How a 20-year-old college student became a viral startup CMO

Executive overview

Most startups chase virality without understanding what drives it. Eunice Lai, a college student with a film background, became CMO of Series and generated millions of impressions by doing the opposite of everyone else — leaning into authenticity, absurdity, and platform arbitrage.

Her approach: find a real, niche behaviour, amplify it with a consistent persona, and let the audience participate. The result was three viral launch videos, 3,000+ RSVPs at a NYC Tech Week event, and inbound interest from investors.

The secret to startup virality is not polish — it's a fully committed persona backed by genuine behaviour.

The Hinge-to-Twitter flywheel

• Eunice started tweeting "build in public" but found it too crowded to stand out.
• She turned real Hinge conversations about her startup job into Twitter content — nothing fabricated.
• First viral tweet named her date "Jason [Hinge]" — reducing him to a data point made people laugh.
• She later physically walked that date through the product onboarding process and converted him into a user.
• The campaign was reflexive: Twitter followers tried to find her on Hinge, creating ongoing content loops.
• Playing the "SF tech girl in New York" archetype gave her a consistent, recognisable persona to lean into.
• Commitment is required — a half-sent persona reads as inauthentic; full commitment lets smart people play along.

Borrowing clout and collab mechanics

• A founder building a competing dating app (Cupid) reached out to feature Eunice in his launch video.
• He used her dog's death (publicly posted on Twitter) as controversial bait — generating outrage-driven engagement.
• The video hit 1.5M views; both parties gained followers and exposure.
• Key principle: collabs work when there is a logical connection between the two parties; clout-borrowing without relevance fails.
• Outrage and absurdity drive virality — being willing to tolerate backlash is a competitive advantage.

Content strategy: do the opposite

• Default trend on any platform becomes invisible — differentiation comes from reversing the dominant format.
• When vertical video with loud text and rage-bait hooks was the norm, Eunice switched to calm horizontal video with no heavy edits.
• A 90-second unedited talking-head video got only 35K views but converted 200-250 followers — a high signal-to-noise ratio.
• Hooks still matter, but the format can be the differentiator.
• Challenge and day-by-day formats work because curiosity drives sustained follow-through from audiences.

LinkedIn and the Hampton's intern campaign

• LinkedIn is undervalued — high-quality followers, unsaturated, and the content bar is low.
• For Series, Eunice ran a race campaign: 2,500 applicants for intern spots, then challenged 150 finalists to compete via LinkedIn posts.
• Social proof cascaded: once 1-2 people posted publicly, 100+ others followed within two days.
• The top competitor invited 120 people in a single day by maximising every channel available.
• Guerrilla gifting (donuts, doormats) is an emerging trend — physical acts that trigger social proof online.

Hiring and managing content people

• Look for potential, not follower count — the ability to turn a boring topic into a story is the signal.
• Founders should build their own personal brand regardless: it outlasts any single company.
• Big creators are good at building their own brand, not necessarily someone else's — vet for this distinction.
• Avoid overprescribing to experienced creators: creative burnout is real and formulaic pressure kills output quality.
• KPIs should be qualitative first (brand identity communicated, audience takeaway) and quantitative only once there are data points.
• A good pitch from a founder includes target audience insight and a product-content connection, not just "make me go viral."

Choosing where to work

• Eunice turned down offers paying 2-3x more to join Sonder, built by close friends from Carnegie Mellon.
• Strong conviction in a mission and working with trusted people outweighed short-term pay.
• Founders who pitch without thinking about their audience signal a culture problem — that reflects on the product too.
• Personal brand accrues to the individual, not the company — build it early regardless of where you work.
