Summer's almost out, but the IPOs are already lining up for the fall. 

Yet another company began prepping paperwork for an Initial Public Offering - this time, it is Colorado-based Ping Identity ($PINGIDENTITY), which is heading for public markets likely this fall, which is the same time investors will be pumped for the arrivals of companies like WeWork ($WEWORK), SmileDirect ($SMILEDIRECTCLUB) and Cloudflare ($CLOUDFLARE). 

Ping was growing, leading up to its IPO paperwork and headcount, which are still on the rise. We can tell this through our LinkedIn ($NASDAQ:NSFT) Employee Count, which measures how many people identify a company - like Ping - as their current place of employment. Ping Identity said in its S-1 filing that its headcount ending the first half of the year was about 897 - and we can tell from our first chart that the figure has grown 6% in the time since then.

Already, Ping Identity has posted impressive growth. But, as our second chart shows, it's still hiring, as well. The web security company counts major investors like private equity firm KKR ($NYSE:KKR) and VCs Draper Fisher Jurvetson and General Catalyst among its pre-IPO investor base and has amassed more than $120 million in funding over the years, according to reports. 

Last but not least - evidence that Ping's products have a big social following, too. Although the data lapsed in mid-2018, we can still tell from the last available data point that Twitter ($NYSE:TWTR) followers were tracked, to current day, makes for a 26% increase. 

About the Data: 

Thinknum tracks companies using information they post online - jobs, social and web traffic, product sales and app ratings - and creates data sets that measure factors like hiring, revenue and foot traffic. Data sets may not be fully comprehensive (they only account for what is available on the web), but they can be used to gauge performance factors like staffing and sales.
