Why We Built Our Entire SaaS on WhatsApp Instead of Email (And What Happened Next)

Short summary

Dancely built a dance studio SaaS entirely around WhatsApp instead of email or apps because emerging markets like India and Brazil have 90%+ WhatsApp adoption vs. 15-20% email open rates. Architecture centered on WhatsApp OTP, automated fee reminders (85% reduction in defaults), and broadcasts. The founder acquired 76 studios across 50+ countries with zero paid marketing, proving underserved markets unlock exponential growth.

  • Dancely built WhatsApp-first SaaS targeting dance studios in emerging markets
  • 90%+ WhatsApp open rates vs 15-20% email in India/Brazil drove all architectural choices
  • 76 studios acquired across 50+ countries with zero paid marketing
