About the Marsh & McLennan Companies logo
The Marsh & McLennan Companies (MMC) logo is part of the Tickericons pack — a hand-crafted set of logos for every company in the S&P 500. Each logo is manually redrawn to a consistent grid, weight, and corner radius so MMC sits cleanly next to other tickers in cap tables, dashboards, equity research, and fintech UI.
You get two styles: the trademark (just the symbol, ideal for grids and tight UI) and the full logo (mark plus wordmark, ideal when there's room to breathe). Both ship as scalable SVG, high-resolution PNG, and reusable Figma components.
Marsh & McLennan Companies was added to the S&P 500 on Aug 31, 1987 and is currently classified under the Financials sector.
