Research firm IDC has a new list you might want to pay attention to: 10 Innovative Application Companies Under $100M to Watch.

"IDC has projected 2009 as a year of accelerated adoption of new business models for applications, including software as a service and open source, as well as Web 2.0 capabilities and functionality," says Michael Fauscette, group vice president, Software Business Solutions, IDC.

To pull this list together, they solicited entries from vendors who make enterprise software. Vendors had to meet the financial criteria and demonstrate one or more aspects of three key trends, including Web 2.0 capabilities in the Enterprise, SaaS, BPO or open source solutions, and new business models for software use by service providers. The selection critiria came from the  IDC's Worldwide Applications 2008 Top 10 Predictions.

So who made the list? There are more than a couple of names we recognize, with a particular focus on social computing: Jive Software, Telligent, Atlassian, Kaltura and Trampoline Systems Ltd., among others. There's no specific order to the list, in case you are wondering.

IDC profiles each of the 10 companies in this 9 page report -- that'll run you US$ 3500.

Interesting to note that Atlassian, Jive and Telligent also made Gartner's Magic Quadrant for Social Software in the Workplace.

This is just further evidence of the growing strength of social software in the enterprise and its potential to displace content management as a key technology.
