Trusted by founders at every stage
Through the recommendation of another startup founder, we came across LEXR. Michele and the corporate team guided us through the entire process of the financing round. When we write an email, we receive a reply in no time, and time is taken to explain legally complex issues in a simple and understandable way.
The cooperation was very good and I can already predict that we will approach LEXR again. We had a good feeling right from the start. This was then confirmed throughout the entire process. We had the feeling that LEXR was part of the deskbird team.
LEXR’s expertise in legal matters was invaluable and ensured a smooth handling of all legal matters in the seed round. This helped us to focus on growth. Working with LEXR felt more like they were part of RIBE. Extremely professional, reliable, very uncomplicated and always available for questions. This is not only our opinion, we have also received very positive feedback from the investors involved.
How we solve your challenges
From kick-off session to notarised closing — the full conversion, in one team.
Our legal experts explain the conversion process and discuss all key parameters with you — your current setup, desired target structure, and the implications of your balance-sheet analysis. You leave the first session with a clear picture of what's ahead.
The AG requires a minimum share capital of CHF 100'000. Where the existing GmbH share capital falls short, we prepare all documentation for the necessary capital increase as the first step of the conversion — clean, notary-ready and explained line by line.
We prepare every document the conversion requires: new articles of association, board-of-directors appointment documents, shareholder resolutions and all corporate-action paperwork — tailored to your company, not copy-pasted from outdated templates.
LEXR coordinates the entire process with all involved parties — the auditor, the accountant and the notary — so you only need to sign the documents. No chasing multiple advisors or managing conflicting timelines.
The conversion of your GmbH into an AG is formally closed in front of our notary public. From this moment your company operates as an AG — investor-ready and built for growth.

GmbH to AG conversion FAQ
The questions founders ask us most before starting their conversion.
The AG (Aktiengesellschaft) is the preferred structure for growth-oriented companies: it is better suited for external investors, allows for easier share transfers, and is the standard form for VC-backed startups and companies planning to raise capital. A GmbH can be perfectly adequate early on, but many founders choose to convert once they start engaging investors or employees with equity.
An AG requires a minimum share capital of CHF 100'000, of which at least CHF 50'000 must be paid in. If your GmbH's current share capital is below this threshold, a capital increase is required as the first step of the conversion.
The flat fee covers the full legal work: the kick-off session, legal advice, drafting of all conversion documents (new articles of association, board appointment, shareholder resolutions, capital-increase documentation), and coordination with the auditor, accountant and notary. Notary fees and any official registry fees are invoiced separately at cost.
The timeline depends mainly on the auditor's availability and the commercial register's processing time. Once all documents are signed, registration typically takes a few weeks. Our team coordinates proactively to avoid unnecessary delays.
Yes. Swiss law requires an auditor to evaluate the financial situation of the company as part of the conversion process. We coordinate with your existing auditor — or help you find one if needed.
Yes. LEXR has its own notary practice. The closing of your conversion takes place in front of our notary public, so you have one team managing the entire process end to end.
