IPOScoop is a subscription service providing predictions for IPOs' performance on opening day. Founded by John E. Fitzgibbon Jr. in 2006, IPOScoop also has lots of useful, free information as well. The site has a running list of the most recent 100 IPOs. Initially sorted by date, you can also sort by return rates and industry. Additionally, each company listed links to a company profile showing the business description, number of employees, date founded, contact information and revenues. They've even got a link directly to the companies' SEC filings. You'll also find a great chart showing "IPOs priced in the last 12 months sorted by Industry":
You can also see upcoming IPOs and links out to their S-1s and a handy list of other helpful IPO links. We've added IPOScoop to our list of favorite resources.
