Step 3 Need for safe matching with like-minded companions

Problem

Women in their 50s often give up attending Trot concerts or fan meetings because they have no one to go with. Spouses are uninterested, friends' schedules don't align, and returning home alone after evening performances feels unsafe. When seeking companions on ticket transfer cafes, there's a risk of scams or no-shows, causing them to miss out on an average of 3-4 concert opportunities.

Solution

On the web, users select their desired concert and seat grade, and the service matches them with companions from the same region, age group, and preferences. It provides identity-verified profiles, a mutual rating system after the event, and shared transportation options to the venue. Integrated group ticket purchasing ensures adjacent seats.

Target: Women aged 48-58, with a hobby of attending Trot or musical performances, residing in the Seoul metropolitan area, and either single or in households where their spouse has different tastes.

Revenue Model: Basic matching is free; Premium matching (including seat grade and transportation) is 4,900 KRW/month (~$3.70). 3% commission on group ticket purchases.
