- Purpose and Background of the Fundraising (Challenges Medmain Aims to Address)
The funds raised will be used to further enhance the development of our product “PidPort,” invest in infrastructure for digitalization, strengthen our sales organization, apply for regulatory approval of our pathology AI, and build a foundation for international expansion.
With the global increase in cancer diagnoses, the number of pathology examinations has also risen significantly, leading to a chronic shortage of personnel and placing a heavy workload on medical institutions. Traditionally, pathology diagnoses have long relied on physical glass slides, but at Medmain, we have been supporting medical institutions through the provision of digital services and our platform, “PidPort.”
PidPort is currently used by many clients in a wide range of settings, including remote diagnostic support and consultations between medical institutions, multi-facility conferences, academic conferences, educational use in lectures and training sessions, as well as research and quality control at universities and corporations.
Moving forward, we will continue to enhance functionality and strengthen integration with surrounding systems to further improve service convenience. At the same time, we are committed to expanding support and value delivery to more medical sites, and to strengthening our organizational structure in preparation for global expansion.
