Problem

With KakaoBank launching AI-generated invitations, AI design services embedded in financial apps are expanding. However, the default templates are generic and lack specialized designs for specific events (first birthday parties, grand openings, church events, etc.). Small wedding/event businesses (1-5 people) want to offer differentiated invitations but face outsourcing costs of 50,000-150,000 KRW (~$37-$112) per design and lack AI prompt-writing skills, wasting 2-3 hours per attempt.

Solution

Operates a Marketplace for specialized AI invitation prompt templates by event type (first birthday, grand opening, religious events, 60th birthday celebration, etc.). Designers register prompt + style guide bundles, enabling non-experts to generate high-quality invitations instantly by simply entering text. Includes preview and real-time editing features.

Target: Owners of 1-5 person wedding/event planning businesses and Freelancer event planners
Revenue Model: Marketplace transaction fee of 30% per sale (template prices 3,000-15,000 KRW / ~$2.25-$11.25). Premium designer certification at 29,000 KRW (~$22)/month
Ecosystem Role: Supplier
MVP Estimate: 2_weeks
