What Marsh does
Marsh is a global insurance broker and risk advisory firm operating in 130 countries with 95,000+ employees and approximately $27 billion in annual revenue (FY2025). Headquartered in New York and publicly listed on the NYSE under ticker MMC, Marsh was rebranded from Marsh McLennan Companies in January 2026 and operates four businesses: Marsh (risk and insurance services), Guy Carpenter (reinsurance), Mercer (people and investments), and Oliver Wyman (management consulting). Marsh Risk, the core operating unit, serves large multinational corporations across 30+ industry verticals including Manufacturing, Real Estate, Private Equity and M&A, Higher Education, Government, and Multinational Employers.
Marsh's technology platform centers on the Risk Companion suite launched April 2026, an AI-powered analytics system connecting Marsh's proprietary global risk dataset to actuarial models through two initial modules: Renewal Companion (real-time modeling of retentions, limits, deductibles, and coverage for casualty and property lines) and Captive Companion (automated captive financial reporting). Supporting platforms include Project Leapfrog (LLM-based risk strategy tool in testing), Sentrisk (AI-powered supply chain risk analytics), Cyber Self-Assessment (industry-standard cyber risk evaluation), Coverholder360 (MGA data management compatible with London Market DA SATS standards), and the Cyber Risk Intelligence Center (dark-web monitoring plus claims analytics). The Cyber ECHO facility provides $200 million of coverage capacity — the largest cyber facility of its kind — covering 1,500+ clients with $55 billion in cumulative cover since 2016.
Marsh generates revenue primarily through commissions on insurance placements and fees for risk advisory services, with additional revenue from reinsurance brokerage (Guy Carpenter), warranty and indemnity insurance for M&A transactions ($91.6 billion in limits placed globally in 2025, up 34% year-over-year), and captive insurance solutions. The go-to-market is enterprise field sales through direct offices in 130 countries, supplemented by the Lloyd & Partners MGA program and specialty wholesale channels. Pricing is highly customized based on risk profile, coverage scope, industry, and geography. Q1 2026 consolidated revenue was $7.6 billion, up 8% year-over-year.
