Serena Software (NASDAQ:SRNA) has unveiled its new online marketplace to accelerate the creation and use of business mashups. Mashup Exchange allows companies to find, buy, and sell pre-packaged mashups, Web services, and professional services for free.

The new service allows users to create on-demand communities around software offerings or practice areas so they find the mashups and resources they need. Companies can create private MicroExchanges for secured internal interchange between IT and business units or open communities to encourage debate, collaboration, and crowd-sourcing.

"Serena Mashup Exchange encourages innovation and collaboration among business users to solve everyday business problems, while also ensuring that IT governance standards are upheld," Rene Bonvanie, senior vice president of Serena Software's global marketing for partnerships and online services, said in a statement.
