Foursquare, the fast growing location-based social media platform, which now has 1 million active users and is adding about 15,000 per day, is dealing with problems in scaling the service to keep up with demand.

To keep up with demand and stay ahead of the small and big players who are targeting the space, Dennis Crowley, founder, is looking for additional capital, he told me at the TechCrunch Disrupt conference earlier this week in Manhattan.

Note: Dennis does not make the comment about raising funds in this video.  He said this this during a conversation with the reporter.

We saw him huddled back stage at the event with VC Fred Wilson, an investor.
