Problem

When office workers retire, the comprehensive health checkup (worth 800,000-1,500,000 KRW, approx. $600-$1,125) provided annually by the company disappears, replaced by the National Health Checkup (once every 2 years, basic items only). People in their late 50s to 60s are at high risk for major diseases such as cancer, cardiovascular disease, and diabetes, but there is no way to determine which additional checkup items are needed or to compare prices for the same items across hospitals, which can vary 2-3 times. This leads to spending on unnecessary items or missing necessary ones, losing opportunities for early detection.

Solution

A web service that recommends checkup items for the current year based on medical guidelines and compares prices at nearby hospitals after users input age, gender, family history, and past checkup abnormalities. Key features: (1) classification of essential/recommended/optional checkup items based on risk factors, (2) price comparison table for checkup centers in the region by item, (3) optimal checkup combination recommendations by budget (300,000/500,000/1,000,000 KRW, approx. $225/$375/$750). Differentiation: evidence-based item recommendations rather than hospital marketing, plus price transparency.

Target: Aged 58-65, recently retired or planning to retire, with family history (cancer, cardiovascular, diabetes, etc.), practical consumers who value cost efficiency in health checkups.
Revenue Model: Basic item recommendation free, hospital price comparison + optimal combination design per transaction 4,900 KRW (approx. $3.68), health checkup center affiliate advertising (CPA).
