ROI Calculation Logic

Assuming a skilled trainer's movement evaluation costs ~$100K/year (AI est.) in sports and rehab facilities. Deploying this technology across 10 locations could yield an annual economic impact of ~$1M (AI est.), combining a 20% reduction in evaluation time (~$20K/year/location, AI est.) and a 5% increase in customer unit price due to improved instruction quality (~$80K/year/location, AI est.).

Speed to Market
4× faster than in-house development
The core algorithm for skin dynamics analysis is already established and theoretically validated. This significantly shortens the development period compared to building similar technology from scratch. Since it relies on generic image input devices and software integration, minimal new hardware development is required, allowing for relatively rapid implementation into existing systems.
