Step 3 Weather-based sales risk early alert API for Small Business Owners

Problem

Approximately 300,000 Small Business Owners operating outdoor cafes, food trucks, and mobile shops are directly affected by weather and make business decisions based solely on weather forecasts. When the precipitation probability is 50%, they have no criteria for deciding whether to open. Unnecessary commuting and material preparation result in average daily losses of $112-$225 (~150,000-300,000 KRW), occurring more than 20 days per year.

Solution

A business recommendation alert service combining the Korea Meteorological Administration's ultra-short-term forecast API with historical sales-weather correlation analysis. (1) Ultra-short-term (6-hour) weather risk score based on business location, (2) industry-specific (cafe/food truck/market) business recommendations based on historical data, (3) KakaoTalk alerts sent twice — the evening before and the morning of.

Target: Small Business Owners operating outdoor/mobile shops (food trucks, flea market sellers, outdoor cafes, ages 30-50s)
Revenue Model: SaaS Monthly Subscription at $14/month per shop, Premium (multi-zone alerts) at $29/month. Target ARR of ~$51,300 with 3,000 shops onboarded
Ecosystem Role: Supplier
MVP Estimate: 2_weeks
