Yale Students Secure $5.1M to Launch AI-Powered Social Network via iMessage
In a significant development within the tech startup ecosystem, Yale University seniors Nathaneo Johnson and Sean Hargrow have successfully raised $5.1 million in pre-seed funding for their innovative social networking platform, Series. This funding round attracted prominent investors, including Venmo co-founder Iqram Magdon-Ismail, Pear VC, Reddit CEO Steve Huffman, and GPTZero founder Edward Tian.
Series distinguishes itself as a next-generation social networking platform that operates entirely through Apple’s iMessage, offering a seamless and integrated user experience. Unlike traditional AI applications, Series leverages artificial intelligence to facilitate meaningful connections among users directly within their existing messaging environment.
Innovative User Experience
The platform’s functionality is straightforward yet impactful. Users initiate interaction by sending a message to Series AI via iMessage, detailing their identity and the type of connections they seek. In response, Series AI presents a share—a carousel of ten images showcasing posts from other users with similar interests or objectives. Each carousel card features a user’s photo and their specific request or interest. Users can engage further by pressing and holding a carousel photo to start a private conversation within the Series AI chat, all without disclosing their personal phone numbers.
Founders’ Journey and Vision
Johnson, pursuing studies in computer science and economics, and Hargrow, a neuroscience major, embarked on their entrepreneurial journey during their freshman year at Yale. Their collaboration began with a podcast under the Yale Entrepreneurial Society, where they interviewed various founders and CEOs to glean insights into building successful businesses. These experiences underscored the significance of warm, personal connections in professional networking.
Motivated by this realization, the duo spent their freshman summer developing a business centered on using AI to facilitate warm connections. After multiple iterations and nearly a year of prototyping, they finalized the concept for Series and commenced fundraising in March 2025. Their efforts culminated in assembling a dedicated team of eight individuals committed to bringing their vision to fruition.
Strategic Positioning in the AI Landscape
The launch of Series coincides with a transformative period in technology, characterized by rapid advancements in artificial intelligence and a shift from traditional user interfaces to conversational interfaces. Johnson observes this evolution as a transition from conventional search methods, like Google, to interactive AI-driven platforms such as ChatGPT. This paradigm shift emphasizes the efficiency and immediacy of conversational interactions over traditional browsing and clicking through web pages.
By integrating AI within the familiar environment of iMessage, Series aims to capitalize on this trend, offering users a more intuitive and engaging way to connect with others. This approach not only enhances user experience but also positions Series as a pioneer in the convergence of social networking and AI-driven communication.
Market Reception and Growth Metrics
Since its inception, Series has expanded its reach beyond its initial college-student user base, now targeting both Generation Z and professional audiences. The platform has been adopted by students across more than 750 campuses, demonstrating its widespread appeal and versatility.
User engagement metrics are particularly impressive. Activated users on Series exhibit an 82% retention rate through Day 30, surpassing early benchmarks set by platforms like Facebook. While the primary use case for Series has been professional networking, the platform has also seen adoption for dating and friendship-building purposes, indicating its adaptability to various social needs.
Competitive Landscape
Series enters a competitive market with other AI-driven networking platforms, such as Boardy AI, which also utilizes artificial intelligence to facilitate network introductions. However, Series’s unique integration with iMessage and its focus on creating warm, personal connections set it apart from its competitors.
Future Plans and Expansion
With the fresh infusion of capital, Series plans to expand its engineering team and enhance product capabilities to meet growing user demand. Post-graduation, the company intends to maintain its operations on the East Coast, leveraging its established network among Ivy League institutions and other prominent schools in the region.
The decision to remain on the East Coast aligns with a broader trend of young consumer-focused founders choosing New York over Silicon Valley. Johnson emphasizes the strategic advantages of this choice, citing the strong belief in the potential of Silicon Alley and the existing network Series has built in the area.
Balancing Academia and Entrepreneurship
Notably, both Johnson and Hargrow have chosen to complete their degrees while simultaneously managing their burgeoning startup. This decision reflects their commitment to both their academic pursuits and entrepreneurial ambitions. Johnson acknowledges the challenges of balancing coursework with the demands of running a company but views it as an opportunity to maximize the use of their time.
He encourages others to utilize their available time to pursue their true passions, noting that many people are hesitant to make full use of their extra time. This perspective underscores the founders’ dedication and proactive approach to achieving their goals.
Conclusion
The successful funding and launch of Series highlight the potential of integrating artificial intelligence with existing communication platforms to create innovative social networking experiences. By leveraging the ubiquity of iMessage and focusing on facilitating warm, personal connections, Series is well-positioned to make a significant impact in the evolving landscape of social media and professional networking.
