MySQL AB Secures $19.5 Million Investment Round Led by Benchmark Capital

Additional Investors in Open Source Database Leader Include Index Ventures

SEATTLE, Wash - (June 3, 2003) - MySQL AB, developer of the world’s most popular open source database, announced today the completion of a $19.5 million Series B round of financing to fuel its growth in the mainstream DBMS market. Benchmark Capital, the leading global early stage high-technology venture capital firm based in Menlo Park, Calif., is leading the round. Other investors include Index Ventures, a prominent European venture capital firm headquartered in Geneva, Switzerland. MySQL also announced today that Kevin Harvey, general partner of Benchmark Capital, will join MySQL AB’s board of directors. MySQL AB has headquarters in the United States and in Sweden.

“We chose Benchmark Capital as the lead investor because it has an outstanding track record in building successful companies operating with new business models, such as eBay and Red Hat,” said Mårten Mickos, CEO of MySQL AB. “The DBMS market is at a turning point, as databases become more commoditized and businesses re-evaluate their data management software strategies,” Mickos continued. “MySQL is in a unique position to address today’s database requirements, and with the funds from Benchmark and others, we can ramp up our commercial business while continuing to support the open source community.”

“MySQL AB is a strong ‘second wave’ open source company with a profitable business model, a winning technology that is battle tested by a community of more than 4 million open source advocates, and an established worldwide reach,” said Mr. Harvey. “We believe MySQL AB has significant growth potential, and we look forward to helping it attain a long-term leadership position in the database market.”

MySQL AB develops and markets the MySQL® open source database, a high-performance relational database management system for Web site and business application development and deployment. MySQL AB employs a dual licensing business model, in which the MySQL database is available under the GPL free software/open source license at no cost and also under a non-open source commercial license. MySQL AB’s licensing structure supports its open source user community with a sustainable business model, and this community, in turn, is the engine behind the company’s commercial business.
