Collaboration with Seiden Group has played a key role in accelerating the modernization of our IBM systems. Their team has been instrumental in helping my staff understand and evaluate modernization options, and the level of support has been exceptional.

“I can personally vouch for the amazing experience I had with Alan and the team on our PHP RPM setup. You can look at forums and get partial information, but you don’t get the full picture. Involving me in the process, I felt like part of the group and I learned a lot.”

Our busy ecommerce site is running as smooth as can be.”

PHP applications running on IBM i.”

“Alan and the team at Seiden Group have been excellent to work with moving us to Seiden PHP+. The migration was quick and easy with their support and guidance, and we were able to make the move without any disruption to our users. We saw immediate performance improvements. We recommend the Seiden team for all your PHP support needs.”

Larry Amond Director of Application Development –GRAR.com

“We saw a 25% improvement in our application performance after moving from ZS PHP 5.6 to PHP+ 7.4.”

Dick Donohue Iron Road Healthcare

“After a loss of functionality from a vendor’s update, Alan and his team were immediately available to address the issue. They quickly grasped the symptoms, identified the problem, and restored our software to full functionality. I would not hesitate to recommend Seiden Group as a ‘go-to’ for IBM i support.”

Karl Gallmeyer Music Theatre International

“Reaching out to you was definitely the right choice. Now I am confident that I am moving in the right direction with PHP on the IBM.”

Jim LomonacoCo-operative Feed Dealers

“Your group did a great job with PHP migration to RPMs. It was fun, I learned a lot! Please use us as a reference.”

Bob Hughes

“The transition to RPM PHP was virtually seamless. RPM PHP ran side by side with Zend during the transition. Thanks to a utility provided by Seiden Group, we knew exactly which extensions we needed before we even began. Seiden Group quickly built an additional extension for us, long before our goal to go live!”
