Series

Series is an AI-driven social network that operates entirely inside iMessage, letting users discover new people without installing an app. Users text a phone number (Series AI) on iMessage, explaining who they are and who they are looking to connect with. From there, Series AI messages the user back, offering what is called "shares", a carousel of 10 images of posts from other people also using Series AI looking to connect for a similar reason. Each carousel card includes a person's photo and their ask, and users can press and hold the carousel photo to start a private conversation with another user in the Series AI chat, without sharing their personal number. The pitch is aimed at founders, students, and operators who treat warm intros as the real currency of opportunity, and the launch matters because it tests whether a chat thread can replace the feed as the primary surface for professional networking. The company was built by Yale students Nathaneo Johnson and Sean Hargrow, both still seniors at the university , with Johnson serving as CEO. The two met at the Yale Entrepreneurial Society in their freshman year, hosting a podcast called "The Founder Series" where they interviewed Yale startup owners about their entrepreneurial journeys , an experience that shaped their thesis that access to networks is the hidden bottleneck behind most early-stage success. Series has drawn an unusually deep investor bench for a pre-seed, with investors including Venmo co-founder Iqram Magdon-Ismail, Pear VC, Reddit CEO Steve Huffman, and GPTZero founder Edward Tian . The company considers itself to be a next-generation social networking platform, rather than an AI app, and hails itself as one of the first to work entirely through iMessage , a positioning that puts it in direct conversation with LinkedIn and Lunchclub on distribution while sidestepping the App Store entirely.
