Foursquare, the check-in and local search app maker, completed a $35 million Series D funding round and announced it has reached 45 million users.

During 2013, the company launched new versions of its app, an ad platform and real time recommendations. The service has seen more than 40 million user recommendations and five billion check-ins.

It secured a $41 million investment in April, shortly after launching the latest version of its app, which made the search functionality more prominent.

It was reported in August that Microsoft and American Express were both interested in taking a stake in the company.

The latest funding round comes from two new investors, DFJ Growth and Capital Group’s SMALLCAP World Fund. Barry Shuler, DFJ Growth managing director and former AOL CEO, has joined the Foursquare board.

Foursquare wasn’t specific about how it plans to use the investment but said it means “we can build our vision even faster “.
