- **Offsite Prefab Module**: Validation tool for prefabricated components before they leave the warehouse, ensuring accuracy and reducing rework.
- **Quality Control Module**: On-site QA tool that catches errors and clashes early using objective, instant data from the field.

## Market Standing
- **Valuation/Market Cap**: Not publicly available (private company)
- **Key Metric**: Total funding of $37M across 6 rounds; annual revenue estimated at $1.4M (LinkedIn estimate)
- **Notable Investors/Partners**: Not disclosed in public sources, but the company has delivered over $14B in combined project value for clients including global data center developers.

## Competitive Advantages
- **Engineering-Grade AR**: The Atom headset provides 5mm accuracy for BIM holograms, a level of precision unmatched by consumer AR headsets.
- **Real-Time Objective Data**: Replaces subjective progress reports with irrefutable field data, enabling proactive decision-making and de-risking construction lifecycles.
- **Proven ROI**: Documented case studies showing massive cost and time savings (e.g., 408 days saved, $135M+ in rework costs avoided, 10x ROI for a global data center developer).
- **End-to-End Platform**: Combines hardware (AR headset) with software (project controls, quality, prefab) in a single managed service, creating a sticky ecosystem.

## Strategic Focus
- Current priorities and direction for growth: Accelerating delivery of mission-critical projects (especially data centers, pharma, and airports); expanding global footprint (already in 19 countries); deepening portfolio-level intelligence for large developers; continuing to innovate on AR hardware and software integration to eliminate rework and reduce time-to-market for clients.
