The story
Two brothers, one weekend, every watch party
Brothers Dennis and Stefan Tan run Dashmote, an Amsterdam-based data company that maps the world's food-service and hospitality market for brands like Coca-Cola, Heineken and Red Bull. Ahead of the World Cup they had a very normal problem: where do you actually go to watch the games? Google a city and you get last tournament's listicles; ask a bar and you get a shrug.
So one weekend they pointed their venue-mapping know-how at it and built Watch Party Radar.
A map that reads what venues themselves announce on their Instagram, websites and event feeds, verifies it, and pins it. It launched with 69 cities and grew every day of the tournament to 352 cities, from every 2026 host city to the night-match cafes of Amsterdam.
The final was played on July 19. The radar kept going: its early sign-ups voted on which sport it should cover next (Formula 1 and club football topped the poll), and the same evidence engine now maps where to watch seven sports year-round, with the entire World Cup edition preserved as a per-city archive.
Interviews, data cuts (busiest watch-party cities, team-by-team fan bases, sport-by-sport venue counts) and city-level numbers for your market are available on request; we usually turn requests around same-day.
