ROI Calculation Logic

In medical and research institutions, conventional biofilm observation involves 4 hours of clearing and ~$15 (AI est.) in reagent costs per instance. This technology reduces processing time to 1 hour and reagent cost to ~$5 (AI est.). For a facility conducting 200 observations annually, the estimated saving is (3 hours saved × ~$35/hour (AI est.) + ~$5 saved (AI est.)) × 200 instances = ~$22K/year (AI est.). This translates to ~$20K/year per facility.

Speed to Market
6× faster than in-house development
This technology has a proven track record of prior licensing, demonstrating its effectiveness. Adopting companies could aim for commercialization in as little as 6 months. This represents approximately 2.5 years faster than developing a similar solution in-house.
