Hugh Carlson
CEO, Three Crowns LLP
Hugh Carlson is the CEO and General Counsel of Three Crowns LLP. Since joining at the firm’s launch in 2014, he has helped build Three Crowns from a start-up boutique into one of the world’s premier dispute resolution practices.
A software engineer before he was a lawyer, Hugh has made technology a defining feature of the firm. Microsoft has called Three Crowns an “AI-powered company … bending the curve on innovation.” The Financial Times has recognized the firm’s AI work in successive years, including its use of Claude Code and OpenAI Codex to build enterprise-grade software tailored to practice. With Stanford’s Legal Innovation through Frontier Technology Lab (liftlab), Hugh co-led the development of an AI-powered cross-examination platform that won the FT’s Innovative Lawyers award for best training innovation.
Hugh has represented large multinationals and sovereigns in their most complex, high-stakes disputes. Clients and peers in Lexology Index describe him as “absolutely phenomenal,” “a great strategist,” and “integral to the success of Three Crowns,” and he has repeatedly been named a leading litigator in Lawdragon’s 500 Leading Global Litigators. He also counsels clients on the deployment, governance, and regulatory compliance of AI systems, drawing on his combination of legal and engineering expertise.
Hugh has lectured at Harvard Law School since 2019. He is admitted to practice in New York and the District of Columbia. He is a Certified Information Systems Security Professional (CISSP).
