Bentley Systems

Bentley Systems is a 40+ year specialist in software for civil engineering, infrastructure, and the built environment — segments where Autodesk has historically been weaker. Founded in 1984 by the Bentley family (Greg, Keith, Barry, Ray, and Scott Bentley), the company remained private for decades before going public on NASDAQ as BSY in 2020.2 billion (FY2024).

The company's flagship platforms include MicroStation (CAD for civil/infrastructure projects), STAAD (one of the most widely used structural analysis tools globally), OpenBuildings (BIM for buildings), OpenRail (rail and transit), OpenRoads (highways), OpenSite (land development), and ProjectWise (engineering content management). Bentley's iTwin platform is the company's strategic AI bet — a cloud-based digital-twin infrastructure that combines BIM data, IoT sensor feeds, and AI-driven analytics to manage assets across their full lifecycle, from design through construction into ongoing operations.

Bentley's 2018 acquisition of Synchro Software brought 4D construction scheduling into the portfolio, and the 2021 acquisitions of E7, Sea-Level Engineering, and Aarcher accelerated its move into resilience analytics, water-systems engineering, and environmental compliance. The company's customers include the world's largest engineering firms (AECOM, Jacobs, WSP, Stantec, Arcadis, Mott MacDonald), national infrastructure agencies (UK National Highways, Singapore LTA, Indian Railways), and major asset operators across rail, utilities, and water. iTwin and the broader Bentley platform are central to most large-scale infrastructure programs in the West and Asia.
