PROS Holdings (NYSE:PRO) seems more like a university than an enterprise-software company. Among its 300 employees, 100 have advanced degrees and 20 have Ph.D.s. But these folks do more than talk about exotic theories; they've built a solid business over the years. So far, Wall Street likes what it sees. On PROS Holdings' IPO yesterday, the stock surged 17% to $12.85.

Over the years, the main focus for enterprise-software companies has been to find ways to automate processes and find cost savings. While this is fine, these firms have been missing out on perhaps a bigger opportunity: How can software improve revenues?

That's the focus at PROS. The company develops software that helps with pricing and revenue optimization. The technology uses advanced statistical approaches that leverage real-time and historical data from systems such as Oracle (NASDAQ:ORCL) and SAP (NYSE:SAP).

Pricing optimization is often a haphazard process, and money can often be left on the table. A recent study from Gartner points out that a 1% improvement in pricing can produce an 11% increase in profitability. In comparison, a 1% improvement in fixed costs serves up only a 3% increase. And optimization has turned out to be a nice growth business for PROS. It's shown profits for the past eight years. In 2006, revenues increased 31% to $46 million.

PROS does face competition from rivals such as Revenue Technologies, Vendavo, Zilliant, SAP, Oracle, and JDA Software (NASDAQ:JDAS). What makes PROS different is that it has developed solutions over 20 years, is a thought leader in the industry, and has traction with major clients. Another big advantage is its group of highly qualified scientists and experts.

However, PROS' valuation stands at six times trailing revenues. Even though the company is growing nicely, this is still not cheap compared with other enterprise software companies. So while the company has a big market opportunity and a strong product offering, Foolish investors should probably wait to try to get a better value on this one.
