Stagwell Launches Agent Cloud Toolkit for SMBs
Stagwell’s software arm, The Marketing Cloud, expanded its Agent Cloud platform with a 10-agent AI-powered marketing toolkit aimed at small and medium-sized businesses and in-house agencies. The subscription product is positioned to help lean marketing teams execute campaigns without hiring additional staff and to drive recurring SaaS revenue for the holding company. The article notes The Marketing Cloud surpassed $105 million in revenue in Q4 2025 and grew 41%, and Stagwell CEO Mark Penn identified the unit as one of the company’s fastest-growing segments in recent earnings commentary. The announcement underscores Stagwell’s strategy of monetizing AI-driven software alongside its traditional agency services.
Stagwell Media Launches as Global Media Agency
Stagwell, the challenger agency network, has launched a new global media agency, Stagwell Media, which will be built on the foundation of its existing performance marketing agency Assembly. The new agency will be led by Liz Rutgersson, who recently joined as Assembly's CEO. Rutgersson emphasized that Stagwell Media is not an umbrella brand and that other Stagwell agencies like Crispin and Gale will continue to operate independently. The launch comes as competitors like WPP have consolidated their media offerings into umbrella brands. Rutgersson stated the new agency aims to fill a gap between traditional, complex agency models and fragmented specialist providers, with a strong focus on agentic AI and speaking to machines, not just human audiences. The announcement was made during Advertising Week New York.
Stagwell Unveils AI Search Tool for Enhanced Brand Visibility
Stagwell launched Stagwell Search+, an agent-based platform built with startup Emberos and developed by Assembly, Stagwell’s global omnichannel media agency. The platform is designed to improve brand discoverability and business outcomes within AI-driven search and LLM-generated answers by monitoring brand representation, predicting outcomes, coordinating cross-team workflows, and enforcing governance. Search+ was piloted over the past year and is being scaled across Stagwell’s agency network; Assembly reported one early software-client saw a 57% increase in visibility in AI Overviews. The platform uses fixed workflows (“fixed packs”) across paid, owned and earned channels and surfaces predicted and actual lift tied to business outcomes. Named AI agents include Sonar, Pilot, Flow, Merchant and Echo.
