Step 1 'AI software selloff is an opportunity' — Goldman Sachs
→
Step 2 Barriers for individual investors in their 50s accessing institutional reports
→
Step 3 Inability to apply institutional investment opinions to personal portfolios

Problem

Individual investors in their 50s see news like 'Goldman Sachs says AI software selloff is an opportunity' and want to buy, but the original reports are in English and written for institutional investors, making them hard for individuals to act on. Critical execution details are missing: which stocks to buy at what price, how to allocate given their portfolio size, and when to exchange KRW to USD. They end up investing on gut feeling.

Solution

On the web, users enter a link to an institutional report or a keyword, and the service summarizes key investment opinions in Korean and generates a 'retail investor action checklist.' Inputting one's investment capital and current holdings enables portfolio rebalancing simulations, exchange rate impact calculations, and net return scenarios including fees.

Target: Ages 50-60, 1+ years of overseas stock/ETF investing experience, able to use brokerage mobile trading apps, investment capital of 10-100 million KRW (~$7,500-$75,000)
Revenue Model: 3 free Report translations/month; unlimited translations + portfolio simulation at 9,900 KRW/month (~$7.50)
Ecosystem Role: Consumer
MVP Estimate: 2_weeks
