No. The nationality of the company founders is irrelevant. Only when the corporate bodies are filled do regulations apply:
If your employment contract mentions an obligation to notify in the event of a sideline, the employer's consent must be obtained. This is normally granted, provided that the employer does not compete with the sideline and does not affect his own performance.
- PLC: At least one member of the board of directors or one director with individual signing rights must be permanently resident in Switzerland (nationality no longer plays a role).
- LLC: At least one managing director with individual signing rights must be resident in Switzerland.
