Builders—students, independent developers, and engineering teams—struggle to find in-person and virtual hackathons and niche events because listings are scattered across dozens of platforms and local communities. Across 26 million global developers, that fragmentation translates to a $2.6B annual market (roughly $100 per developer per year on events, platforms, and discovery services) and routine missed opportunities for networking, recruiting, and skills development. I’d recommend a map-first discovery platform that aggregates hackathons, workshops, and co‑working events, uses AI-powered scrapers and NLP to auto-list and summarize opportunities, and combines calendar/trip planning, ticketing links, and local workspace recommendations into one workflow. For organizers the product would offer one-click listings, analytics, and paid promotion; for attendees it would surface filtered, geo-aware itineraries and cohort-based recommendations. This is an attractive moment: advances in scraping and NLP reduce curation costs, experience-first travel is driving event-centered trips, and fragmented supply creates clear demand for a unified view—hence a high market score of 90/100. Where the idea can win is a tight focus on quality and trust—verified listings, city-level supply density, partnerships with 20–50 event platforms in initial launch markets, and immediate value through map-based trip planning and cohort features. Challenges are real: competition is medium, building the two-sided network and moderating content will take time and capital, and revenue upside is solid but moderate (Revenue Potential 72/100), so a disciplined GTM into 10 pilot cities with organizer incentives is essential before scaling.
