Koders allows users to search for open source software code. It officially launched a few weeks ago.
From the Interview
BK: What's the revenue model behind Koders.com, and how do you make money?
JT (Koders Co-Founder): Our revenue model has three dimensions; first, there is the revenue generated through banner advertising on the Koders.com search results pages. Second, we are working on an Enterprise Edition of the search engine to be released this Fall. The Enterprise Edition, which indexes the code base within and outside of the firewall of an organization, is currently in beta with a select few customers. Third, we are planning to syndicate data and analyses generated from the Koders.com search traffic. These reports will provide analysts, the media, even application developers, with trends and insights into most common searches, most popular projects, most popular languages, etc. In essence, we are able to identify what's happening in the OSS community and pinpoint areas of opportunity.
