Cumulus Forges Plex Powerhouse, Merging with Revolution Group's Practice

TROY, Mich. – May 01, 2026 – In a significant move set to reshape the smart manufacturing landscape, Cumulus Consulting today announced that the Plex practice of Revolution Group will join its operations. The integration forges what is now positioned as the market's leading and largest dedicated partner for the Plex by Rockwell Automation Smart Manufacturing Platform, promising expanded capacity and deeper expertise for manufacturers across North America.

This strategic combination unites two of the most decorated and experienced teams within the Plex ecosystem, creating a single entity with decades of deployment experience. The move signals a new level of consolidation and specialization in a rapidly evolving industrial technology sector.

A New Leader in the Plex Ecosystem

The claim of market leadership is not unfounded. The new, unified team represents a powerhouse of specialized knowledge. Cumulus Consulting, already a dominant force, was named the 2024 Plex Partner of the Year by Rockwell Automation. Similarly, Revolution Group's Plex practice earned the same prestigious award in 2021, highlighting a consistent track record of excellence from both organizations. By bringing these two award-winning groups under one roof, Cumulus aims to create an unparalleled resource for manufacturers.

"This is a partnership built to last," said David Chidsey, President of Cumulus. "Revolution Group's Plex team has earned the trust of their customers the same way we have — by showing up, doing the work and delivering outcomes that hold up year after year."

The integration is more than just an increase in headcount; it's a strategic deepening of the talent pool. The combined firm now boasts a formidable bench of senior Plex consultants and architects, significantly boosting its ability to take on large, complex implementations. Chidsey emphasized the immediate impact: "Bringing these two teams together means more depth, more talent and more capacity for the manufacturers who depend on Plex to run their businesses."

What This Means for Manufacturers

For current and prospective clients, the company is stressing continuity and enhanced value. The primary goal is to leverage the combined strength to improve service delivery without disrupting ongoing projects. Cumulus has assured customers that existing project leads and account contacts will remain in place, ensuring a seamless transition.

The real benefit, according to the new leadership, lies in the long-term vision. "Customers choose Plex because they're investing for the long term, and they deserve a partner who is committed to that journey," Chidsey noted.

This sentiment is echoed by Pat Welsh, the former Plex Practice Director at Revolution Group, who now steps into the role of Vice President of Sales at Cumulus. Welsh’s transition underscores the integration of leadership and a shared philosophy centered on durable client relationships.

"Our Plex practice has always been about long-term partnerships — relationships built to last, projects that deliver, and customers we serve for years," said Welsh. "Cumulus shares that conviction. Together, we offer customers the deepest bench of Plex expertise in the market while keeping the personal, accountable approach that our customers value most."

The expanded team will serve a wider array of manufacturing sectors, including automotive, food and beverage, aerospace and defense, high-tech electronics, industrial manufacturing, plastics, and metal fabrication. This broader industry footprint allows for cross-pollination of best practices and solutions tailored to specific vertical challenges.

Consolidation in a Booming Industry 4.0 Market

This integration doesn't exist in a vacuum. It reflects a significant trend within the broader Industry 4.0 landscape: the need for larger, more capable service providers to manage the complexities of digital transformation. The global market for Manufacturing Execution Systems (MES), a core component of the Plex platform, is projected to surge, reaching over $42 billion by 2033. This growth is driven by manufacturers' urgent need for real-time data, improved efficiency, and connected factory floors.

The strategic importance of the Plex platform itself was solidified when Rockwell Automation acquired Plex Systems in 2021 for a staggering $2.22 billion. The acquisition was a cornerstone of Rockwell's strategy to build out its "Connected Enterprise" vision, combining its industrial automation strengths with Plex's cloud-native smart manufacturing capabilities.

For Rockwell, a robust and highly competent partner ecosystem is critical to deploying these solutions at scale. The consolidation of two top partners into a single, more powerful entity like Cumulus aligns perfectly with this strategy. It ensures that as Plex adoption grows, there is a premier integration partner with the capacity and skill to handle complex, enterprise-level projects and provide sustained support.

Redefining the Competitive Landscape

By combining forces, Cumulus and Revolution Group's former Plex practice have effectively raised the bar for competitors in the Plex integration space. The new entity's size, combined experience, and official accolades from Rockwell Automation create a formidable competitive advantage. This move could put pressure on smaller, independent integrators who may struggle to match the depth of resources and breadth of services now offered by Cumulus.

The new organization is positioned as a one-stop-shop for everything Plex, from initial implementation and custom development to long-term support and strategic consulting. This comprehensive offering is a powerful draw for manufacturers who prefer to rely on a single, deeply knowledgeable partner for their mission-critical ERP and MES systems.

Ultimately, the success of this integration will be measured by its ability to deliver on its promises of enhanced value and unwavering support. The leadership's shared focus on creating a practice with the "bench, experience and cultural fit to support customers for the long run" suggests a clear understanding of the stakes. For manufacturers navigating the complexities of modern production, having a strong, stable, and deeply experienced technology partner is not just an advantage—it is an absolute necessity.
