Brand manager vs agency: which does a growing brand need?

If your brand direction is clear and you simply need more output, an agency. If the direction is scattered, everyone describes the brand differently and no one is holding the decisions, a brand manager first. Most growing brands use both: the brand manager holds the direction, the agency produces the work.
When a brand starts to grow, the same question comes up: should we hand the work to an agency, or find someone to manage the brand? The two are often confused, because both "take care of the brand". But they solve different problems. Picking the wrong one usually costs more time than money.
What does a brand manager do?
A brand manager owns the direction of the brand. They decide who the brand speaks to, what it says, how it sounds and how it looks, and make sure those decisions hold everywhere. Most of the job is choosing and protecting, more than producing.
- Positioning and message: being able to say in one sentence why the brand is different.
- Consistency: making the website, deck, social media and ads look like they come from the same brand.
- Briefs and priorities: telling the agency or designer clearly what is needed, and deciding what comes first.
- Measurement: looking at what works and planning the next step around it.
What does an agency do?
An agency is production power. Design, content, shoots, campaigns, websites and ad management, delivered against a brief, by a specialist team, often at a speed one person cannot match. A good agency does the work well. Holding the long term direction of your brand is usually not its job, because an agency works with many clients and looks at each project through that project's brief.
Side by side
| Brand manager | Agency | |
|---|---|---|
| Core job | Direction, consistency, decisions | Production and execution |
| Time horizon | Months and years | Project or campaign |
| Point of contact | One person | Account manager and team |
| Cost structure | Salary or monthly fee | Project fee or monthly retainer |
| Best moment | When the brand is scattered or growing | When direction is set and output is high |
| What is missing | Large production capacity | Long term ownership of the brand |
When to choose which
A brand manager first, if...
- Founders, the sales team and the website describe the brand differently.
- You work with an agency and each piece is good, but together they do not look like one brand.
- You are preparing for a launch or a funding round and want solid ground.
Straight to an agency, if...
- Your brand book, positioning and voice are ready and someone on the team owns them.
- You need a specific project: a campaign, a shoot, a new website.
A third option: the fractional brand manager
For many growing brands, a full time senior brand manager is too early, and working with an agency alone leads to a scattered result. There is a middle path: an experienced person who runs the brand for a set scope and period without joining full time. This is called a fractional brand manager. I explain how it works in detail in what is a fractional brand manager.
In this model, the person holding the direction and the team doing the production can sit under one roof. That is how I work: I am your point of contact, and the design, development, content and advertising team of Rebel Co. Group, which I co-founded, steps in when needed. You do not have to find a separate agency or explain the brief from scratch every time.
An agency gives you a team. A brand manager gives you direct attention. What a growing brand usually lacks is not a team, but the one person who owns the brand every day.
Common questions
What is the difference between a brand manager and an agency?
A brand manager owns the direction and consistency of the brand and decides what gets done and why. An agency produces the work in that direction: design, content, campaigns, ads. One is direction, the other is production power.
Does a small brand need both a brand manager and an agency?
Not always. Early on, most brands need a clear direction first. Once the direction is set, an agency or freelancers are added as production needs grow. A fractional brand manager can bring both needs together under one point of contact.
What is a fractional brand manager?
An experienced brand manager who runs your brand for a set scope and period without joining full time. It gives you a senior view without the cost of a full time hire.
Why does a brand drift when working with an agency?
Usually because no one is holding the direction. An agency works to the brief. When each brief is written by a different person with a different view, the pieces can be good on their own and still not look like one brand together.
