The picture to the right just about sums up how the HGGC and Serena teams and I were feeling right after we announced the ownership change at Serena Software – sheer excitement for what’s to come.  As you may have read earlier in the week in a press release, private equity firm HGGC and I have partnered to acquire Serena.  The deal brings me full circle.

I founded Serena Consulting in 1980 with the express purpose of being a contract programmer at Bank of America in San Francisco.  It was just me.  I had no large aspirations other than making a living but then I got the urge to enhance this little utility I had written previously to compare files.  I found that many wanted to use it.  That was the kernel of knowledge I needed to take the idea of writing software for the masses.  That utility was Comparex and it funded the company, renamed Serena Software, for hiring people and developing other products.  We did NOT need venture capital.

We took the company public in 1999 and Silver Lake Partners took us private in 2006.  Now that I have the opportunity to buy the company back with the assistance of HGGC, I am thrilled to play a larger role in the company strategy.  Our CEO, Greg Hughes, has streamlined the company to put our expenses in line with revenue.  We are now positioned to focus on the people and products that will put us into growth mode over the coming years.  HGGC is just down Highway 101 from us.  I have high hopes this will be a win-win situation for both companies.  Below is a picture of the HGGC and Serena management teams.

A product I originally created in 1980 celebrates its 30th anniversary today. Comparex remains the most powerful tool on the market for comparing data, text and directory files for the mainframe. With thousands of licenses in production at large sites around the world, Comparex is quite simply the best solution for mainframe data comparison, making it the comparison ‘tool of choice’ for discovering errors, increasing productivity, reducing development costs and shortening deployment times for mainframe development teams. As the creator of Comparex, it thrills me that not only do customers continue to depend on it but that the company I founded continues to add new features for modern workloads.


That is because customer satisfaction has always been our primary goal at Serena. I think that focus is why brand-name companies such as AT&T and GE have used Comparex for 25 years or more. As we begin our fourth decade in business, our plans include continuing to modernize and enhance our mainframe solutions, and maintaining the company’s reputation of excellence in the industry.

To commemorate Comparex’s 30th anniversary, Serena is rolling out a major new release of Comparex. Customers can expect to enjoy a new DB2 ISPF interface to enhance ease of use, an enhanced REXX interface, support for UNIX file systems, and UNICODE support.
