Problem

When people in their late 50s to early 60s suddenly become single-person households due to children moving out or spousal bereavement, they must simultaneously handle housing downsizing, utility name transfers, national health insurance status changes, and food budget restructuring — without knowing the proper sequence or priorities for visiting each agency. The bigger problem is that for the first 3 months after transition, fixed costs (maintenance fees, health insurance premiums, food expenses) run 30-40% less efficiently per capita compared to when they were a two-person household.

Solution

Users enter their transition reason (independence/divorce/bereavement) along with current housing type and income on the web, and the service generates a 3-phase roadmap: 'administrative tasks within 72 hours → lifestyle changes within 1 week → fixed cost optimization within 1 month.' Each phase includes agency visit sequences, required documents, and estimated time needed. A post-transition monthly fixed cost simulation quantifies the downsizing savings.

Target: Ages 55-65, transitioning (or about to transition) to a solo household within the past year due to children's independence or bereavement, residing in a metropolitan-area apartment
Revenue Model: Basic roadmap: Free. Custom fixed cost optimization simulation + downsizing recommendation Report: 7,900 KRW (~$5.90) Per Transaction.
Ecosystem Role: Infrastructure
