By | April 14, 2023

We are excited to announce our new 2023 ambassadors! These ambassadors are a group of dedicated individuals who are passionate about promoting and advancing the use of mainframe technology in various industries.

The primary objective of the Ambassadors Program is to inform as many people as possible about how to join the community and advance Open Mainframe. The new ambassadors come from all corners of the world, representing various companies and organizations that use mainframe technology. They were specifically selected for their knowledge, leadership abilities and dedication to the Open Mainframe Project’s mission.

The ambassadors have volunteered to speak, mentor, review materials or presentations and write blogs or contributed articles that showcase Open Mainframe as an umbrella foundation or any of the projects that fall under it.
