AI social network that runs entirely inside iMessage
Series is a social network that operates entirely through iMessage: users text Series AI describing who they are and who they want to meet, and receive a carousel of matching members — connecting without exchanging personal numbers. Founded in 2025 by Yale seniors Nathaneo Johnson and Sean Hargrow. No valuation has been disclosed. NOTE: distinct from Series (the fintech) and from any similarly named company; this is series.so, the iMessage social network.
