Larger system integration firms, more engineers

From 2021 to 2025, the dominance of larger firms in the market has become increasingly apparent. The percentage of companies generating more than $100 million in total gross revenue rose from 12% in 2021 to 24% in 2025. This seems to indicate a competitive environment where scale is a clear advantage for sustained growth. On the other hand, the share of smaller integrators (with up to $25 million in total gross revenue) declined from 60% to 39% over the same period, reflecting a potential consolidation of market influence among larger players.

System integrator revenue increases 86%, 2021-2025

For ranking purposes, “system integration revenue” is defined as revenue derived from automation integration services after deducting the costs of all off-the-shelf products, including hardware, software and equipment. Notably, total system integration revenue has shown a positive year-over-year trend, with the aggregate value increasing by nearly 86% between 2021 and 2025, underscoring the expanding demand for complex integration projects.

The role of engineering talent has been vital in this growth. The average number of automation and control engineers primarily assigned to system integration projects rose from 105 in 2021 to 168 in 2025. This increase suggests a strategic emphasis on enhancing workforce capacity to meet growing project complexities and client expectations.

System integrators need, supply automation engineering skills

The industry also has faced evolving challenges. While the COVID-19 pandemic severely impacted operations in 2022, recent years have seen staffing issues, particularly the recruitment and retention of skilled young engineers, come to the forefront. Rising costs for labor and materials have also been significant concerns for many firms.

To stay competitive, educational and professional development programs have played an essential role. Despite slight declines in participation, strategies such as paid conference attendance and internal mentoring continue to be prioritized, albeit with adjustments due to changing budgetary considerations.

This year’s listing exemplifies the resilience and adaptability demonstrated by top system integrators as they navigate economic fluctuations, workforce changes and technological advancements. The leaders showcased in the 2025 System Integrator Giants listing have embodied the innovation and strategic foresight needed to excel in this dynamic field.
