Problem

Retirees aged 55-62 who start Solo Entrepreneur online businesses (Naver Smart Store, Class101 courses, blog-based consulting) spend KRW 500K-1M/month (~$375-$750/month) on advertising without knowing whether Naver ads, Instagram ads, or blog SEO best fits their product. Ad Platform UIs are complex, filled with marketer jargon (CPC, ROAS, CTR) designed for 20-30 year olds, creating a steep learning curve. No resource teaches how to run small-budget tests (KRW 50K-100K / ~$38-$75).

Solution

Users select their business type and target customers on a web interface, and receive a step-by-step '7-Day Marketing Experiment Starting at KRW 50K (~$38)' scenario. The tool recommends channels among Naver keyword ads, Instagram boosting, and blog posting. After running small-budget campaigns, users input results (clicks, inquiries, sales) and get clear guidance: 'invest more in this channel' or 'stop this channel.'

Target: Ages 55-62, within 6 months of starting a Solo Entrepreneur online business post-retirement, zero marketing experience, monthly ad budget KRW 100K-300K (~$75-$225)

Revenue Model: First experiment scenario free. Monthly marketing experiment Report + channel recommendations KRW 9,900/month (~$7.50/month). Ad Platform affiliate commissions.
