Location-based social networks Foursquare and Gowalla are accumulating users (and headlines) with impressive momentum. While both companies have been vocal about reaching major milestones, we wanted to take a closer look at the data behind these accomplishments. Based on our estimates, Foursquare is not only bigger in terms of both users and venues, but it also is growing at a faster clip than Gowalla.
For the past four weeks, we’ve been monitoring the Foursquare and Gowalla APIs to track growth rates, as well as to sample users and venues. This data was loaded into an RJMetrics Dashboard, which provided the results found here with just a few clicks. We will keep these estimates up-to-date with fresh data and you can view them any time at our Startup Data page.
Here are a few highlights from our findings:
As of today, Foursquare has just over 1.9 Million users. Gowalla has around 340,000.
Over the past 30 days, Foursquare averaged 12,900 new users per day, while Gowall averaged 1,370. Recent new user acquisition by day for each service is shown in the chart below.

Foursquare is clearly acquiring users at a much higher rate than Gowalla, and this ratio of new Foursquare users to new Gowalla users is shown below. It averages almost 10-to-1.

The numbers become even more interesting when you consider each company’s daily growth rate. This is the number of new users in a given day divided by the total user population from the previous day.
Since Foursquare is growing off of a much larger base, you might expect their percentage growth to be smaller than Gowalla’s. However, as shown below, their daily growth rate averages about 75% higher than Gowalla’s.

Similar trends appear when we look at daily venue growth. Currently, Foursquare has about 5.6 Million venues (or about 3 per user) and Gowalla has 1.4 Million venues (or around 4 per user). The rate at which new venues are being added is shown below:

Foursquare and Gowalla share different information about their users via their respective public APIs, revealing different types of statistics about each population.

As with users, the available data differs between the two services.

In most cases, this level of detail wouldn’t be accessible from the outside looking in. However, Foursquare and Gowalla have a few common characteristics that made it possible:
Our scripts tracked the maximum registered user and venue IDs each hour, along with randomly sampling data points throughout the population. This gave us a “density factor” so that we could adjust the absolute numbers to reflect deactivated accounts, deleted venues, and other skipped IDs.
In the end, our sample size consisted of about 82,000 data points from Foursquare and 36,000 data points from Gowalla. As with all such analyses, the results in this report are only estimates and could be skewed by flaws in our sampling methods or unconsidered outside factors.
Both services are showing impressive growth and are accumulating moutains of valuable, fascinating data. However, Foursquare is clearly the dominant player and their lead is increasing every day.
Be sure to keep an eye on our Startup Data page to track how these numbers progress over time. With Foursquare approaching the 2 Million member mark, it appears that this may only be the beginning.
Foursquare is a geographical location based social network that incorporates gaming elements. Users share their location with friends by “checking in” via a smartphone app or by text message. Points are awarded for checking in at various venues. Users can connect their Foursquare accounts to their Twitter and Facebook accounts, which can update when a check in is registered. By checking in a certain number of times, or in different locations, users can collect virtual badges. In addition, users...
