What Environmental & Safety Support does

Environmental & Safety Support Group (ESSG) is a privately held EHS solutions provider founded in 1993 and headquartered in Edmond, Oklahoma. The company operates a platform-plus-modules architecture organized around nine sub-brands: SiteDocs (enterprise safety management software), Safety U (LMS with 330+ training courses), SDS Guru (SDS/GHS management), MoApps (custom mobile EHS apps), Enviro (environmental compliance services), Safety Man (safety consulting), OnSight (EH&S staffing), AudioChecks (mobile occupational health testing), and the 3P Compliance Management System (ISO 9001/14001 framework). The company serves manufacturing, construction, and general businesses across the United States and Canada, with horizontal segmentation and a primarily enterprise field sales go-to-market supplemented by self-serve website demos.

ESSG's technology stack is cloud-based SaaS, with SiteDocs as the central platform handling digital forms, compliance tracking, hazard management, certification tracking, and analytics. The platform claims 53 million signatures collected and 28 million forms submitted, supporting real-time compliance monitoring via mobile apps with offline capability. The SiteDocs Workflow Studio, launched in 2025, adds drag-and-drop workflow automation and integration with 1,350+ third-party applications. The Chemical Inventory Analysis (CIA) software is a proprietary screening engine matching customer chemical inventories against EPA, OSHA, and DHS regulatory lists to produce 26 compliance reports. The company does not provide a public API of its own, but exposes integration endpoints through the workflow layer.

The business model combines recurring SaaS subscription revenue (SiteDocs, Safety U, SDS Guru, MoApps) with professional services revenue spanning environmental management (air permitting, stormwater, SARA reporting), safety consulting (OSHA compliance, incident support), occupational health testing (audiometric, respiratory fit), and EH&S staffing (temp-to-hire, direct placement). Pricing is size-based for software with quantity discounts, while services are quote-based with flexible monthly, quarterly, or upfront payment terms. The company is founder-owned and bootstrapped, led by Owner/CEO Andy DeWitt, with an 11-50 employee headcount and no disclosed external funding. ESSG has not pursued an AI/ML strategy to date — the product set is built on rule-based regulatory mapping and traditional SaaS workflows.
