How a Yale student raised $3.1M in 14 days for an AI social network

Executive overview

Most social networks compete on follower counts and engagement metrics. Series takes a different approach: AI agents make warm introductions over iMessage, removing the numbers entirely.

Nathaneo Johnson, 21, built and launched Series while studying at Yale, raising $3.1M in 14 days — the largest round raised by any current Ivy League student.

Warm network access is the real barrier to opportunity; agentic matchmaking can democratise it.

The problem Series solves

• Getting the right job or investment depends heavily on who you know, not just your qualifications
• A college student without a "dad's golf buddy" connection loses to an equal candidate who has one
• Existing social platforms are built around follower counts — Series strips those out entirely
• The product is agent-to-agent: no public numbers, no vanity metrics

How the product started

• Johnson and his co-founder ran a podcast interviewing founders from 23andMe, Genius Lyrics, and Runway
• Early experiments: a chatbot that used email to make warm intros, blasted to Yale and Princeton mailing lists
• It spread rapidly for startup ideas, art projects, and professional introductions
• That traction confirmed the core thesis: AI-brokered warm intros should be the future of networking

Fundraising the $3.1M round

• Early VC feedback was skeptical — the idea didn't fit the hot B2B trend of early 2025
• A trip to San Francisco for a second pitch turned into what Johnson calls "a million dollar dinner"
• The pitch frame that worked: "We're not competing in an existing market — we're creating a new one"
• The narrative: consumer AI is shifting, there's a technology window, and no one has done this in social yet
• Speed was intentional — moving fast even when things break is a strategic choice, not recklessness

Going viral with the intern house

• Instead of remote, paid interns doing UGC work online, Series moved interns into a shared house
• The logic: tie the marketing effort to something social and unconventional
• Controversy only works if there's genuine substance underneath — "if you do something controversial that was stupid, it just looks stupid"
• The formula: build something with real depth, amplify what makes it unique, then layer the controversial angle on top

Staying in school as an advantage

• Yale encourages students to either wait until graduation or drop out — few founders do both
• Johnson's view: being a student gives direct access to a community that is also your market
• Series used student proximity for marketing in ways a remote team could not replicate
• Raising the largest Ivy League round while staying enrolled is itself a signal meant to shift the norm
