What Mostardi Platt does
Mostardi Platt is a US-based, independent environmental services firm founded in 1976 and headquartered in Elmhurst, Illinois. The company delivers air emissions testing, continuous and predictive emissions monitoring (CEMS/PEMS), air permitting and modeling, water and wastewater compliance, site assessment and remediation, EHS consulting, and occupational health and safety services to industrial and commercial clients nationwide. It operates from 11 office locations across the United States and has executed projects in more than 45 states plus Canada and Puerto Rico, with primary demand from power generation, manufacturing (cement, steel, glass, food processing), real estate development, and increasingly data center operators.
Underlying capability is built on EPA Reference Method accreditations (Methods 1-5, 17, 25, 25A, 3A, 6C, 7E, 10, 30B) and a fleet of mobile laboratories that perform on-site source testing and ambient monitoring. The firm employs Board Certified Environmental Engineers, licensed Professional Engineers and Geologists, and QSTI-certified staff. Its proprietary technology asset is CMP (Compliance Management Process), a cloud-based EHS compliance management platform that schedules tasks, assigns responsibility, and tracks site-specific compliance performance.
Revenue is generated through project-based professional services contracts, ongoing CEMS/PEMS managed-service retainers, and CMP software subscriptions, sold predominantly via direct enterprise field sales supported by regional office coverage and a self-serve CMP portal. The firm became a portfolio company of Incline Equity Partners in January 2025 and acquired DSG Solutions in November 2025 to extend CEMS/DAHS expertise and add Massachusetts and Washington offices. Customer segments are horizontal across 10+ regulated industries, with no individual customer concentration disclosed.
