Cosm Atlanta

A Spectacle of a Grand Opening Party for Cosm Atlanta

When renowned venue Cosm got ready to launch in Atlanta, our team designed a grand opening spectacle that brought movie premiere excitement from the first step to the last. Because the event had to marry Cosm’s Los Angeles roots with our Atlanta audience, from arrival to ribbon cutting, across three interior levels, we made sure guests enjoyed an experience on par with the scale and innovation of the space.

This was much more than a party in a beautiful building, but we had just eight weeks to put it together. In fact, our site checks happened before construction was complete, so we conceptualized the entire experience from blueprints and renderings for a building that didn’t fully exist yet. During our site visits, we tracked the building as it evolved, then loaded in wearing PPE in an active construction zone while the venue’s team trained servers around us. Last-minute changes kept coming, and we absorbed each one without losing the vision.

Here’s how it all came together for one spectacular opening that kept the (after, after) party going until three in the morning!

The arrival: A black carpet premiere

Instead of a standard entrance, we staged a full movie-premiere experience. Exterior searchlights swept the sky above Centennial Yards, announcing to the neighborhood that something major was happening. A custom-cut black carpet led guests to the door, and two groups from the Atlanta Drum Academy stood on either side, facing off in a live drum battle as guests walked the carpet where they were greeted by ATL Hawks Dancers, Harry the Hawk, and Freddie Falcon.

Before attendees even saw the inside of the venue, they felt its energy, and this bold production honored Cosm’s West Coast entertainment identity.

The reveal: A dome that came alive

Inside, we built the night around the venue’s signature feature. During the early hours of the party, the enormous dome overhead stayed dark. At the ribbon cutting, it burst to life. That was the moment the whole night was built toward, and holding it back made the effect much bigger.

Once the dome was live, Cosm showed the 2026 NBA Finals game between the New York Knicks and the San Antonio Spurs across it, allowing guests to experience the venue’s true purpose.

Below the dome, we ensured the décor was just as eye-catching. Black and white with pops of red set the tone through florals,  highboys, lounge groupings, branded pillows, and alternating black and white drapery panels. A 360-degree photo booth and a branded ice sculpture displaying champagne glasses gave guests something to do and share.

The afterglow: A second act upstairs

When the formal program ended, the crowd moved upstairs for an after party with moving lights and sets by DJ Chika Takai, keeping the energy going and giving guests a different atmosphere to settle into.

We elevated the existing booths and cocktail tables with florals, votives, uplights, and a floral statement piece wrapped in LED rope. Cosm 6-ft. LED marquee letters, flanked by peach trees as a nod to Atlanta, anchored a stage with black skirting and a circular DJ booth. Bar florals and red accents continued the palette, while décor across the outdoor deck made existing furniture feel custom. A skirted stage, custom-printed spandex truss structures, and a branded LED DJ booth completed the perimeter.

The lasting impression: An influential guest list

This event created the first impression of a soon-to-be Atlanta landmark, and it built lasting momentum for the venue. It introduced Cosm to 1,000+ of the city’s most influential people with a guest list that read like a cross-section of Atlanta’s cultural and sports icons, as well as Atlanta’s leading lifestyle, food, and sports content creators, in addition to Cosm execs and Atlanta political and business figures. As an indication of the event’s success — the night was planned to end at midnight, but most people stayed and celebrated until 3 a.m.

The result of our strategic planning and flawless execution was a launch that felt effortless to the guests and worthy of the landmark it celebrated. Every detail served the purpose of the night, introducing Atlanta’s newest destination to the people who will have an important role to play in its success.
