Stein IAS

What Stein IAS does

Stein (formerly Stein IAS) is a global B2B marketing agency that provides brand-to-demand services to large enterprise clients across multiple industries, including healthcare, financial services, technology, real estate, automotive, transportation, and pharmaceuticals. The company's core product is its proprietary Brand-to-Demand Experience (BDX) model, which integrates brand and demand marketing into a unified offering, supplemented by the BDX Playbook co-developed with WARC and LinkedIn, the annual Global Most Valuable B2B Brands Index produced with Brand Finance, and a proprietary AI platform launched in May 2025. Named enterprise clients include HSBC, Merck, GE Healthcare, Samsung, JLL (Global Creative Agency of Record), Wolters Kluwer, Juniper Networks, Celonis, and Bentley.

The agency operates under the MSQ Partners global agency group with regional hubs in New York, London, Manchester, Amsterdam, Singapore, and Shanghai, delivering strategy, creativity, content development, digital innovation, thought leadership, and full-funnel media capabilities. Stein generates revenue through professional services engagements, with quote-based pricing for customized enterprise mandates rather than standardized packages. New business is pursued through industry awards (Stein is described as one of the most highly awarded B2B agencies globally), industry events including the LIONS B2B Summit at Cannes Lions, thought leadership content, and direct enterprise field sales.

The company was formed through the 2015 merger of Stein and IAS B2B Marketing, operating as Stein IAS until May 14, 2025, when it rebranded to simply Stein. The legal entity is Stein IAS Holdings LTD, incorporated in the United Kingdom, and Stein operates as a wholly owned subsidiary of MSQ Partners. Leadership includes Kate MacNevin as Global CEO and Tom Stein as Founder, Chairman, and Chief Client Officer. Stein's strategic priorities in 2025 are anchored by the BDX framework, its AI platform, and a Brand-to-Demand Maturity Study conducted in partnership with the ANA.
