Eunice Lai - This 20yr old girl is a marketing genius…

Eunice Lai, a college student who ran marketing at AI social network Series and has since joined her friends' startup Sonar, on Gen Z startup content. She turned real Hinge chats about her 'startup' into viral tech-Twitter posts, then onboarded one date as a user in person. For Series' Hamptons TV show she turned ~2,500 LinkedIn applicants into a 150-person race with invite challenges; after the first posts, 100+ interns posted on LinkedIn in 2 days. Also: a collab launch video for dating app Cupidly (1.5M views), calm horizontal Reels, and trusting creators with qualitative goals.
