Wait, there's more: the initial offering of 7.2 million shares was upped to 8.2 million shares. So instead of pricing 7.2 million shares at $24 (the mid-range) and raising $172.8 million, they priced 8.2 million at $31, raising $254 million.

Think there's some happy folks over at Tableau? The average insider owns the stock at 43 cents. That's right: 43 cents.

Not bad, eh? A software company? It's simple: Big Data. It's the new magic word, like "cloud computing" was a year ago. Their software allows customers to analyze large data sets using proprietary drag and drop commands. The company's description of what it does is refreshingly free of a lot of the jargon terms that characterize so many company descriptors. They help people see and understand data, to quickly analyze, visualize and share information. Get it? And no leveraged buyout here.

And anyone can hire them. If you run a pizza delivery service, you can use their software to analyze your phone calls and where your deliveries are going. And you can hire them if you're JP Morgan to analyze any data. It's completely scalable.
