Interwoven Letter to Web Solutions Customers at Close

Dear Interwoven Customer,

Today we finalized the acquisition of Interwoven by Autonomy, the clear leader in enterprise search and the front runner in Meaning Based Computing. Autonomy has been one of the world's fastest growing software companies for the last few years and in 2008 reported year-over-year revenue growth of 47%. Its technology is relied upon in the most critical of applications and can be found inside industry leading products from companies such as Oracle, Symantec, and HP. The newly combined organization positions Autonomy as one of the strongest companies in enterprise software, with more than 20,000 customers and 2,000 employees and a $4B market capitalization. I invite you to learn more about Autonomy at www.autonomy.com.

We have a clear leadership position in several fast-growing markets, and a vision to fundamentally change the way organizations discover, analyze, and manage information. Therefore, the market for Web Solutions is strategically important to Autonomy and it's the area we are making the most significant investments in research and development. We value Interwoven's decade of experience working with interactive marketers to understand how they create and deliver content and their need to test, optimize and analyze combinations of content and layout. As an Interwoven customer, you can now leverage Autonomy's ecommerce technology to recommend complementary products, automatically segment buyers into groups, and analyze newly emerging trends in buyers' behavior. Interwoven's web solutions can also be married with Autonomy's contact center solutions to form a complete view of the customer and to drive a significant increase in ROI.
