Independent Firms.
One Alliance.

GAA selects its members based on their expertise, geographic focus, and proven track record in their market, ensuring each boutique advisory firm brings a level of local depth that generalist firms cannot replicate, while providing the global connectivity and reach that independent firms cannot build on their own.

GAA members serve institutional investors, family offices, and companies across Europe, Asia-Pacific, the Americas, Africa, and the Middle East.

On track to 50 founding members.
