The problem was clear: Rwandans were struggling to pay their utility bills. Between remembering USSD codes, missing payments, and having no proof of payment โ€” something had to change.

We built PeSa in just 8 weeks. The app lets users pay REG electricity, WASAC water, and Startimes TV bills in seconds using MTN MoMo or Airtel Money.

Within the first month, over 500 Rwandans had downloaded PeSa and were using it to pay bills. No more dialing codes. No more missed payments.

Users save an average of 15 minutes per bill payment. That's time added back to their day.

This is what we mean by software that solves real problems. That's the Ishvexa approach.
