ROI Calculation Logic

Assuming a company performs 1 million micro-sample analyses annually, with a conventional re-testing rate of 5% (costing ~$2.00/test, AI est.) due to poor mixing. This technology could reduce the re-testing rate to 1%. The direct savings are (5% - 1%) × 1,000,000 tests × $2.00/test = ~$80,000 (AI est.) annually. Including yield improvements in manufacturing and accelerated development, total cost reductions could reach ~$200K (AI est.) per year.

Speed to Market
