Yale Students Raise $5.1M Pre-Seed to Build Series: The AI-Powered Social Network Transforming Gen Z Networking

The startup ecosystem in 2026 continues to prove that innovation has no age limit. Two Yale University seniors, Nathaneo Johnson and Sean Hargrow, have successfully raised an impressive $5.1 million pre-seed funding round for their groundbreaking AI-powered social networking platform, Series. Designed to function entirely through iMessage, Series is redefining how Gen Z and young professionals connect for business, networking, friendships, and even dating.

What Is Series?

Series is not just another social media app. It is an AI-first social networking platform built around conversation-based interactions. Instead of downloading a separate app, users simply text Series AI via iMessage, describe themselves, and explain who they want to connect with.

Using artificial intelligence, Series curates personalized introductions by sending users “shares” a carousel of profiles from people with similar goals. Whether someone is seeking startup collaborators, professional mentors, investors, or personal connections, Series uses AI to create warm introductions efficiently.

This conversational interface reflects the growing shift in technology from traditional user interfaces to AI-driven interaction models, similar to the transformation from Google Search to ChatGPT.

The Vision Behind the Startup

Johnson, who studies computer science and economics, and Hargrow, a neuroscience student, began their entrepreneurial journey during their freshman year at Yale. Their early experiences interviewing founders and CEOs through the Yale Entrepreneurial Society inspired them to focus on one major insight: the power of warm connections.

By leveraging AI, they sought to solve one of the biggest challenges in networking finding the right people faster and more effectively.

After multiple product iterations, the founders refined their concept and officially launched Series, quickly gaining traction across over 750 college campuses.

Why Investors Are Betting Big on AI-First Young Founders

Series’ $5.1 million pre-seed round attracted notable investors including:

• Venmo co-founder Iqram Magdon-Ismail
• Pear VC
• Reddit CEO Steve Huffman
• GPTZero founder Edward Tian

This reflects a broader startup trend where AI-native young entrepreneurs are gaining investor confidence due to their deep understanding of emerging technologies and consumer behavior.

Investors increasingly believe founders who build AI-first companies from inception have a competitive advantage over traditional companies trying to adapt later.

Rapid Growth and Impressive User Metrics

Series has already demonstrated remarkable engagement:

• Active across 750+ campuses
• 82% Day-30 user retention rate
• Expanding beyond college students to professionals
• Growing popularity for business networking, friendships, and dating

These numbers suggest that Series could become a serious competitor in the future of AI-powered social platforms.

Building the Future of Social Networking

Rather than relocating to Silicon Valley, the founders have chosen to build from New York, aligning with the rise of “Silicon Alley” as a major startup hub.

Their fresh capital will primarily be used to:

• Hire additional engineers
• Expand AI capabilities
• Improve user experience
• Scale nationwide and beyond

Lessons for Aspiring Startup Founders

The success of Series offers valuable insights:

1. Start Early

Johnson and Hargrow prove that entrepreneurship can begin during college.

2. Solve Real Problems

Their platform addresses genuine networking inefficiencies.

3. Leverage Emerging Technology

AI remains one of the strongest startup growth drivers in 2026.

4. Build with Speed

Final Thoughts

Series represents the future intersection of AI, social networking, and startup innovation. As conversational AI continues reshaping industries, startups like Series demonstrate how younger founders are building entirely new categories instead of simply improving existing platforms.

For aspiring entrepreneurs, this story reinforces that bold ideas, strategic execution, and effective use of AI can create extraordinary startup opportunities even before graduation.
