Step 2 License management issues for mid-to-senior technical license holders

Problem

50s technical workers hold multiple essential licenses such as construction safety engineer, electric engineer, and fire equipment engineer, but each has different renewal cycles (3-5 years), continuing education deadlines, and career reporting deadlines. Management agencies are dispersed (HRD Korea, Korea Fire Safety Institute, Korea Electric Association), so missing renewal deadlines leads to license suspension, making them unable to work on site and causing income loss of millions of won. Many 50s technicians miss 1-2 renewal deadlines each year.

Solution

On the web, users input their list of licenses and acquisition dates, and the service manages renewal deadlines, continuing education deadlines, and career reporting deadlines for each license in an integrated calendar. It sends step-by-step alerts (email/KakaoTalk) at D-90, D-30, and D-7, and automatically provides available continuing education schedules and application links at those times.

Target: 48-60 years old, holding 2 or more technical licenses in construction, electrical, fire, or safety fields, currently working on-site as technical professionals.

Revenue Model: Free for up to 3 licenses. Unlimited license management + KakaoTalk alerts + automatic education schedule matching: 2,000 KRW (approx. $1.50) per month. Advertising and partnership fees from continuing education institutions.
