Construction site documentation platform with helmet-mounted 360 cameras; automatic floor plan georeferencing for complete project photo records competing with Matterport at Turner and Skanska.
About
OpenSpace is a construction documentation and site monitoring platform that uses 360-degree cameras to automatically capture complete visual records of construction progress — enabling general contractors, owners, and project teams to document site conditions, track construction against design models, and resolve disputes with comprehensive photographic evidence collected by walking the site with a helmet-mounted camera. Founded in 2017 by Jeevan Kalanithi and Alan Teuer in San Francisco, OpenSpace has raised approximately $100 million and serves construction projects at major developers and general contractors including Turner Construction, Skanska, and Mortenson.\n\nOpenSpace's technology consists of a 360-degree camera mounted on a helmet that workers carry as they walk the site — the system automatically georeferences photos to the building's floor plan and creates a timestamped, navigable virtual walkthrough of the entire project site. Project teams can compare current conditions to earlier captures (identifying progress, change orders, or potential deficiencies), link photos to specific plan locations for RFI and issue documentation, and navigate the complete site history from any browser or mobile device.\n\nIn 2025, OpenSpace competes in the construction site documentation market against Matterport (3D scanning), Procore Observations, and Autodesk Construction Cloud Docs for visual documentation and progress tracking. The construction documentation market has significant ROI for projects — a 360-degree photographic record that resolves a single change order dispute or warranty claim can pay for years of platform subscription. OpenSpace's AI layer analyzes captures to automatically detect construction progress compared to the design model, flagging potential deficiencies before they become expensive corrections. The 2025 strategy focuses on AI-powered progress analytics (automated schedule delay risk identification), expanding drone capture integration for exterior documentation, and growing in European construction markets.
