Financial terms were not disclosed.

Todd Olson, founder and president of 6th Sense, will remain with Rally and lead remote development operations, a company spokesperson said. All 6th Sense employees will join Rally, the spokesperson added.

“If you can’t accurately measure software delivery, then you can’t improve it,” Tim Miller, Rally’s chief executive officer, said in a statement. “We’re thrilled that we were able to take advantage of this opportunity to incorporate 6th Sense Analytics’ rich reporting capabilities to the Rally platform, as well as add a phenomenal development team to our staff.”

6th Sense Analytics closed on $5 million in venture capital and added a new investor in January 2007.

Core Capital, which is based in Washington, D.C., led that funding. Intersouth Partners, which is based in Durham and backed 6th Sense with its first funding, also participated.

6th Sense offers a hosted, or software-as-a-service, solution that tracks development of software projects. The company, which launched in 2004, has raised $6.7 million in all.

Rally focuses on so-called “agile” development that encourages collaborative design and creation of new software solutions.

“This move will provide Rally customers with more access to project data and enable them to easily report on their project’s progress and quality status throughout the Agile development lifecycle,” a spokesperson for Rally software said.

“These new capabilities will also help development teams better manage the costs of their projects by giving them real-time insight into their progress and provide them with valuable data to support their projects at the management level,” she added.
