What it does: AI-powered construction site monitoring using 360° helmet-mounted cameras. Automatically compares site footage against BIM models to track progress, detect deviations, and generate status reports.
Legacy alternative: Manual site walks, daily reports, Procore photo logs
Key differentiator: Computer vision that matches real site conditions to BIM automatically. No manual tagging or data entry. Real-time progress tracking against the model.
Pricing: Not public (enterprise, typically per-project)
Glazing applicability: Medium — Useful for tracking curtainwall installation progress against BIM, detecting installation errors early.
MVP trial: Request demo with a sample curtainwall BIM model
Watch
What it does: AI-powered pre-construction estimating that automatically detects, measures, compares, and labels features and spaces in architectural plans. One-click takeoff from PDFs.
Legacy alternative: Manual takeoff with PlanSwift, Bluebeam, On-Screen Takeoff
Key differentiator: Pure computer vision — scans plans and identifies components (doors, windows, rooms, walls) without manual input. $299/mo flat rate, no per-project fees.
Pricing: $299/month
Glazing applicability: High — Automatically detects window/door openings, measures glass areas, generates quantity reports.
MVP trial: 14-day free trial, upload a set of glazing shop drawings

What it does: AI-powered quick commerce platform for building materials (plywood, paint, electricals, hardware, plumbing). 30-minute delivery from local dark stores. Raised $5.5M seed from Accel, Fireside, Lightspeed.
Legacy alternative: Traditional building supply ordering, phone calls to suppliers, manual procurement
Key differentiator: Quick commerce model applied to construction — 30-minute delivery, AI-driven inventory and routing.
Pricing: Per-item (marketplace model)
Glazing applicability: Low — Focused on interior finishes and MEP materials. Procurement model is interesting for PGC's hardware and sealant supply chain.
MVP trial: Available in Bengaluru from September 2026
