Both are fully recognised Swiss legal entities with limited liability, but they differ in four practical ways that matter for fintech operators. Capital: a GmbH requires CHF 20,000 fully paid in; an AG requires CHF 100,000, of which at least CHF 50,000 must be paid in at formation. Privacy: AG shareholders are not publicly disclosed in the commercial register; GmbH associates are named publicly, which matters for beneficial owners who prefer confidentiality. Share transfer: AG shares are transferred by a simple share deal with no commercial register update required, making future ownership changes straightforward; GmbH share changes require general assembly approval and commercial register registration. External investment and tokenization: AG shares can be tokenized and are suited to external investor rounds; GmbH shares are not tokenizable and are generally not suitable for third-party investment. Most international fintech operators choose the GmbH for its lower capital requirement and simpler setup. The AG is recommended for larger operations, clients seeking external funding, or those planning to tokenize equity. Contact us to discuss which structure fits your business.
