AspenTech Celebrates 40 Years of Innovation

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

This year marks 40 years of Aspen Technology!

Since the very beginning, AspenTech has kept our promise to deliver world-class products, solutions and services.

CEO Antonio Pietri shares more on this special occasion.

AspenTech formed from the Advanced System for Process Engineering (ASPEN) Project at MIT.

The team – including Willie Chan, AspenTech’s current Chief Technology Officer – explored technical innovations in response to the 1970s 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, 40 years later, AspenTech is over 1700 employees strong with more than 30 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.
