# Stock Alert & Screener Tool

Stock Alert & Screener Tool is a product idea in the fintech category at difficulty 3/5, with strong market demand and an estimated revenue potential of $2k-10k/mo.

## Summary

A lightweight stock monitoring app that alerts users when stocks hit 52-week highs, surge by specific percentages, or match custom criteria. Targets retail investors who want to catch emerging opportunities without complex trading platforms.

## Why this is interesting

Retail investing participation remains structurally higher than pre-2020 levels, and the proliferation of commission-free brokerages has created a large base of self-directed investors who lack institutional-grade screening tools but find Bloomberg Terminal overkill. Finviz is the obvious incumbent here — it's free at the basic tier and deeply entrenched — which means competing on breadth is a losing strategy; the only viable angle is a narrower, cleaner UX with superior mobile alerting. The $2k–$10k/mo revenue band is realistic but tight, achievable through a freemium model with paid alert tiers, though churn will be high because engagement is episodic — users go quiet in flat markets. The biggest risk is that Finviz, TradingView, and brokerage-native alerts (Robinhood, Webull) already cover the core use case well enough that the marginal user never pays for an alternative.
