Stephan is as much an engineer as he is a lawyer. He works with world-leading web 3.0 founders on a broad spectrum of corporate and regulatory matters, including early- and growth-focused financings, securities law, OFAC/FinCEN, corporate structure and formation strategies, international and cross-border transactions and structures, and other issues. His clients are high-profile market leaders in the blockchain and cryptocurrency space and include layer one and two protocols, cryptocurrency bridges and exchanges, NFT marketplaces and projects, DeFi platforms and protocols, web 3.0 game developers, decentralized autonomous organizations (DAOs), and machine learning and AI companies.

Before joining Fenwick, Stephan was a technology litigation attorney at a global law firm where he handled sensitive regulatory investigations of large web 2.0 technology companies. He also co-founded an AI company and served as a pro bono law clerk to the Hon. Esther Salas, in the District of New Jersey, and as a law clerk to Justice Walter Timpone, on the Supreme Court of New Jersey. He worked for the White House Senior Advisor on Privacy during the Obama Administration and co-taught a Python-based course called Computer Programming for Lawyers while in law school.
