Idea validation · checked 11 November 2026

Get strangers to commit something real, an interview, a pre-order or a signed letter of intent, before you write any code.

Ask people about the last time the problem happened, never about your idea, then deliver the outcome by hand or put up a one-page offer with a price and count who pays. In India, find them in WhatsApp groups, trade associations and on the shop floor, and treat a polite yes as no evidence. You have validation when strangers pay or keep chasing you for it.
