Miriam Steiner worked in IT operations at a Zurich private bank for 6 years, earning CHF 95,000 per year. Good income by most standards. In Switzerland, it was comfortable but not exceptional — Zurich has some of Europe's highest living costs.
She had been repairing phones and laptops for her bank colleagues and neighbours for 4 years as a favour. A senior banker once offered her CHF 350 for an emergency iPhone screen replacement at 8pm on a Sunday. She did it in an hour. That one repair was more than what an average Swiss worker earns in a day.
"I realised I was performing favours worth CHF 4,000–5,000 per month and not charging for them," she says. "The market was asking me, explicitly, to open a business."
The Investment
In 2024, Miriam opened a shop in Wiedikon — a Zurich neighborhood popular with young professionals, families, and the city's diverse international community. Investment: CHF 32,000.
RepairCoreX was set up before she had a single customer.
"In Switzerland, the first question any serious customer asks is: 'Do you give a Garantie?' The second is: 'Can I have a proper Rechnung?' RepairCoreX answers both questions automatically from the first repair."
Month One
Month 1 revenue: CHF 78,000. For an 8-jobs-per-day average at CHF 310 ticket, this was extremely strong — driven by referrals from her bank connections and the density of professionals in Wiedikon.
"Zürich is a small city where everyone knows everyone in professional circles," she says. "One satisfied banker brings their entire floor within two weeks."
Month by Month
Miriam earns CHF 18,000–CHF 22,000 monthly net.
Her Message
"Zürich zahlt CHF 300+ pro Reparatur," she says. "But the customer has to trust you. RepairCoreX gives you the system to earn that trust immediately — professional tickets, German invoices, warranty documentation. Everything a Swiss customer expects."
"The market is extraordinary. Build your business here."
