Intro

Idea

In 2022, I spotted a portable breathalyzer while browsing Alibaba. It struck me: “Isn’t it almost silly that in this day and age, we still don’t know how intoxicated we are after a couple of drinks?”

I believed a consumer-friendly, affordable device could ride on DUI awareness trends in the U.S. and appeal to both individuals and parents concerned about safety. With that conviction, I bulk ordered 50 units from Alibaba and started running ads across multiple platforms.
