Hulah is a safety-first dating app that had a problem: 90% women, not enough matches. I joined at 20k users and led a visual redesign—new color system, typography, and components. At 40k users, I designed a referral system based on a key insight: women protect their single friends. If they trust the app, they'll invite men they vouch for. The app hit 250k users, broke top 9 on the App Store, and got featured on Good Morning LA—fueled by the founder's viral TikToks.
