What Altenburger does

Altenburger is a Swiss law firm founded in 1984, providing integrated legal and tax advisory services across seven practice areas: Corporate/M&A, Tax, Real Estate, Dispute Resolution, Commercial & Contracts, Employment Law, and Banking/Finance/FinTech. The firm operates from three offices — Küsnacht (near Zurich, headquarters), Geneva, and Lugano — covering Switzerland's principal German-, French-, and Italian-speaking economic regions, and delivers services trilingually. Its visible headcount of approximately two dozen named professionals spans partner, counsel, senior associate, associate, and legal trainee tiers, and the firm serves a primarily corporate, high-net-worth, and cross-border-investor clientele with mandates connecting Switzerland to European and international counterparties.

The firm operates as a privately held partnership under the traditional Swiss professional services model, generating revenue through hourly and project-based professional fees across transactional advisory (M&A, corporate structuring, real estate) and ongoing counsel (tax, employment, compliance, dispute resolution). Its technology footprint is limited to standard marketing and communications tooling — Google Analytics, Google Tag Manager, Mailchimp, and Webflow — with no proprietary legal-technology platform, workflow automation, or AI-enabled product indicated in publicly observable material. The firm does not disclose revenue, headcount totals, or financial performance, consistent with a closely held partnership structure.

Marketing and pipeline development are executed through multilingual thought-leadership publications, ranked-directory visibility (consecutive Legal500 listings in 2025 and 2026 for Commercial, Corporate and M&A), and individual practitioner recognitions (Lexology Index Q&A Arbitration Thought Leaders 2026). Recent content output includes Swiss Investment Screening Law, cross-border M&A, and banking/financial services topics, signaling positioning in inbound-investment compliance and FinTech advisory. The firm has no visible M&A history, no funding events (private partnership), and no IPO or capital-markets activity.
