Diageo-owned brand Captain Morgan is one of the first to use Foursquare’s new post check-in ads service.
The new feature allows brands to target users after they check in at locations relevant to their brand.
For Captain Morgan, when a user checks in at a bar, nightclub or restaurant for example, an ad will appear on their screen suggesting they order a drink with Captain Morgan.
The rum brand kicked off the campaign earlier this month and will run it for the next four to six weeks, according to AdAge.
From August, other Diageo brands, including Smirnoff, will start using Foursquare's post check-in ads.
Meanwhile, brands like Toys R Us and Babies R Us have used the service to target users who check in at family-friendly locations such as parks, playgrounds and public swimming pools.
Foursquare has been relatively quiet on the new feature. It was a leaked pitch in April that revealed exactly how the exploring app planned to make money via the check-in service.
The company reportedly sells post check-in ad space on a Cost Per Action basis, although the exact figure has not been revealed.
