What Stone Technologies does

Stone Technologies operates in the industrial automation services sector and is headquartered in Chesterfield, United States. Associated source data indicates a close affiliation with Gray AES, formed in January 2025 through the merger of Gray AE, Gray Solutions, and InLine Engineers to serve as the Professional Services segment of The Gray Family of Companies. The combined entity delivers integrated architecture, engineering, robotics, and automation services to industrial and commercial customers across greenfield builds, expansions, and modernizations, organized into four service pillars: Facility Design, Process & Packaging Engineering, Automation Solutions, and Robotics & Vision.

The service portfolio spans the full project lifecycle — front-end loading and feasibility, EPC turnkey delivery, architectural and detailed design engineering, execution and installation, start-up and commissioning, and ongoing technical support — together with automation and controls, digital transformation and Industry 4.0 implementations, OT cybersecurity for industrial control systems, robotic system integration, machine vision, AMRs/AGVs, and Boston Dynamics Spot deployment. Delivery is executed under a design-build methodology with a single unified team, contrasting with the more common multi-vendor model used in industrial facility projects.

The firm generates revenue through customized, project-based professional services engagements sold via an enterprise field-sales motion to large industrial customers (named engagements include Champion Petfoods in pet food manufacturing and Castle & Key Distillery). Pricing is not publicly disclosed and is negotiated per project. As part of the larger Gray conglomerate spanning Construction, Professional Services, Specialty Equipment, and Real Estate, the entity benefits from cross-segment customer access and bundled delivery opportunities. The firmographic record for Stone Technologies (founded 1996, 51–100 employees) appears to reference a smaller, distinct operating scope from the broader Gray AES conglomerate described in the source data; this mismatch is unresolved and constrains precise sizing.
