AspenTech®: Over 40 Years of Innovation

From the 1980s to today, our transformative solutions help thousands of global customers meet operational and sustainability goals.

AspenTech formed from the Advanced System for Process Engineering (ASPEN) Project — joint research between the Massachusetts Institute of Technology (MIT) and United States Department of Energy.

The team explored technical innovations in response to the 1970's energy crisis. They worked to develop the chemical industry’s first computer-based modeling and simulation technology.

The innovations developed in those initial days had a transformative impact, providing the foundation for decades of industrial optimization advancements.

Today, more than 40 years later, AspenTech is over 3700 employees strong with more than 60 locations worldwide. We continue to maintain a "Customer First" mindset and focus on helping our customers deploy, adopt and use our solutions successfully.

While we accelerate digital transformation and optimize assets to run safer, greener, longer and faster, we strive to ensure our customers achieve and continuously grow the value from our industrial solutions.
