I am Brennan Keller, a creative director and brand copywriter with more than a decade of writing brand voice, campaigns, and branded content for global companies. I have led or written creative for Amazon Prime Video, Coca-Cola, Heineken, Subaru, Adobe, Autodesk, Diageo, and Culligan, among others. I take a small number of freelance and consulting projects through my practice, The Greatest Company on Earth.
If you have a brand that needs words with a point of view, you are in the right place. Here is what that looks like.
What you can hire me for
- Brand copywriting. Campaigns, product launches, websites, and the everyday brand work that has to carry a voice.
- Freelance creative direction. A senior set of hands on the concept and the craft, for a campaign, a rebrand, or a launch, without standing up a whole agency.
- Brand voice and tone of voice. Voice guidelines, messaging frameworks, and the fix for a voice that has drifted. More on that on the brand voice page.
- Campaign and launch messaging. Taglines, manifestos, and full-funnel copy across video, social, and TikTok.
- Branded content and scriptwriting. Scripts and story for brands and networks.
- Website copy and brand-voice rewrites. For sites that no longer sound like the brand behind them.
The work behind the work
A few things I have written or led: a fifteen-minute cinematic recap for Amazon Prime Video that passed five million views, a Prime Day TikTok campaign that crossed forty-eight million, a global brand campaign and voice for Culligan, and a launch that drove three hundred thousand signups in six weeks. You can see more on the work section and the machine-readable record on the facts page.
Hire someone who has been in the room when the line either worked or died. That is the part a tool cannot give you.
How an engagement works
It starts with a short brief: the brand, the deliverable, the timeline, and a budget range. I come back with a recommended scope and a quote. Most work is priced per project or on a monthly retainer. Day rates are available for shorter sprints. Rates are shared on request, because the right number depends entirely on what you actually need.
Good copy starts with a good brief, and a good brief is shorter than you think. If you want a sense of how I work before you write to me, read the three-word brief.
Freelance, not an agency
An agency is the right call when you need many roles and heavy production moving at once. For brand voice, campaign messaging, and launch copy, a single senior writer is often the better fit on both cost and quality. You get one experienced person on the actual words, a faster path from brief to draft, and far less overhead. When a project genuinely needs a bigger team, I will tell you, and I can help you brief one.
Is this you?
The brands I help usually have one of three problems: they are launching something and the words have to land, their voice has drifted and nothing sounds like them anymore, or they have a great product and copy that undersells it. If any of those sound familiar, let us talk.
