eiStream, Inc. announced the acquisition of electronic document management and workflow provider Lexign, Inc. Lexign markets two products: Keyfile, a document management and imaging repository that was developed in 1989; and Flow, a Microsoft Exchange-based workflow automation tool. Lexign offers document tracking, management, organization and version control. The Keyfile client interface offers the look and feel of a Microsoft Windows desktop or a Web browser, depending on user preference. The Keyfile Document Server (KDS), an object database, serves and stores documents and implements business processes. Lexign Flow is a business tool that automates mission-critical business processes regardless of complexity. It may be deployed in a single department, across an enterprise or in business-to-business environments. Lexign was founded in July 2001 with the merger of icomXpress (formerly Keyfile), thinkXML and E-Lock Technologies. www.eistream.com
