About Lounbréck

Built by people who lived
Luxembourg's compliance problem

We didn't build Lounbréck because it was a market opportunity. We built it because the existing tools kept failing the HR teams managing Luxembourg's cross-border workforce.

Our story

Luxembourg's labor market is unlike anywhere else in the world. 44% of the workforce commutes daily from France, Belgium, and Germany — 231,000 people crossing borders every morning to work in one of Europe's wealthiest countries.

Managing these employees requires navigating three separate bilateral tax treaties, post-2024 WFH thresholds, CCSS social security declarations, and ACD tax class routing — none of which are handled correctly by generic payroll platforms built for domestic employment.

We built Lounbréck to solve that problem with precision. Not a workaround. Not a spreadsheet. A purpose-built compliance layer for Luxembourg SMEs that takes the risk off the HR team's desk and puts it on software that doesn't make mistakes.

The name? Lounbréck — an invented word built around Luxembourg's unique position: a country where national borders are crossed at the speed of a morning commute. We think the accent mark earns itself.

What we believe

⚖️

Compliance without guesswork

Every calculation in Lounbréck is traceable to an official treaty text, ACD ruling, or CCSS directive. We don't estimate. We implement the actual rules.

💶

Per-employee pricing

Flat platform fees punish small teams. We charge per employee — so a 10-person company pays proportionally less than a 200-person company, always.

🔍

Transparency over automation

Automation is great. But you still need to understand what changed and why. Every action Lounbréck takes is visible, auditable, and explainable to your team — and your auditors.

Why Luxembourg

The most complex cross-border labor market in the world

No other country in Europe has Luxembourg's frontalier ratio. Nearly half the workforce lives abroad, meaning Luxembourg employers are simultaneously managing domestic labor law and three international treaty frameworks — for the same job roles, in the same office.

Post-2024, the bilateral WFH agreements with France, Belgium, and Germany introduced hard annual thresholds that trigger tax residency changes. Exceed 29 days working from home in France, and your employee's social security treatment changes. Most HR platforms have no idea this exists.
