Who it's for

Nigerian and pan-African retail investors (mostly salaried professionals, traders, diaspora) who hold stocks, crypto, or mutual funds and need one dashboard to see it all

How to build it

1. Build a clean web dashboard that connects to free market data APIs (Alpha Vantage, CoinGecko) and Nigerian broker APIs (where available) to auto-pull holdings 2. Add portfolio math: real-time P&L, allocation %, performance vs benchmark (e.g., NGX All-Share), cost-basis tracking 3. Implement push alerts for price triggers and rebalance reminders 4. Create a simple watchlist and comparison tool so users can research before buying 5. Launch with manual portfolio entry (copy-paste trades or upload CSVs) first, then add broker integrations after proving demand

Your edge as a builder from anywhere

Nigerian investors are underserved by portfolio tools—most use spreadsheets or nothing. You can build for naira-earning, dollar-holding diaspora AND local traders simultaneously. Free market data APIs mean zero licensing friction. Launch subscription at ₦2,500–₦5,000/month (or $10–20 USD tier) before competitors target Africa; existing global players haven't localized for NGX, crypto volumes here,
