When we’re young, life is about exploration. We experiment, meet new people, and enjoy the thrill of variety—often spreading our energy across numerous friendships and fleeting relationships. Yet, as we mature, we realise that deeper, more meaningful relationships are what truly add value to our lives. This same lesson can be applied to how businesses approach their agency partnerships.

The Polygamous Approach: When Scale Demands Specialists

At scale, large organisations often adopt a polygamous mindset, engaging multiple agencies—each specialising in a specific area such as SEO, PR, creative, or media buying. For businesses operating at significant scale, this can make sense: their marketing needs are complex, and individual agencies bring highly specialised skills and resources to solve specific challenges.

However, this approach demands sophisticated management structures. Companies must coordinate multiple partners, ensure cohesion across channels, and maintain a single, clear vision. The risk, even for large businesses, lies in fragmentation:

  1. Mixed Messaging – Without a unifying strategy, different agencies may interpret objectives differently, leading to brand inconsistency.
  2. Duplication and Silos – Efforts often overlap, or opportunities for synergy are missed because no single agency has visibility of the whole picture.
  3. Coordination Overhead – Managing multiple agencies requires significant internal resource to steer, align, and measure performance across partners.

The reality is, while a polygamous model works for businesses with scale, smaller and growing organisations often find themselves stretched thin, with time and budget lost to inefficiencies.

The Monogamous Approach: A Single Agency Partner in the Early Years

For businesses in their formative years or stages of development, the need for cohesion and clarity is far greater. Early-stage businesses are building their identity, their voice, and their reputation in the market. At this point, a single, trusted agency partner often delivers the most value.

Here’s why:

  1. Holistic Understanding – A single agency takes the time to deeply understand your business—its goals, its challenges, and its ambitions—without the need for constant onboarding or repeated explanations.
  2. Unified Vision – A full-service agency ensures every element of your marketing strategy, from creative to digital to PR, is aligned under one consistent narrative. This cohesion is crucial when budgets are tight and every message must deliver impact.
  3. Efficiency and Simplicity – Managing multiple agencies demands significant resource, a luxury many growing businesses don’t have. A single agency partner removes the overhead of coordinating numerous specialists and becomes an extension of your team.
  4. Scalable Growth – As your business grows, a full-service partner evolves with you. They can bring in specialist skills when needed, seamlessly managing these elements within a broader strategy.

Recognising the Need for Specialists

It’s important to acknowledge that no single agency can do everything—nor should they. Specialist skills, such as niche technical expertise or highly complex campaigns, may occasionally require external support. However, a trusted full-service partner can act as the central hub, integrating specialists into the broader strategy while ensuring cohesion and alignment.

Rather than fragmenting your efforts too early, this model allows you to benefit from the depth of a singular relationship while still tapping into expertise where necessary.

Building a Deeper, More Meaningful Partnership

Choosing a full-service agency isn’t about limiting options—it’s about creating a strong foundation. Like any meaningful relationship, the best results come from trust, understanding, and shared ambition.

For businesses in their early stages, this partnership can be transformative:

  • Consistency in messaging, delivery, and strategy.
  • Simplicity in communication and coordination.
  • Scalability as your business grows and new opportunities arise.

When you reach the scale where multiple agencies are required, you’ll already have a strong foundation and clear identity—developed in partnership with a trusted agency that understands your business at its core.

Single Agency vs Multi Agency: What’s Best For Your Business?

In life, as in business, there’s a time for exploration and a time for commitment. For businesses early in their journey, the depth and cohesion offered by a single, full-service agency far outweigh the fragmented approach of multiple partners.

As you scale, the lessons learned from this deep relationship will serve you well—providing clarity, consistency, and a strategic partner who can help guide the integration of specialists when the time is right.

The question, then, is this: do you want to spread your energy thin across many partners, or invest deeply in the one that can help you grow?
