What they do
Series is an AI-native social network built for Gen Z. Members tell an AI friend over iMessage who they want to meet, and Series makes double opt-in introductions to the right people: friends, mentors, cofounders, and investors. No feeds, followers, or likes. Founded by Yale students Nathaneo Johnson (CEO) and Sean Hargrow (COO), who met hosting The Founder Series podcast. Since its March 2025 beta, it has passed 300,000 profiles and 500,000 messages.
