Portfolio Diversification Assistant

Investors buying single ETFs (like VTI, QQQ, SOXL) want to understand diversification without hiring an advisor. Create a tool that analyzes portfolio overlap, suggests diversification strategies, and explains what they actually own. Target users: beginner investors, retail traders.

Retail investing has exploded since 2020 and a meaningful segment of that cohort now holds a handful of ETFs without understanding the underlying exposure — tools like ETF Research Center and Portfolio Visualizer exist but are clunky, upsell-averse, and not built for mobile-first beginners who discovered investing through Reddit. Portfolio Visualizer is the closest substitute and it's genuinely good, which is the core problem: the free tier covers most of what a beginner needs, making it hard to charge. The $1k–5k/mo revenue band is plausible only if you find a tight acquisition channel like a specific subreddit or newsletter, because conversion from free to paid will be brutal when alternatives are free. The most likely failure mode is that beginner investors don't pay for financial analysis tools — they want reassurance, not rigor, and they'll get that from a YouTube video instead of a $9/mo subscription.
