Mainstream matrimony apps were not built for tribal families. They ask about caste and horoscopes, not tribe and clan; they are built for individuals, not families; and very few tribal families use them.
Vivaham is built the other way around: family-led, within community rules, with verification, consent and safety at the centre.
Vivaham is operated by HappyChases Media Works (OPC) Private Limited, Raipur, Chhattisgarh.
