Razorpay, Cashfree, or Stripe Atlas?

Razorpay/Cashfree if you charge Indian customers in INR UPI conversion is 2–3× cards. Stripe Atlas (Delaware C-corp) if 80%+ revenue is USD from global buyers.

Do I need to register a company to start?

No you can validate as a sole prop or with a partner and revenue up to ~₹20L before GST registration is compulsory. Register a Pvt. Ltd. before raising or hiring.

How do vibe coders in India actually earn USD?

Two paths: (1) Stripe Atlas + a Delaware C-corp for pure SaaS, or (2) Payoneer/Wise + freelancing/consulting alongside the product until ARR justifies incorporation.

Is the Indian market too crowded for AI tools?

Horizontally yes. Vertically for regional-language content, education (JEE/NEET/UPSC), D2C ops, and SMB WhatsApp automation the market is still wide open.
