Wanjiru Kamau grew up watching her father work as a mechanic in Nairobi's Gikomba market. She learned early: fixing things for money is honest work. When smartphones arrived, she taught herself to fix them from YouTube and a repair manual she found in River Road.
For four years, she worked from a 6x6 ft stall in Ngara, earning KSh 800–KSh 1,500 per job with no receipts, no tracking, and no idea what she actually earned each month.
The Decision to Go Professional
In 2024, Wanjiru moved to a proper shop in Westlands with KSh 220,000 in savings. Her goal was simple: be the shop that corporate Nairobi trusted with their expensive devices.
She opened with RepairCoreX on the free plan.
"In Ngara, I was competing on price," she says. "In Westlands, I wanted to compete on quality and trust. But quality alone is not enough — you need a system to show customers you are professional."
The First Six Months
Month 1: KSh 380,000 revenue. Month 2: KSh 610,000. Month 3: KSh 840,000.
The WhatsApp notification feature became her biggest differentiator. Westlands customers — bankers, tech workers, consultants — were accustomed to professional service in every part of their lives. When they dropped a phone and received a WhatsApp status update without having to call, they were genuinely impressed.
"That one feature earned me more referrals than anything else," she says. "People shared it in their work WhatsApp groups."
A Corporate Breakthrough
At month 5, a Westlands-based law firm brought in 12 phones after one of their partners recommended Wanjiru. She handled the account professionally through RepairCoreX: every repair ticketed, invoiced, tracked. The firm's office manager now sends all staff phones to Wanjiru.
This corporate account adds KSh 300,000–KSh 500,000 to her monthly revenue.
Her Life in 2026
Wanjiru earns KSh 1.2 million per month. She employs a technician and a front-desk manager. She drives a good car and has begun building a house outside Nairobi.
"M-Pesa made Kenyans the most mobile-money-savvy people in the world," she says. "RepairCoreX gave my business the same professionalism for repair management."
