Woss & Partners

What Woss & Partners does

Wöss & Partners is a Mexico-headquartered international arbitration and trade law firm founded in 1994 by Dr. Herfried Wöss and Adriana San Román, operating through two primary legal entities — Wöss & Partners, S.C. in Mexico City and Woess & Partners LLC in Washington DC — with additional offices in Vienna (representative), Lima (in alliance with CEO Abogados), São Paulo, and Curitiba. The firm is organized around six practice areas: Arbitration, Damages, Infrastructure, Energy, Trade, and Corporate, with a core specialization in complex damages quantification for income-generating contracts and investments. Its competitive foundation rests on the founding partners' authorship of the Oxford University Press monograph 'Damages in International Arbitration under Complex Long-term Contracts,' the Advanced Seminar on Damages in International Arbitration© training program delivered with ICC Austria and other partners, and individual credentials including Legal 500 Hall of Fame, Legal 500 Powerlist Latin America, International Who's Who of Commercial Arbitration, and 2022 European Commission arbitrator list inclusion.

The firm's service offering is project-based legal counsel rather than a technology product; its 'core technology' is doctrinal — proprietary damages methodology, multilingual capability across 6+ languages, and individual partner reputations in international arbitration forums (ICC, LCIA, ICSID). Revenue is generated through professional services billing on bespoke matters — representing clients as counsel, serving as arbitrators, and providing expert opinions on damages — with no publicly disclosed pricing model and no subscription or technology-licensing revenue. Customer logos include a large French energy corporation, Bimbo, Stöcklin Logistik, Techint, ThyssenKrupp, and a European third-party funder, across matter sizes ranging from US$100 million to US$280 million. Go-to-market is sales-led and reputation-led, relying on partner recognition in legal directories, scholarly publication, conference participation (Legal 500 GC Summit Mexico), webinars, and the Kluwer Arbitration Blog rather than performance marketing or channel partnerships.

Commercially, the firm operates as an independent professional services partnership with no disclosed institutional investors, parent company, or subsidiaries, and no public funding rounds. The operating footprint spans Latin America, North America, and Europe, with geographic emphasis on Latin American infrastructure and energy disputes. Distribution is direct, via the multi-jurisdictional office network and the Lima alliance with CEO Abogados.
