Mindquarry, founded in July 2006 in Germany, shut down after failing to convince that its alternatives to Microsoft's Sharepoint Server and IBM's Lotus Connections wee viable.
"We could not convince our investor to keep financing our endeavor," Mindquarry says on its Web site, referring to HassoPlattnerVentures, an organisation funded by SAP co-founder Hasso Plattner.
The investment firm decided Mindquarry would be unable to compete with Google, Microsoft and IBM "because they are all investing a lot of money in this collaboration topic," says Alexander Saar, who founded Mindquarry along with Alexander Klimetschek and Lars Trieloff.
Commercial services and products provided by Mindquarry died with the company. But before closing its doors Mindquarry released an updated version of its open source software, a platform for file sharing, task and project management, team collaboration and wiki editing. The source code can still be found on Mindquarry's Web site and Sourceforge .
The three Mindquarry founders have since joined the product development team at Day Software, the vendor announced on Tuesday.
Day Software makes enterprise content management tools and says the addition of Mindquarry's founders is aimed at expanding the vendor's presence in the social media and open source markets.
The former Mindquarry personnel are now responsible for Day's collaboration product, which became generally available in October with wiki, blog and calendar applications. "What we see is there is a lot of space for improvement of these tools and much need for integrating these tools with each other," Saar said.
Day Software says it was impressed by the ease-of-use offered by Mindquarry's collaboration software.
"Designed to combine integration and consultation services with an open source platform, Mindquarry was developed in Java and built upon a scalable REST architecture with AJAX and Web 2.0-style user interfaces," Day said.
While Day is not an open source vendor, it has contributed code to some open source projects and has open source components in its own products, said Santi Pierini, senior vice president of marketing.
"We are exploring business models that will allow us to go deeper into the open source market as well," he said.
