The MX Group

The MX Group (often branded simply as MX) is one of the largest independent B2B marketing agencies in the United States, headquartered in Burr Ridge, Illinois, just outside Chicago. Founded in 1989, the agency’s mission is to “impact the marketplace for companies that impact the world,” with an exclusive focus on business-to-business brands. Over more than three decades, MX has built a reputation for creating meaningful end‑to‑end buying experiences that help clients navigate long, complex, multi‑stakeholder sales cycles.

MX positions itself as a B2B Growth Partner rather than a traditional agency, combining strategy, creative, demand generation, content marketing, digital experience, data & technology, and media under one roof. Its “Market Experience” and “Power of X” frameworks emphasize connecting every touchpoint in the buyer journey — from brand awareness and thought leadership to lead generation, ABM and sales enablement — so marketing activity translates into pipeline and revenue impact.

The agency has been consistently recognized in B2B Marketing’s US and Global Agencies Benchmarking Reports, including rankings as the #2 largest independent B2B agency in the U.S., a top B2B demand generation agency, and a top B2B brand agency. It was named B2B Marketing’s Agency of the Year in 2022 and has repeatedly been honored as one of the Best and Brightest Companies to Work For in Chicago and in the U.S. MX has also grown through strategic moves such as welcoming content marketing specialist Imagination into the agency, expanding its U.S. footprint and deepening its content and thought leadership capabilities.

MX serves a broad cross‑section of B2B industries, including manufacturing and industrial, energy and utilities, automotive, financial services, healthcare, legal services, packaging, trade associations, technology and SaaS. Through its partnership with U.K.-based agency Bray Leino and other collaborators, the firm supports global go‑to‑market initiatives while maintaining a strong Midwest U.S. base. With a team of more than 160 employees and a roster of several dozen active clients, The MX Group occupies a strong position in the B2B demand generation and brand strategy agency landscape.
