# High-Level Overview
Wenger Vieli is a Swiss law firm providing legal and tax consulting services to businesses and individuals across corporate law, private equity, dispute resolution, and specialized sectors including fintech and sustainability.[1][5] Based in Zurich and Zug, the firm operates as a full-service legal advisor with approximately 150 employees in Switzerland, serving both domestic and international clients.[4][6]
The firm's mission centers on delivering comprehensive legal and tax solutions with a focus on professional excellence and pragmatic problem-solving.[6] Rather than functioning as an investment firm, Wenger Vieli operates as a professional services firm advising investment companies, family offices, institutional investors, and founders on complex transactions.[2] The firm is particularly recognized for its expertise in private equity transactions, cryptocurrency and blockchain law, and environmental/sustainability-focused legal matters.[2][3][8]
# Origin Story
Wenger Vieli was established over forty years ago and was formerly known as Wenger Vieli & Belser.[1][7] The firm has evolved from a traditional Swiss law practice into a multi-service legal advisor with deep expertise across commercial, tax, and specialized practice areas. This longevity has enabled the firm to build substantial experience in advising on complex domestic and international transactions.[6]
# Core Differentiators
# Role in the Broader Tech Landscape
Wenger Vieli occupies an important position in Switzerland's legal infrastructure for emerging sectors. The firm has positioned itself at the intersection of fintech innovation and regulatory compliance—advising on ICOs, tokenization, blockchain platforms, and distributed ledger technology at a time when these areas require specialized legal guidance.[8] The firm's work with green tech companies and sustainable finance platforms (such as radicant, a digital bank focused on sustainable financial solutions) reflects its alignment with the broader ESG and climate tech trends reshaping global finance.[3]
By serving as legal counsel to investment companies and family offices in private equity transactions, Wenger Vieli facilitates capital deployment into growth-stage companies, thereby influencing deal flow and transaction structures within Switzerland's startup ecosystem.[2]
# Quick Take & Future Outlook
Wenger Vieli's future trajectory will likely be shaped by continued specialization in high-growth legal domains—particularly fintech regulation, sustainable finance, and cross-border private equity transactions. As regulatory frameworks around cryptocurrency, ESG, and digital finance continue to evolve globally, the firm's existing expertise positions it well to serve clients navigating these complex landscapes. The firm's international network and multilingual capabilities will remain valuable as Swiss-based companies increasingly pursue cross-border transactions and as global capital seeks exposure to Swiss innovation hubs.
