What Wenger & Vieli does

Wenger Vieli AG is a privately held Swiss law and tax advisory firm headquartered in Zurich (Dufourstrasse 56) with a branch office in Zug (Metallstrasse 9), operating since 1971 under a partner-owned Aktiengesellschaft structure.

The firm serves three primary client segments: corporations and institutional investors (banks, PE firms, strategics) on M&A, financing and regulatory matters; high-net-worth individuals and families on estate, tax and wealth structuring; and startups/VC investors via a dedicated Start-up Desk handling 60-70 financing rounds annually plus formation, ESOP/PSOP and exit support. A niche Sports Desk serves athletes, clubs, associations and event organizers. Distribution is direct-engagement, augmented by Meritas and WTS Global network referrals for cross-border mandates.

The business model is professional-services fees (hourly and quoted mandates) supplemented by publicly disclosed fixed-fee Start-up Desk packages (company formation CHF 500-3,300, financing rounds CHF 6,500-18,000, ESOP/PSOP CHF 2,500, data protection CHF 2,500). The firm complements traditional advisory with the Digital Lawyer self-service platform providing standardized German/English contracts, checklists and automated commercial register document generation. The firm has no public listing, no subsidiaries, and no external funding rounds; ownership sits with the partner group.
