ROI Calculation Logic

Assuming a 10% reduction in post-stroke rehabilitation duration. With an average rehabilitation cost of ~$1,650/month (AI est.) per patient, applying this to 100 patients annually could result in a healthcare cost reduction of (~$1,650/month × 1 month saved) × 100 patients = ~$165K/year (AI est.). This directly improves healthcare facility profitability and reduces patient burden.

Speed to Market
6× faster than in-house development
