Washington DC, USA and Cheltenham, UK – 10th November 2009. Artisan® Software Tools, the world’s largest independent supplier of industrial-grade, collaborative modeling tools for complex, mission and safety-critical embedded systems and software, has acquired Extessy, a leading supplier of development tools and services for system requirements, co-simulation, integration and test, based in Wolfsburg, Germany. Artisan’s acquisition of Extessy closely follows its acquisition last month of Brass Bullet, a leading UK systems engineering consultancy.“This is a significant next step in our ‘complex systems tools market’ consolidation program,” said James B. Gambrell, President and CEO of Artisan Software Tools. “Extessy’s offerings, vertical markets and German reach complement our existing organization and align precisely with our business plans. The real benefit of our joining together with Extessy is not just the scale it gives us, but that our joint offerings work together to help our customers Work as One. No matter how large we grow, we will remain independent-minded and flexible, positioning us particularly well for future growth.”Extessy was founded in 2000 as a provider of software tools and consulting services for embedded system development, deriving the bulk of its business from the German automotive industry. The combined companies will significantly expand Artisan’s operations in Germany. All of the Extessy team will join Artisan, extending Artisan’s knowledge within the key automotive industry, bolstering its professional services capability and extending its global reach. As a direct result, Artisan will be moving its German headquarters from Munich to Extessy’s Wolfsburg offices, while still retaining a regional presence in Munich.“I am extremely excited that Extessy has joined with Artisan Software Tools,” commented Bill Esler, CEO of Extessy AG. “Artisan is a highly successful and fast-growing company with an enviable reputation for providing robust model-based development tools for complex systems development. Extessy will add greatly to the solutions and services Artisan is able to offer to its customers as well as considerably expand the opportunity to continue to grow its market share.”“We are pleased to see Artisan acquire Extessy and commit to the ongoing enhancement of its products and services,” said Theodor Staneff, Manager Product Development and System Support Control and Command Technology of Deutsche Bahn, Munich, Germany. “As a long-term Artisan and Extessy customer, we have been continually impressed by their professionalism and service quality. They appear to have bucked the trend, showing considerable growth during the economic downturn. This move is testament to the dedication and expertise of the Artisan and Extessy management teams and staff.”The merger combines Extessy’s operating business including all products and underlying intellectual property, professional services and expertise with Artisan’s existing German operations. The product portfolio includes the EXERPT requirements interchange and management platform based on the RIF Requirements Interchange Format, the EXITE co-simulation platform and EXACT automated test and validation platform. The sizeable professional services practice focuses on system engineering process consulting, tool customization, training and product support.“Combining Extessy with Artisan is a further step in our ‘whole product’ growth strategy to provide system engineers and enterprise architects across a broad range of industries with a comprehensive range of development solutions and services,” said Hedley Apperly, VP Marketing of Artisan Software Tools. “Extessy’s tools and services perfectly complement our existing model-based solutions for mission, safety and life-critical complex systems development, adding all-important capabilities in terms of system requirements interchange and management, co-simulation and test automation.”About Extessy
