Just three years back, Jason Siu was a teenager in high school selling stickers for $3 on Snapchat to earn money for car parts.
Now, his side project, Invalid.jp, pulls in over half a million dollars each year. The business, which started with stickers, now sells various car accessories like LED mirrors and customized license plates.
A college junior at the University of Hawaii, Siu sources his merchandise in bulk, adds unique touches, and sells them at a markup. He recently rented a warehouse to house his growing venture. Until this point, he operated out of his parents’ small apartment in Honolulu.
Some of his profits have come from a surge in popularity on TikTok. One of his posts showcasing the light-up stickers brought in $38,000 in a single day.
Though not every day is a big payday, Siu has found ways to keep earnings steady, using social media advertising to maintain a regular income.
