Build a focused event-discovery product that aggregates public listings from multiple sources, normalizes dates and locations, and presents strictly chronological results matching the user's filters. Each listing would clearly distinguish free, paid, sold-out, and price-unknown events, with links back to the original organizer or ticket seller. Begin with one city and a small number of high-demand categories, combining automated collection with manual verification.

Recent reviews show repeated deterioration in search quality and usability across several established event platforms. A city-by-city entrant can differentiate through trustworthy filtering and data quality without initially building ticketing, group management, or a social network.
