Avenue Z, one of marketing’s fastest-scaling agencies, has planted a bigger flag in New York. The firm has opened a new office at 156 Fifth Avenue in the Flatiron District—nearly doubling its footprint in the city and signaling its ambitions to become a national powerhouse in marketing and communications.

The new office isn’t just real estate bragging rights. It’s designed as a central hub for Avenue Z’s integrated campaigns, blending earned, owned, and paid media. The move also marks a decisive expansion of its public relations division, giving the firm a strategic edge as brands look for communications partners that can seamlessly combine traditional PR with digital and AI-driven strategies.

Why This Matters

PR has become increasingly intertwined with performance marketing, as companies seek visibility across both human and machine audiences. Avenue Z is leaning into that convergence, making PR part of its broader “AI Optimization” model—aimed at helping brands recover traffic and visibility in a search landscape reshaped by generative AI. It’s a timely bet, as competitors scramble to update their offerings for the AI era.

The People and Clients Behind the Push

Founder and CEO Jeffrey Herzog called the Flatiron office “a reflection of the momentum we’re building,” pointing to recent client wins including Republic Technologies, Prospero, Ualett, and Core VC. The agency continues to service long-term partners such as Sagard, Torch Capital, Athena Capital, and Tassat.

Leadership has also been beefed up, with new hires across media, strategy, and content, alongside internal promotions. VP and Managing Director Libbie Wilcox will anchor the Flatiron team, bringing deep expertise in strategic communications for tech, finance, venture capital, and private equity.

“We’ve built the PR team from the ground up, mixing outside hires with homegrown talent,” Wilcox said. “This office gives us a space to move fast, think big, and deliver meaningful outcomes for clients who are reshaping finance and technology.”

The Bigger Picture

The expansion places Avenue Z squarely in the middle of Manhattan’s competitive agency landscape, where rivals like Edelman, Finn Partners, and Highwire are also fighting for dominance. But with its integrated model—PR fused with performance media, digital marketing, and content strategy—the agency is betting that convergence, not specialization, will define the next chapter of communications.
