ROI Calculation Logic

Assuming a 20% reduction in conventional drug development timelines during the exploratory research phase due to improved candidate screening accuracy. If the cost reduction per project from shortened development is estimated at ~$0.7M (AI est.) annually, applying this technology to two projects could yield an annual economic impact of ~$1.5M (AI est.). This contributes to reducing development and clinical trial costs, and generating revenue opportunities through earlier market entry.

Speed to Market
4× faster than in-house development
This technology features a unique device structure combining anaerobic conditions and co-culture, with established basic culture protocols. This allows adopting companies to quickly initiate projects based on existing knowledge and the device, rather than starting R&D from scratch. Even including optimization for specific cell types or drug evaluation systems, it is estimated to shorten development time by approximately 2.5 years compared to in-house development.
