Die vollständige Geschichte
I'm from Brazil and built CSS Scan because I always wanted to know what border-radius, box-shadow, or font-family an element I see has.
Fast Progress
It took me 9 months to get the first $10,000 and just 9 more months to get an additional $60,000.
Organic Growth
I didn't spend money on paid ads - I let my product's effectiveness do the work. 7,000+ people from 116 different countries use my extension.
- First $10K: 9 months
- Next $60K: 9 months
- Users: 7,000+ from 116 countries
