Interwoven is a line of content management systems and related products. Previously a stand-alone company headquartered in San Jose, California, USA and founded in 1995, it was acquired on March 17, 2009 by Autonomy, which in turn was acquired by Hewlett-Packard in 2011. The Interwoven and Autonomy product lines became known as HP Autonomy. HP has since aligned the former Interwoven product lines to the HP Marketing Optimization business group.
