Derivation Chain

Step 1 Experience-based reemployment matching
→
Step 2 After Senior expert matching: 'don't want full-time, want 2-3 days/week part-time'
→
Step 3 Existing job sites lack a triple filter for 'part-time + professional + Senior'

Problem

Retired professionals ages 55-63 seeking part-time specialist work 2-3 days per week, 4-6 hours per day (quality auditing, safety inspections, accounting advisory, Patent review, etc.) find that searching 'part-time' on job sites like WorkNet or Saramin returns only manual labor positions (convenience stores, delivery). The category 'Senior professional part-time' simply doesn't exist, causing 3-6 months wasted searching or giving up entirely on finding work matching their expertise.

Solution

Retired professionals register their field of expertise, desired work frequency (1-3 days/week), region, and desired compensation to be matched with companies posting 'senior professional part-time' needs. Companies are provided a simple form to post needs like 'quality management expert needed 2 days/week.'

Target: Ages 55-63, retired from large or mid-size corporations, 20+ years experience in a specific field, not seeking full-time reemployment but wanting 2-3 days/week of professional activity
Revenue Model: Profile registration free, 10% commission on first month's compensation upon successful match, Enterprise Premium search at 49,000 won (~$37) monthly
Ecosystem Role: Infrastructure
MVP Estimate: 2_weeks
