Adrian Courtenay is Founder of the GA-Courtenay Special Situations Fund and Managing Director and Head of Special Situations Strategy at GreenAsh Partners. The fund is a concentrated, event-driven UCITS built around a single recognition: that the identification of enduring winners can be engineered, not merely intuited. The fund pairs exposure to dominant, future-facing businesses — through modest gearing — with an always-on, positive-carry hedge. The result is amplified participation in the upside, paired with cost-efficient defence against market dislocation.

Adrian read biosciences at Oriel College, Oxford, taking a first as a Scholar, and brings a scientist’s instinct to investing: that frameworks, not flashes of talent, are what compound. Across close to fifteen years as a deep-dive analyst — at Tisbury Capital, a Citadel spin-off, and then in the Special Situations Group at D.E. Shaw & Co — he built the disciplines the fund now runs on. He launched it in October 2019, transferring it to GreenAsh Partners in 2023; in 2025 The Hedge Fund Journal named it Best Performing Event-Driven UCITS Fund over five years.

His investment approach targets a recurring archetype: the monopolistic superorganisation without which a high-growth industry cannot scale, owned through periods when the market has neither fully understood its position, nor that of the industry it leads. The approach is formalised in two proprietary frameworks, Superorganisation and Industrial Psychohistory, and in Adrian’s 2025 book The Super Organisation Secret. Adrian speaks at the Sohn investment conferences, and writes on the intersection of investing, artificial intelligence and human judgement.
