2025 CMO Survey: Why Increased Pressure and Lean Budgets Demand a Nimble Agency Partner

The 2025 Deloitte CMO Survey reveals a marketing landscape defined by high expectations, intense scrutiny, and the ever-present need to prove value. For marketing leaders facing these conditions, the decision to hire a traditional, high-overhead advertising agency versus building the capabilities in-house is being reshaped.

The data points to an urgent need for efficiency, senior expertise, and measurable outcomes—all of which favor a strategic, nimble agency model over the internal complexity or bloated costs of the past.

#1 Challenge: Proving Marketing’s Financial Impact

The single most pressing issue for marketing leaders is still “Demonstrating the impact of marketing actions on financial outcomes” (64.0% of marketers report this as a challenge). This difficulty is compounded by dramatically increasing pressure from the C-suite:

• CFO Pressure: Increased to 63% (up 52% since Fall 2023).
• CEO Pressure: Now at 61%.
• Board Pressure: Stands at 50%.

In an environment where every dollar must be justified, CMOs can no longer afford agency partners who hide behind jargon or vanity metrics. They require a partner whose focus is rooted in Strategy, Measurement, and Analysis.

#2 Challenge: The Great Talent Squeeze

Internal talent struggles are worsening, creating a perfect case for outsourced expertise. “Hiring top talent” is the biggest people challenge for marketing organizations (41.2%). Why is hiring so difficult?

• Scarcity of talent: 16.7%.
• Difficulty finding expertise: 16.7%.

Critically, companies are already responding by changing their hiring mix. The percentage of full-time employee hires is decreasing (from 82.5% in 2019 to 77.9% in 2025), while planned hires for full-time independent contractors and part-time contractors are growing.

This trend validates the model of leveraging a select team of agency and marketing vets externally. Instead of engaging in a difficult, expensive competition for specialized full-time talent, an agency built on senior, flexible expertise instantly plugs the company’s capability gap, bypassing the internal hiring struggles.

#3 Challenge: Prioritizing Efficiency in a Tightening Budget Landscape

While overall marketing budgets are showing signs of recovery (overall spending increased 3.3% in the prior year), the growth rate is significantly slower than the 5.8% reported in Fall 2024. Simultaneously, traditional advertising spending is in a predicted negative growth territory (-0.3%) for the next 12 months.

This cautious environment underscores the need for a more efficient approach:

• Maximize Digital Spend: Digital marketing spending, while also slowing, still saw a 7.3% growth rate. This growing budget must be protected and maximized.
• Embrace AI for Cost Reduction: The use of AI in marketing is delivering tangible financial benefits, including a 10.8% reduction in marketing overhead costs.

An agency that operates a leaner, more efficient model is perfectly positioned to serve the modern CMO. They are not burdened by the high overhead of a traditional firm and can readily integrate the new efficiencies of AI, ensuring that a greater percentage of the client’s budget goes directly toward strategic execution and campaign performance.

In 2025, the market isn’t rewarding size; it’s rewarding precision. Marketing leaders need a partner who can match the agility and senior focus required to succeed in this complex, high-pressure environment.
