Legal advice: common mistakes scale-ups make when expanding into Europe

Europe represents a massive market opportunity for US scale-ups, but its legal fragmentation is frequently underestimated. The primary error is assuming that a “one-size-fits-all” legal strategy (based on the US experience) will apply across the continent.

Here are the most frequent legal pitfalls encountered by US companies during their European expansion:

1. Underestimating local labor law

The most costly mistake is attempting to apply US at-will employment practices in Europe.

  • Employment contracts: European contracts are highly regulated. In France, for example, non-compete clauses are often valid only if financially compensated, and probation periods are strictly governed by law and collective bargaining agreements.
  • Managing exits: Terminations are heavily regulated and require strong justification and lengthy formal procedures. Ignoring these rules can lead to expensive, drawn-out litigation and substantial severance payments.

2. Confusing Permanent Establishment (PE) with subsidiary

Often, a scale-up begins by hiring a single commercial employee in Europe. If this employee has the authority to conclude contracts on behalf of the US company, this action can inadvertently trigger a Permanent Establishment (PE) in that country.

Consequence: The US company is then deemed to have a local taxable presence and becomes liable for Corporate Income Tax in that jurisdiction, often without having set up the necessary local compliance structures.

3. Non-compliance with data privacy laws (GDPR)

Even if the headquarters is in the US, any subsidiary and any operation processing data belonging to individuals located in the EU must comply with the General Data Protection Regulation (GDPR). GDPR protects natural persons within the EU, regardless of their nationality.

  • Data transfers: The transfer of personal data from European subsidiaries to the US headquarters’ servers must be formalized and secured (often via Standard Contractual Clauses – SCCs).
  • Penalties: Penalties for non-compliance are severe, potentially reaching up to 4% of annual global turnover.

4. Lack of coordination on Intellectual Property (IP)

When a scale-up delegates development tasks to its European subsidiary or hires local developers, the transfer of the created Intellectual Property (IP) must be explicit and formally addressed in the employment or service contracts.

The risk: Without clear and legally sound clauses valid in the local jurisdiction, the US parent company could find itself without complete ownership of the innovations developed in Europe. This lack of clarity can significantly complicate future fundraising, due diligence processes, or M&A transactions.

5. The solution: Adopt a “jurisdiction-specific” approach

To avoid these errors, the best defense is never to make assumptions. From the expansion phase onward, it is essential to consult specialized local experts in each target jurisdiction to validate:

  • The legal structure of employment contracts.
  • The IP assignment mechanisms.
  • The tax thresholds that trigger a permanent establishment.
  • The GDPR compliance framework.
