My Chrome extension made $217 in its first week — breakdown by country
I built Wapes AI, a Chrome extension for WhatsApp Web (bulk messaging + AI CRM). Launched it 7 days ago with zero ads, just cold outreach and posting in relevant communities.
Results so far:
- 10 successful payments, $217 total, only 2 failed charges
- Revenue split across Argentina ($127.49), Peru ($44.99), Colombia ($15), Mexico ($14.99), and Chile ($10)
What surprised me most: as a solo dev with no big following, having paying users across 5 countries in week one proved people will pay for a Chrome extension that solves a real problem — even without brand recognition.
What worked:
- Talking to potential users before building anything
- Charging from day one instead of "polishing" first
- Posting in communities where WhatsApp/small-business users already are
Happy to answer questions about building and monetizing a Chrome extension, the tech stack, or how I got early users.
