Who it's for
Solo or 2-person team with access to VoIP infrastructure or API partners; target: Nigerians calling family abroad, African migrants, small SMEs doing cross-border business.
How to build it
1. Negotiate rates with a VoIP termination provider (Twilio, Bandwidth, or local African VoIP wholesalers) to lock in low per-minute costs for top call routes (US, UK, Canada, Europe).
2. Build a stripped web app (login, top-up credit via Paystack/Flutterwave, dial keypad, call history) and a mobile web version; no native app needed at launch.
3. Undercut market rates by 30–50% on top routes; advertise via WhatsApp groups, Facebook, and YouTube targeting diaspora communities—emphasize "family calls for ₦50/min to USA" vs competitors at ₦150+.
4. Start with a soft launch to 500 users (friends, family, online communities); track churn and add basic retention features (loyalty credit bonuses after 5 calls, referral rewards worth 10% of spend).
5. Lock in supplier contracts before scaling; build a simple admin dashboard to track call volumes, revenue, and margins per route.
