Calvin Koo counsels financial technology and Web3 clients in high-stakes international litigation and investigations. This includes leading global dispute resolution campaigns that require highly coordinated multi-jurisdictional activity. For claim monetization cases, his strategies synthesize tracing digital assets on blockchains and advocating in courtrooms around the world to maximize recovery value. He also applies similar techniques on behalf of victims of fraud to recover cryptocurrency or traditional assets, as well as secure significant damages.

Mr. Koo additionally represents clients, including ultra-high-net-worth individuals, pursuing offensive and defensive strategies related to cross-border government enforcement matters and regulatory enforcement actions. He advises clients throughout Asia in sensitive international investigations by government and regulatory agencies, including the U.S. Securities and Exchange Commission; the U.S. Department of Justice; the Hong Kong Independent Commission Against Corruption; and the Hong Kong Securities and Futures Commission.

Before joining Kobre & Kim, Mr. Koo practiced at Winston & Strawn LLP, where he represented corporations and their executives in white-collar investigations, class-action securities disputes, bankruptcy, and other related litigation.
