Gen Z is the most connected generation in history-yet meaningful, in-person friendships are harder to come by than ever. Despite countless digital platforms promising social engagement, many young adults still feel isolated.

Firefly Spark, an app designed by Gen Z for Gen Z, is reimagining how this generation builds friendships. Instead of relying on online interactions, the app brings people together in real life through shared activities. Whether it’s a basketball game, movie night or grabbing dinner, it makes socializing easier.
