Stone Technologies, Inc. was founded in 1996 in St. Louis, MO. The goal was to create a premier national systems integration company focused on project delivery in select industries, control and MES technologies. Understanding that it takes an all-star team to deliver premier solutions, the company created a working environment where its employees can have fulfilling professional and personal lives.

Our company specializes in larger, complex, leading edge, solutions to provide bottom line value to its clients by providing industrial automation services, including process control and manufacturing execution system (MES) design, software development and commissioning. Our strategy is to establish long-term relationships with our clients to better understand their businesses and needs.

Today, we have over 80 full-time professionals, specializing in design, development, and implementation. With an average 20 years industry experience, these employees are located in 22 states. Our founders still believe in commitment to our clients; staying personally engaged in those relationships and being actively involved on projects.
