Foursquare has raised another $41 million and plans to use the funds to build more features.
In a blog post on Thursday, Foursquare co-founder and CEO Dennis Crowley said the company has been able to raise the new funding from Silver Lake Waterman as well as its existing investors, Andreessen Horowitz, O'Reilly AlphaTech Ventures, Spark Capital, and Union Square Ventures.
Crowley wrote that the new funding will be used to build more tools to help businesses connect with customers, improve search, and build a "location layer for the internet" that will allow other companies to use location in their apps.
Foursquare's announcement comes a day after it celebrates its 3.5 billionth check-in, 500 million of which were made in the first quarter of 2013. It has 1.3 million businesses participating, and a user base of 33 million.
Now in its sixth major revision of its application code, the company is moving to produce personalised recommendations based on where a user is and where they last checked in.
It is not the first time that Foursquare has received a major funding round. In June 2011, it raised $50 million in venture capital, valuing the company at $600 million, but a lack of clarity as to how Foursquare would raise funds left many asking how it could be profitable.
