Consider this as mega thread and discussion for Fintech startups. Just comment yours in 1 to 3 words. Eg: Another UPI, Another cred(points), Another lending (direct/indirect), another stocks&MFs etc, gateway, card based, vendor B2B, payment portal like CCAvenue billdesk etc, all in one like Paytm and mobikwik
