GlamUp

GlamUp is an AI-powered beauty app that lets users upload a photo to receive facial analysis, color season analysis, makeup guides, and personalized product recommendations. It launched in April 2024 and scaled to over 1 million users and $150K monthly recurring revenue within six months — entirely without paid ads or VC funding, relying on viral referral loops and behavioral psychology.

Founded by Nicole Cheung (CMC '25, Psychology/Economics) alongside a YC '21 alum. After GlamUp, Nicole went on to co-found Sprout, hitting $250K MRR in 8 months for a combined $400K+/month across both products.
