Commercial cleaning for premium offices — boring, sticky, recurring. €15–25/hour

Real, recurring €90M+ Prague market — but it's one of the most crowded red oceans in the city (~5,300 cleaning firms), and you're entering with zero contacts, no differentiator, and a 2-week timeline that the 3–9 month corporate procurement cycle will eat alive.

Win 3 reference accounts via free overnight "white-glove" trial cleans pitched directly to Prague office managers on LinkedIn — but kill the 2-week, €3–8k fantasy: your real first win is a small paid pilot in week 3–4.

Set up a Czech s.r.o. with a free-trade cleaning license in Prague — but your real problem isn't legal, it's that the 33.8% employer payroll load and €10k budget quietly kill the "30% margin" math.

The unit economics work (~38% gross margin) and breakeven is ~Month 6 — but the real enemy is working-capital timing, not the €10k startup bill, and the whole model hinges on a sales motion this founder hasn't started.

Win on accountability, not "premium": English-speaking account management + photo-proof reliability is the only defensible wedge into Prague's A-class offices — and the €3–8k/month math only works above ~1,500 m² contracts.

Prague's premium-office cleaning lane is crowded with cheap micro-operators (~€12/hr) and faceless enterprise FM giants — the open lane is an English-first, procurement-ready, ESG-reporting boutique, but the real battle is hiring cleaners, not winning clients.
