Serkan Demir grew up in Eminönü, surrounded by Istanbul's oldest markets. He learned electronics repair from a workshop behind the Grand Bazaar and spent three years fixing phones for shop owners who paid him ₺5,000 per month — while the shops earned ₺150,000+.
"The money was in the system, not the skill," he says. "I had the skill. I needed the system."
The Investment
In 2023, Serkan opened a shop in Kadıköy — Istanbul's vibrant Asian-side commercial district. Investment: ₺85,000. He signed up for RepairCoreX before he opened the shop doors.
"My goal was to be the repair shop people in Kadıköy talked about. In Istanbul, reputation spreads through mahalle networks — neighborhood WhatsApp groups, building chat apps, coffee shop conversations. One satisfied professional customer in Kadıköy can bring 20 more."
The Difference
Every customer received a digital job ticket on their phone. Every status update came via WhatsApp. Every invoice was itemised and e-fatura compliant.
"Istanbul's educated customers are not surprised by bad service — they expect it," he says. "They are surprised by good service. When something works exactly as promised, they share it."
Within 90 days, Serkan had more than 200 five-star Google reviews.
The Growth
RepairCoreX scaled with each new location — managing all three shops' jobs, inventory, and performance from a single dashboard.
His Life Today
Serkan earns ₺1.0–₺1.2 million monthly across his three shops. He employs 7 people. He is planning a franchise model for other Turkish cities.
"Istanbul has 16 million people and almost no professional repair businesses," he says. "The market is open. If you have skill and a real system, you can build something remarkable here."
The RepairCoreX free plan is where his story started. It can be where yours starts too.
