Medium-sized agencies offer the perfect balance of speed, expertise, and hands-on partnership—making them ideal for modern CMOs seeking agility and results without the red tape of large networks.

Today’s marketing leaders face a growing paradox: the need for agility at scale. As CMOs and marketing executives seek new agency partners, many instinctively gravitate toward large holding company networks—assuming bigger automatically means better. Yet, time and again, the most impactful and transformative partnerships come from medium-sized agencies—the sweet spot between enterprise-level execution and boutique creativity.

Why Size Matters (But Not How You Think)

Medium-sized agencies combine the best of both worlds: the strategic sophistication and cross-channel expertise of large networks, coupled with the speed, flexibility, and accountability of smaller shops. Thanks to their size, they can move faster, stay closer to the business, and behave like an extension of your in-house team.

According to the Association of National Advertisers (ANA), the average agency relationship has increased from 3.2 years in 2016 to 7 years in 2025—a 118% increase. This reinforces that successful relationships are built over time, not overnight.

In today’s volatile marketing climate—marked by shrinking budgets and increased pressure for ROI—agency agility isn’t just an advantage; it’s a necessity. Gartner’s 2024 CMO Spend Survey found that marketing budgets have dropped to 7.7% of company revenue, the lowest in a decade. This underscores the need for lean, performance-driven partnerships that deliver measurable business outcomes—and that’s where Overdrive shines.

Maximize Agility

Medium-sized agencies thrive on agility. They’re not bogged down by layers of corporate structure or red tape, which results in faster decision-making, expedited testing cycles, and real-time innovation through active collaboration.

In our experience, this responsiveness directly impacts performance. When a campaign opportunity arises—whether a cultural moment, market shift, or competitive change—medium-sized agencies can (and should) pivot in real time. Now more than ever, CMOs are seeking partners who can adapt strategy and execution within days, not weeks.

Senior Talent, All-In on Your Business

At many global networks, senior leadership often disappears after the pitch. At Overdrive, we embrace a hands-on culture where senior leaders—both strategists and executives—stay actively involved in client work. This ensures proper oversight, clear direction, and a partnership rooted in accountability, innovation, insight, and measurable results.

CMOs gain direct access to agency leadership who understand and care about their unique challenges and KPIs—not just account managers relaying notes from internal meetings.

Integration Across the Digital Ecosystem

Medium-sized agencies offer the integration today’s marketing complexity demands—without the siloed chaos that often plagues larger organizations. From paid search and SEO to creative, social, and analytics, integrated teams operate as a cohesive unit, aligned around unified goals and KPIs.

Built for Partnership, Not Politics

Perhaps most importantly, medium-sized agencies are built on relationships—not revenue structures. They prioritize partnership over volume, and they invest in relationships designed to last years, not months. This alignment fosters trust, transparency, and shared accountability—the same principles Overdrive brings to every engagement.

At Overdrive, our teams integrate with yours, sharing goals, ownership, and outcomes. We’re not your vendor; we’re part of your team—an embedded growth partner that scales with your business. Because when you win, we win.

The Takeaway

The modern marketing landscape demands more than capability—it demands chemistry. The right partner should be big enough to deliver, small enough to care, and bold enough to innovate.

For CMOs navigating the agency selection process, medium-sized digital marketing agencies like Overdrive represent the optimal balance of knowledge, experience, discipline, and energy—a winning combination purpose-built for today’s fast, data-driven, customer-first world.
