Alliott Global Alliance

What Alliott Global Alliance does

Alliott Global Alliance is a London-headquartered international alliance founded in 1979 that brings together 236 independent accounting and law firms across 105 countries, 259 cities, and six continents, employing a combined 8,181 professionals. The alliance operates a membership model in which each member firm retains its independence while gaining access to a coordinated cross-border referral network, the AGA brand, shared marketing assets, and a centralized digital collaboration platform (AGA One / Members Portal). Member firms deliver services directly to clients, with the alliance facilitating introductions, multi-jurisdictional project coordination, and standards consistency rather than selling professional services itself.

Service delivery is organized into Core Global Solutions (Tax, Accounting & Audit; Business Legal; Payroll & HR; Company Secretarial) and Specialist Global Solutions (Cross Border M&A, Fraud & Asset Recovery, Franchising, Private Wealth, Global Mobility, Transfer Pricing, Tech & Investors, Aviation and Support Services). The alliance's proprietary technology surface comprises the AGA Members Portal and the ReloTalent global mobility assignment-management platform, integrated with preferred technology partners including CaseWare, Engineered Tax Services, and Xe. Approximately 10,000 audits are reportedly conducted annually by member firms, and in 2022 the alliance generated US$11,373,500 in referral income across member firms (76% response rate), with members reportedly earning 3.5-4x their membership fees in annual ROI.

The alliance monetizes through recurring membership fees paid by member firms, supplemented by event, training, and partnership-related revenue at the central Executive Office level. Its primary customer segments are mid-sized international businesses and SMEs with cross-border operations, plus organizations with globally mobile workforces. The alliance is privately held with no parent company, no external funding, and no subsidiaries; it is governed by an Executive Office led by CEO Giles Brake and adds new member firms through a vetting process — recent additions include Palomo Abogados in Guatemala (2025-11), Albagli Zaliasnik in Chile (2026-02), and Phillips Nizer LLP in New York. Consecutive Chambers and Legal 500 rankings in 2026 underscore its standing as a credible alternative to Big Four international networks for growing international businesses.
