On September 18, 2026, Infillion announced plans to acquire Foursquare, the location-data company. The announcement we reviewed did not state a price or an expected closing date.
What Infillion gets
- Foursquare says it has 100 million points of interest across 200 countries and 16 billion check-ins, with data from about 250 million devices in the United States.
- Infillion plans to pair that with purchase intelligence from Catalina, so advertisers can see whether ad exposure led to a visit and, with purchase data, to a sale.
What stays the same
Foursquare will remain an independent brand and keep selling its data, which trade coverage says includes selling to competing platforms. Infillion says the future of the Swarm and Superlocal apps will be evaluated.
Why it matters
Location data is one of the few ways to connect an ad to a physical visit, so owning the underlying place and visit data strengthens a measurement business. The open question is neutrality: whether Foursquare's data stays available to Infillion's rivals on fair terms.
What happened next
The deal had not closed in the sources we reviewed, and terms were not stated.
