Derivation Chain

Step 1 Incheon United K League opening
→
Step 2 Desire for direct sports participation among 50s
→
Step 3 Lack of information on local senior sports clubs
→
Step 4 Integrated board for senior league match schedules and team recruitment

Problem

People in their 50s-60s want to participate in club sports like soccer, badminton, tennis, and table tennis, but information about local senior leagues and clubs is fragmented across KakaoTalk group chats and online cafes. Newcomers cannot find out which teams exist, whether skill levels match, or membership fees, creating high entry barriers. Existing teams also struggle weekly to find substitute players when short on members.

Solution

On the web, users select region/sport/skill level to see a list of local senior clubs and leagues. Display each team's activity frequency, average age, membership fee, and recruitment status. Emergency substitute player recruitment board. Match result records and season statistics.

Target: Ages 48-62, office workers or retirees seeking weekend sports activities, looking for clubs within 10km of residence.
Revenue Model: Free bulletin board. Premium team page (team logo, match schedule management, membership fee collection integration) at 9,900 KRW/month per team (approx. $7.40). Local sports equipment advertising.
Ecosystem Role: Infrastructure
MVP Estimate: 2_weeks
