Oriol Saludes, COO and Co-Founder Kemiex

“I've been working with Altenburger since 2016. They have supported me both personally and professionally and always went the extra mile. Thierry Thormann's corporate/M&A team and Luzi Cavelti's tax team are very professional, pragmatic, business-minded and experienced. I would highly recommend Altenburger to anyone looking for a law firm in Switzerland.” (April 2021)

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.”

Eric Grob, CFO and Co-Founder Greenreb

“We were very pleased with the fast and pragmatic definition and implementation of our legal setup including our stock option plan. Thierry Thormann, Luzi Cavelti and their teams were very responsive, client-oriented and results-driven, which distinguished them from other legal partners we worked with.”
