How this map is made. Every startup here has raised money in rounds we track. Each is placed at the city we hold for it, matched to that city's position in GeoNames (cities of 15,000 people or more; geonames.org, CC BY 4.0); startups without a city on record count in the totals but not on the map. Rebuilt nightly; updated 15 November 2026.
