A marketplace for pop-up micro-venues that appear only during specific shadow hours when sunlight angles create optimal privacy and ambiance.
You scan a building at 6:47pm and see nothing—then at 7:02pm, your phone reveals a glowing blue outline where a hidden platform descends from the rooftop, music floats up from the alley below, and you realize 30 people are gathered in a space that didn't exist 15 minutes ago and won't exist after 8:15pm when the shadows shift.
Property owners list their underutilized spaces—rooftops, alleys, walls—with available shadow hours.
Hosts browse and book venues for 2-3 hour twilight windows, transforming them into intimate experiences.
During shadow hours, venues activate. Before and after, they disappear—leaving no trace.
