Two rounds of layoffs have left Austin-based software maker Crossroads Systems with just 48 workers, according to the Austin Business Journal. The company develops software designed to connect and protect data for enterprise storage and cloud computing. Its headcount stood at 99 last March, when it was pinning its turnaround hope on StrongBox, a plug-and-play device designed to manage tape storage systems. The company now employs 22 workers in research and development; 14 in sales, marketing and business development; and 12 in general and administrative support and operations functions, it said in a filing with the Securities and Exchange Commission. In December, the company ended an agreement with Iron Mountain Information Management that called for Iron Mountain to invest $5.2 million as part of StrongBox’s development. Crossroads filed lawsuits in November against Dell and two foreign tech companies alleging infringement of patents for its data-storage router and storage network technology. It also alleged patent infringement in lawsuits against 3Par and six other companies in 2010. The company fired longtime CEO Robert Sims last May and made Richard Coleman permanent CEO in November. Though it narrowed its loss in its fiscal fourth quarter, it still posted a loss of $14.3 million for 2013.
