SEATTLE — January 16, 2002 — Insightful Corporation (NASDAQ: IFUL), a leading provider of enterprise software solutions for data analysis, today announced availability of StatServer 6.0, a major upgrade to the company’s software for data analysis via the Web. StatServer 6.0 provides easy access to high-end analytics and graphical reports that reveal patterns, trends and relationships in data. New data analysis and visualization features help users access, analyze and share information faster using a simple Web browser.

StatServer 6.0 provides a proven platform for Web-based business analytics, which helps decision-makers make smarter decisions enterprise-wide. The technology delivers advanced analytical methods that increase the richness and reach of information. For example, sophisticated predictive analysis methods and graphical drill-down reports make it easy to make well-informed decisions by showing not only what has happened, but also what is likely to happen.

Industry analysts believe the trend toward sophisticated analytics has just begun. "Insightful is on the leading edge of analytical software, offering a sophisticated, flexible platform that presents clear results and accurate estimates via a simple Web interface. Predictive analysis, which relies on sophisticated models of probability, gives decision-makers a necessary new way to anticipate opportunity, reduce risk and improve efficiency," said Dan Vesset, IDC's research manager for data warehousing and information access. "Graphlet technology featured in StatServer 6.0 simplifies access to high-end analytics by presenting interactive charts via the browser. StatServer makes it easy to access, analyze and share business intelligence, which makes it easier to make good decisions."

Customers such as Pioneer Hi-Bred International, Inc. use StatServer to deliver information to decision-makers across the business. "StatServer integrates easily within our application environment standardizing analysis across the research organization facilitating decision-making. StatServer makes S-PLUS data-visualization tools easily accessible to our business users.

"We’ve reduced our analytic development time by 50 percent and delivered twice as much functionality with Insightful’s technology. We can prototype new analysis techniques quickly, and the software scales as we add more users to our system," said Dr. Ken Yourstone, research analyst, Pioneer Hi-Bred International, Inc.

StatServer 6.0 goes beyond traditional reporting solutions by including advanced analytics that accurately reveal, quantify and predict opportunities, risks and consequences. The software provides a wide-range of pre-built graphical reports to view predictive analysis of historic data and real-time data.

Insightful also offers specialized models for analyzing data including Customer Behavior Modeling, Six Sigma® quality analysis, sequential trial design, spatial statistics, portfolio optimization and churn analysis, via consulting services. Insightful helps Fortune 1000 customers build Web-based business analytic systems using the StatServer platform delivering information about products, operations and customers – the basis of business intelligence.

"StatServer helps customers analyze data to find new opportunities to cut costs, improve efficiency and increase revenue. The value of StatServer 6.0 is based on the delivery of timely information and accurate predictions to decision-makers enterprise-wide," said Peter Hallett, vice president of marketing and business development of Insightful Corporation. "StatServer 6.0 reflects our ongoing commitment to make it easier to take advantage of sophisticated analytics via a simple Web browser. By simplifying access to mission-critical data and predictive analysis, we help our clients achieve information superiority."

Non-technical users can access and apply analytical techniques to essential corporate data using a familiar Web or Excel-based environment. StatServer 6.0 is a warehouse-independent platform that integrates with any ODBC-compliant database or data warehouse.

• Enhanced Performance and Large Data Set Analysis. StatServer delivers significant performance and scalability gains, allowing customers to process larger data sets faster.

• New S-PLUS Computational Engine. The latest release of S-PLUS provides enhanced graphics, leading-edge statistical methods and superior performance. StatServer 6.0 uses the lastest version of the S language — the de facto standard among developers of high-end analytical applications — making it easy to develop new methods, customize existing applications and integrate with data feeds or Web-based applications.
• Enhanced Web Tools. New "wizard-driven" setup provides easy administration for analytics publishing and information access up, down and across the enterprise.
