About Us
We've been creating solutions for complex projects since 1994
Our Story
While supporting the International Space Station program, our founder, Gary Arnold, recognized gaps in the current scheduling process and identified opportunties to improve workflows and reporting that customers required. Gary taught himself how to build macros in Microsoft applications othat automated complex analyses and reporting. Those solutions became the foundation of what is now SSI Tools.
As SSI grew, customers needed more than software. They wanted experienced schedulers to support critical programs and expert guidance on project scheduling, Microsoft Project, SSI Tools, and Earned Value Management (EVM). That demand led us to create our Training and Talent divisions, making SSI a true one-stop shop for project scheduling.
Today, more than 30 years later, SSI remains a family-owned business dedicated to helping organizations plan smarter, execute better, and deliver successful projects.
We proudly support 10,000+ end users and hundreds of organizations across aerospace & defense, government, construction, healthcare, manufacturing, and other project-driven industries.
Whether through our Tools, Training, or Talent, our mission remains the same: to provide practical solutions, trusted expertise, and exceptional customer experiences that help our customers succeed.
