The Opportunity

Problem

Rising mobile money transaction fees and strict biometric/SIM registration rules are forcing Ugandan users to abandon secondary wallets, resulting in 22 million accounts going inactive.

Solution

WalletKeep predicts exactly when each of your mobile money accounts will be flagged as inactive under biometric rules and gives you the cheapest possible micro-action to keep them healthy. It consolidates all wallets into one health dashboard with one-tap maintenance USSDs and tracks long-term compliance cost.

Target Audience

Ugandan consumers and small businesses previously maintaining 2+ mobile money wallets across networks for cost optimization and convenience

Differentiator

Predictive inactivity modeling based on each network's exact deactivation algorithms (reverse-engineered from public data and user patterns) β€” the only proactive wallet fitness coach.

Weakness

No predictive model or cost optimization

Our Advantage

🏰 Moat Strategy

Longitudinal dataset of wallet activity patterns across thousands of users creates increasingly accurate predictive models that competitors cannot replicate quickly.

⏰ Why Now?

The government’s aggressive biometric enforcement campaign in 2024 has suddenly made the 22 million dormant account problem urgent for millions of users who previously ignored it.
