The idea

“[ "Persona: A 32-year-old independent yoga instructor in Toronto who spends 6 hours/month manually scheduling classes and chasing late payments. Current behavior: Uses WhatsApp groups and bank transfers to coordinate with students. Pain: Loses ~6 hours/month in admin work and ~$150/month in missed payments. Solution: A lightweight scheduling and payment link that plugs directly into WhatsApp chats, auto-tracks attendance, and locks spots once paid—replaces manual coordination. Distribution: First 1,000 users via targeted outreach in Canadian yoga Facebook groups and partnerships with yoga mat retailers offering free trial codes. Unit economics: $12/month subscription; CAC ~$25 via ads; payback in 2 months with 40% conversion from free trial. MVP & timing: 2 developers can ship a WhatsApp-integrated scheduling/payment link in 4 months; WhatsApp recently opened APIs for SMB tools, making timing ideal. Defensibility: Network effect from student groups and proprietary attendance/payment data builds switching cost." ]”
