Foursquare supplies location technology to over 125,000 developers

"While the unbundling effort was a risky bet, it seems to have paid off for the company. Both apps have over 50 million monthly active users as of 2016, which has allowed Foursquare to put their foot on the gas with enterprise products.
For example, Pinpoint by Foursquare (an advertising product) now boasts more than half of the Ad Age 100 as advertisers. Attribution by Foursquare lets those brands measure how effective that advertising is. Attribution more than doubled revenue in 2017.
Developer tools are also an integral part of Foursquare’s business. The Pilgrim SDK and Places API “grew substantially,” according to a post by CEO Jeff Glueck, and now provides location tech to 125K+ developers.
Foursquare added 50+ new roles over 2017, including positions in engineering, sales, creative, business development, marketing, and ops. In 2018, the company is opening a new engineering office in Chicago, and plans to grow the team by 30 percent over the course of the year."
