Summary
Series, an AI-native social networking platform designed for Gen Z, has closed a $5.1 million pre-seed funding round, marking a milestone for student-founded venture companies. The startup, created by Yale University seniors Nathaneo Johnson and Sean Hargrow in 2024, operates as a professional network exclusively on Apple's iMessage platform, differentiating itself in a crowded social media landscape by leveraging an existing communication infrastructure rather than building a standalone app.
The funding round closed on April 24, 2026, with backing from a notably accomplished investor syndicate including Venmo co-founder Iqram Magdon-Ismail, Reddit CEO Steve Huffman, early-stage venture firm Pear VC, and Edward Tian, founder of GPTZero. According to founder commentary, the investor group shares a unified thesis that iMessage will become the primary interface for future social and professional networking. This represents the largest venture capital raise by Ivy League student founders to date.
Series demonstrates substantial early-stage metrics that validate founder positioning. The platform has attracted more than 750 active campuses, with 83% user retention among active users—a figure Johnson highlighted as exceeding Facebook's retention rates during its early growth phase. Weekly engagement data from 2025 showed over 20,000 messages sent and received within a seven-day period, indicating consistent usage patterns among its target demographic.
Notably, Johnson disclosed that the founders received multiple acquisition offers during their fundraising process, including a $500,000 offer within two days of announcing the initial $3.1 million pre-seed and a subsequent $8 million offer. The team declined both proposals to maintain strategic control and ensure investor alignment around their core vision. This disciplined capital raising approach underscores founder conviction in their market thesis and long-term strategy.
Following the pre-seed close, Series has officially launched its seed funding round, positioning the startup for capital deployment as it expands user acquisition and platform capabilities across its Gen Z target market.
