Walker Sands is sharpening its growth trajectory with a heavyweight addition to its board. The integrated B2B growth services agency has appointed George Gallate—one of the industry’s most seasoned marketing executives—to guide its next phase of expansion. The move follows Walker Sands’ recent partnership with Mountaingate Capital, signaling a clear push toward scaling capabilities, accelerating acquisitions, and expanding its influence across the enterprise technology market.

Gallate enters with a résumé that few in the sector can match. Over a 40-year career, he has built, led, and transformed global marketing organizations. His 27-year tenure at Havas included serving as Global CEO and Chairman of Havas Digital, where he helped scale the business into the world’s largest digital network during the 2000s. His track record extends to leading the Rimm Kaufman Group through its sale to Merkle in 2014, eventually becoming Merkle’s Global Chief Marketing Officer.

Today, Gallate is CEO of the consultancy MKTG2.U and serves as an independent board member and investor across several major marketing services companies, including Tinuiti, Real Chemistry, Bounteous, Anteriad, Bond Loyalty, and WebFX. His experience spans every corner of the ecosystem—from digital transformation to data-driven marketing to operational leadership. He has also held previous board roles at Mars United Commerce and co-founded NEAR, Networks for Emergencies and Relief.

His appointment marks a strategic moment for Walker Sands. As the agency doubles down on becoming the leading data-driven B2B growth partner, Gallate’s mix of operator insight, investor maturity, and advisory expertise is expected to play a central role. For the past eight years, he has helped shape and scale category leaders across the marketing services industry, making him a valuable guide as Walker Sands looks to strengthen its go-to-market model and broaden its services.

The timing is closely tied to Walker Sands’ acquisition by Mountaingate Capital. Backed by new investment, the agency plans to expand its capabilities across strategic communications, digital marketing, GTM strategy, marketing technology, revenue operations, and content and creative. The goal is clear: build a modern B2B growth services platform equipped to support enterprise clients through the full funnel, from brand strategy to pipeline acceleration.

Gallate said Walker Sands’ reputation as a trusted growth partner for major B2B brands made the opportunity compelling. He credited the agency’s Outcome-Based Marketing approach for driving measurable business results—a model he believes positions the company for global leadership in the B2B services category. His focus now will be helping the leadership team scale its capabilities and capture new market opportunities.

Walker Sands co-CEO Andrew Cross added that Gallate brings a rare combination of operational leadership and investor rigor—experience that aligns directly with the agency’s ambitions. With the marketing services landscape becoming more data-driven and acquisition-heavy, Gallate’s strategic guidance is expected to help Walker Sands accelerate growth without losing focus on client outcomes.

The broader takeaway: Walker Sands is signaling that it intends to compete at the top tier of B2B marketing services. Backed by capital, strengthened by leadership, and anchored by a performance-focused model, the agency is positioning itself to expand aggressively and deepen its role as a partner to enterprise technology brands navigating increasingly complex markets.
