Lovers of anything with "cloud computing" or "software as a service" in its description will have plenty to chew on shortly:
1) Paylocity (PCTY), cloud-based payroll and human capital management software;
2) Rubicon Project (RUBI), a digital ad exchange that exists in between publishers of websites and buyers of advertising;
3) Castlight Health (CSLT), a platform to help employers who want to become self-insured. This company is being carefully watched: they have less than $20 million in revenue, but may open with a $1 billion market cap. One of the co-founders (Todd Park) was a co-founder of athenahealth;
4) Amber Road (AMBR), cloud-based global trade management software;
5) Q2 Holdings (QTWO), cloud-based virtual banking software;
6) Rimini Street (RMNI), enterprise software support services;
7) Aerohive Holdings (HIVE), cloud-based WiFi and routing products;
8) Borderfree (BRDR), e-commerce software to U.S. retailers to market and sell to customers worldwide;
9) 2U (TWOU), a cloud-based software for online educational content; and
10) A10 Networks (ATEN), network technology that optimizes data center performance.
There are also a small group of non-tech companies that will go public, including:
1) La Quinta Holdings (LQ) one of the largest budget hotel operators in the U.S., which is backed by Blackstone;
2) Ally Financial (ALLY), the leading global auto finance company, formerly a unit of GMAC, which filed for a $500 million offering way back in 2011 and may finally be ready to go public.
These are only those who have already filed S-1's indicating they will likely go public shortly. The NYSE has prepared dozens of pitches to companies that are looking to go public, but have not yet filed a public S-1.
