The opportunity
Chaat is sold on almost every busy street, near schools, temples, bus stands and market lanes, in every Indian town. Most of these sellers are single carts or tiny stalls that still make condiments by hand. Packaged chutney exists in retail bottles, but those are sized and priced for households, not for a cart that goes through a tub in a day or two. That leaves room for a local maker who supplies in bulk, at a vendor friendly pack size, and who can adjust sweetness and spice to what that neighbourhood likes.
Demand rises around festivals, evening crowds and summer, when chaat sells most.
