India runs on weddings. With an estimated market size of over ₹10 lakh crore, roughly $130 billion, and by some estimates nearly twice the size of the US wedding market, India's wedding economy ranks second only to food and grocery in consumer spending. Between 9 and 11 million weddings happen in the country every year, each a multi-day, multi-city, multi-event production involving hundreds of families. And yet, for all that scale, the entire coordination of a wedding still runs on spreadsheets and a dozen overlapping WhatsApp groups. Discovery got digitised long ago; you can book a venue or find a photographer online in minutes. But the actualrunningof a wedding, who's invited, who confirmed, who's landed, who needs a room, whose ID card is lying in which chat, never got software worth the name. Gurugram-based Weddingkart, founded in 2023 by ex-Nykaa Distinguished Engineer Mayank Jaiswal, was built to fix exactly that. Weddingkartis anAI-first, WhatsApp-native wedding management platformbuilt for professional event managers and DIY couples across India and the UAE. On Weddingkart, event managers and couples import their guest list from Excel and manage the entire event — invitations, RSVPs, travel-ticket collection, ID uploads, announcements, and thank-you messages — from a single dashboard. Every guest interaction happens over WhatsApp. Underneath, AI does the heavy lifting: reading documents, linking scattered guest data, and answering questions for both guests and planners. The defining design choice is what guests donothave to do: download anything. No app installation, no new account for a celebration they attend once. Every RSVP, every travel-ticket share, every uploaded ID comes back through WhatsApp, the app that Indian guests already open dozens of times a day. To date, Weddingkart has helped event managers and couples manageover 50,000 guests across 100+ weddings, and holds a4.8-star ratingon the App Store. Crucially, Weddingkart isnot a vendor marketplace. It does not sell catering, décor, or venues. It is the AI-powered operating layer for the guest side of the wedding — software that runs the event, not a directory that finds suppliers for it. TheIndian wedding marketis one of the largest and fastest-growing consumer segments in the world. Independent trackers project it compounding at mid-teens growth rates for the next several years, driven by destination weddings, longer multi-event celebrations, rising guest counts, and a fast-expanding NRI segment. The problem in this market was never the size of the opportunity, it was the tooling. A professional event manager in India routinely handles300 to 2,000 guests per wedding, across three to seven events, over several days, while running five to ten weddings in parallel during peak season. The infrastructure for that level of coordination? Paper lists, Excel files, Google Forms, and WhatsApp groups where the latest headcount is whatever was typed last. Weddingkart's thesis is that the
