Altenburger – Swiss Business Law Firm since 1978

Meet the Altenburger Professionals

Since 1978, we have continuously built our authority and reputation as an international business law practice. Growing from a small tax law boutique to a full service commercial law firm has been quite an adventure. We look forward to the years to come!

Client Endorsements and Industry Recognition

Maintaining our clients' continued trust by delivering measurable results is what is most important to us.

Yet, we are of course also pleased when the quality of our service is recognized publicly. Here is some of the recognition we have gratefully received from clients and peers in recent years.

Kaspar Adank, Founder and CEO of Soobr

"Thierry Thormann and Ralph Imoberdorf have the economic understanding and entrepreneurial mindset to ensure a sound legal structuring of a start-up within the framework of an optimal benefit-cost ratio. With their support, we have been able to close two rounds of financing cost-effectively and on advantageous terms."

Roger Meister, CEO / Partner, 2XIdeas

“We relied on Altenburger's services to structure our shareholders’ agreement, to define our employee participation program from a legal and tax perspective, and also to structure our international expansion in a tax-efficient manner. Not only was the legal and tax input from Thierry Thormann and Luzi Cavelti highly valuable, but we also appreciated the fact that we received substantial best-practices feedback from a busines perspective from them.”
