Assembly

Stagwell's flagship global media agency network, competing with GroupM, Dentsu, and IPG Mediabrands agencies as a technology-integrated media buying and planning operation

Assembly, now rebranded as Stagwell Media as of October 6, 2026, was the flagship global media agency operating under Stagwell Inc.'s Stagwell Media Network. The agency was formed through the merger of the original Assembly agency and ForwardPMX, combining media buying, planning, and performance marketing capabilities into a single integrated network spanning approximately 1,900 employees across 30+ offices in more than 20 countries. Assembly served as a full-service media agency offering data-driven media planning and buying, digital performance marketing, search, programmatic, social, and analytics services to a broad range of enterprise clients globally. During its operational life, Assembly distinguished itself through its integration of technology and data analytics into traditional media agency services, leveraging Stagwell's proprietary technology stack alongside third-party platforms. The agency competed directly with major media agency networks including Dentsu, GroupM agencies, and IPG Mediabrands, positioning itself as a more agile and technology-forward alternative to legacy holding company agencies. Its global footprint allowed it to serve multinational brands with consistent cross-market media strategy and execution. The Assembly brand was retired when Stagwell sunsetted it in favor of the Stagwell Media rebrand, consolidating the agency's identity more directly under the parent holding company's umbrella. The entity continues to operate as Stagwell Media, preserving its capabilities, talent, and client relationships under the new brand. Note that Assembly (assemblyglobal.com) is entirely distinct from Assembly Industries, the Advent International-backed e-commerce software platform that acquired Pacvue.
