Over the past 12+ years, Foursquare has developed a map of the world using first party data derived from over 14 billion explicit check-ins from our consumer apps. We’ve also merged with leaders in the space to increase our breadth of sources and improve our ability to ingest, aggregate, clean, cluster and summarize billions of location data references. We have also accumulated numerous geographic datasets, geospatial assets, and validation rules.

Foursquare combines our first party data, ground truth datasets, web resources, and partners with third parties to incorporate updates and ensure near 100% coverage. We also partner with trusted listing syndicators that ship daily updates for millions of places on behalf of leading brands, chains, and small business owners. They actively manage their POIs through regular data updates.

Our datasets are ingested into our proprietary processing pipeline, which applies our machine learning algorithm to de-dupe, normalize, and enrich the data. And our validation method is best in class. In addition to employing our proprietary technology, we incorporate human validation by a dedicated community of Superusers (see Glossary). Foursquare also conducts Human Verified Audits of our points of interest, ensuring we deliver places that are real and open for business.

A rigorous quality assurance program allows us to improve the quality and fill rates of the data for commercial use. The result is the world’s leading independent location platform.
