The Wall Street Journal's venture capital blog yesterday featured Texas-based startup Riptano, which received a $2.7 million capital infusion for its work in developing Apache Cassandra software.

Earlier this month Riptano announced a partnership with local firm Digital Reasoning on Cassandra solutions for government and commercial markets. Accordingly, the Franklin firm gets this shout out in the WSJ piece:

Digital Reasoning Systems, a software company in Franklin, Tenn., is working with undisclosed U.S. government agencies to deliver a Cassandra-based system for intelligence-related applications–such as looking for suspicious terms and connections between people in huge quantities of documents in a variety of formats, including Word documents and transcripts of recordings of phone calls, says Dave Danielson, its vice president of marketing. “They have some problems in finding bad guys in hundreds of millions of documents,” he says.

Digital Reasoning’s own software helps store and categorize such unstructured information in Cassandra, using the technology to help narrow down searches that might pull up millions of documents into the ten to thirty or so that human analyst need to look at, Danielson says.
