Careers at Aspen Technology


Aspen Technology’s mission is to enable process industries to optimize engineering, manufacturing, and supply chain operations.

Business segments

Aspen Technology is a provider of software and services for firms in the process industries. The company operates two reportable business segments:

  • Subscription and Software – Offers the licensing of process optimization software and related support services.
  • Services – Offers training and professional services.


Dr. Larry Evans was a professor of Chemical Engineering at MIT. At a certain point he had an observation – the information collected during process design efforts at process industries was never used in the operation of their own facilities. He believed this knowledge should be stored, and that the most efficient way to do so was through a model - a format engineers are comfortable with. In other words, process models should be created so they can be more easily carried out.

In 1981 Evans obtained a grant from the U.S. Department of Energy to build the model. The project was named Aspen Technology and called AspenTech for short. “Aspen“ stood for “Advanced System for Process Engineering“. The result of his team’s efforts was Aspen Plus, a software solution for chemical process modeling. Evans knew that the model would not be used without sufficient promotion, so he obtained private funding to assist with packaging, marketing, support, etc.

The coming decade saw a number of milestones. AspenTech was incorporated as a company in 1981. Later that year the Aspen Plus product was released commercially. In 1984, the firm released Aspen PIMS, the first planning software for refineries, and in 1986 it introduced Aspen DMCplus, an advanced process control product. AspenTech went public in 1994. It now provides a broad slate of solutions for process industries to design, manage, and optimize their business processes.

Benefits at Aspen Technology

Business model of Aspen Technology

Customer Segments

AspenTech has a niche market business model, with a specialized customer segment. Its customer base consists of firms in process industries such as chemicals, energy, construction, and engineering, as well as power, pulp and paper, metals and mining, biofuels, pharmaceuticals, and packaged goods.

Value Proposition

AspenTech offers five primary value propositions: accessibility, convenience, innovation, performance, and brand/status.

The company creates accessibility by offering a comprehensive solution. While most of its competitors provide solutions in one or two main business areas, it offers a set of software programs that address the manufacturing, engineering, and supply chain needs of process manufacturers. Moreover, its portfolio of applications tackles extremely complex and specific end-user and industry challenges, such as production scheduling for petroleum companies and feedstock selection.

The company creates convenience by offering the aspenONE licensing model. The model enables customers to their usage of numerous applications in a suite through the use of tokens (exchangeable units of measurement) licensed in amounts determined by the user. This flexibility allows the customer to use the applications whenever necessary and experiment with different ones to optimally solve their essential business problems. Software usage can also be easily increased.

The company has a history of embracing innovation. It claims that no other technology firm in the field of process manufacturing spends more on research on development as a percentage of revenue. This significant investment has enabled it to produce a number of industry firsts, such as:

  • The first planning software for refineries
  • The first commerically-available model predictive control software
  • The first search algorithms for optimizing polymers scheduling
  • The first Configured Application Product (CAP) in supply chain management

The company has demonstrated strong performance. For some customers, first-year cost reductions following installation of AspenTech’s software have exceeded the solution’s total cost. Benefits experienced by specific clients include the following:

  • Reliance Industries used Aspen Plus to increase production, resulting in $2.4 million in savings
  • Campbell’s used the Aspen Capital Cost Estimator to reduce time for capital decisions by 30%
  • Criterion used Aspen’s planning solutions to improve coverage of customer demand
  • HGA used aspenOne Engineering to reduce time spent sizing relief valves by 50%

The company has established a strong brand as a result of its performance. It bills itself as the top supplier of software that optimizes process manufacturing. It also indicates that it holds #1 or #2 market share positions across all manufacturing, engineering, and supply chain software categories. The company has over 2,100 customers, which include 19 of the 20 largest chemical companies, 20 of the largest petroleum companies, 17 of the top 20 engineering & construction companies, and 15 of the 20 largest pharmaceutical companies. Lastly, it has received many honors, including

two Pharmaceutical Manufacturing Magazine “Innovations 2012” Awards, Boston Strategies International’s Oil and Gas Award for Excellence in Process Optimization (2012), placement on Supply & Demand Chain Executive’s Supply & Demand Chain Executive 100 (2011), and Chemical Processing Magazine’s Readers’ Choice Award nine years in a row.


AspenTech’s main channel is its direct field sales organization. It also utilizes an inside sales team that focuses on clients in the small and medium businesses category, and maintains channel relationships with certain firms that help it reach non-core target markets. The company promotes its offerings through its website, social media pages, user group meetings, webinars, client relationship programs, and attendance of seminars and trade shows.

Customer Relationships

AspenTech’s customer relationship is primarily of a personal assistance nature. The company offers Premier Plus Support, a suite of customer service options featured in license subscription agreements that goes beyond regular Premier Support. It includes the following:

24x7 Customer Care Service – Customers receive around-the-clock access to assistance on non-technical issues, as well as escalation to the Technical Support department for technical issues

Technical Support Advocate Service – Customers receive dedicated Technical Support Advocates (TSAs) who have expertise in their specific installed products and conduct regular check-ins

Faster Response Time and Escalation Time – Quicker response and resolution times than provided through regular customer service (Premier Support); staff must meet these targets 80% of the time

AspenTech also offers the following training options for customers:

Instructor-Led Training – Traditional classroom training, virtual classroom training, and private on-site training (held at customer’s location)

Professional Services – Services that address clients‘ design and operational needs; they include:

  • Solution Implementation – Helps clients derive more value from existing systems and assets
  • Process Consulting – Advises on optimal changes to improve the design of assets
  • Program and Project Management - Facilitates successful solution delivery while reducing risks

Despite this orientation, there is a strong self-service component. The company’s website features a “Resource Library” that includes articles, brochures, data sheets, case studies, eBooks, short presentations, webinars, “getting started” guides, product version comparisons, white papers, and answers to frequently asked questions. There are also eLearning modules featuring videos.
