DATA FOUNDATION

Our academic data foundation

Universities, professors and researchers, research fields and keywords — harvested directly from KAKEN (KAKENHI), CiNii, researchmap and official university sites, structured and continuously updated. It is the factual ground beneath professor matching, research-plan review and research direction: every judgment rests on this data. The career side lives on the same foundation: industries, roles and company deep reports, every claim evidence-graded.
