KARADANOTE,INC.

Karadanote operates a Family Data Platform business targeting families—primarily pregnant women and mothers with young children—through a suite of mobile apps (e.g., 'Jintsuu Kitakamo' for contraction timing, 'Jyunyu Note' for breastfeeding tracking, 'Step Rinyushoku' for weaning food management) and web media. The company monetizes its proprietary family database via Life Event Marketing, matching users with relevant products and services (insurance, food delivery, education, housing) at key life-stage moments, while also offering insurance agency services ('Kazoku no Hoken') and home-related services ('Kazoku no Ouchi'). A third segment, Family Partnership, leverages accumulated marketing know-how to provide DX and marketing support to large enterprises serving the family-life ecosystem.
