G3

What G3 does

G3 is a global business intelligence and advisory firm headquartered in London, founded in 2004 as a spinoff from a larger intelligence firm. The firm operates three integrated service lines: Strategic Intelligence, which provides commercial, regulatory, and reputational intelligence to inform client decisions on transactions, partnerships, and market entry; Investigations and Disputes, which supports dispute resolution through asset tracing, internal investigations, fraud detection, and digital forensics; and Cyber Advisory, which delivers cyber maturity assessments, pre-deal due diligence, and penetration testing across offensive and defensive security domains. G3's core technology is a proprietary global network of human sources cultivated over 20+ years, operating in almost every country, supplemented by investigative tooling rather than a software product platform. The firm's competitive positioning rests on senior practitioners drawn from government intelligence services, investment banking, elite law firms, and law enforcement, collectively speaking 45+ languages.

G3 serves enterprise clients across three primary segments: private equity and investment funds (9 of the 10 largest global investment funds), major law firms (19 of the 20 largest global law firms by revenue), and global corporations including 7 of the 10 largest Western banks and Fortune 50 companies. The firm operates from six offices worldwide — London, New York, San Francisco, Singapore, Tokyo, and Abu Dhabi — and executes 1,000+ projects annually, with $40bn+ in award value provided through dispute-related investigations. Client engagements are project-based and retainer arrangements, with pricing bespoke and not publicly disclosed.

The firm's revenue model is professional services billing on a project and retainer basis. G3 sells through direct senior relationship management, engaging C-suite executives, deal teams, and legal counsel at top-tier clients. The firm is privately held, owned by management following a 2018 management buyout from a €15bn investment fund that had been the controlling shareholder since 2012. Since 2018, the firm has diversified its client base into private equity, sovereign wealth, and pension funds, deepened its regional offices, and relaunched a dedicated cyber advisory platform following the 2013 divestiture of its original cyber business. In 2024, the firm appointed Sir John Sawers (former Chief of MI6) as Chairman of the Advisory Board, and in April 2026 it opened a new London headquarters at 30 Portland Place.
