Hi, I'm Mariah.

Brand narrative specialist. Strategist and writer. Partner to women-led brands.

I've spent almost a decade at Fortune 100 companies, an AI startup, and most recently the leading global technology company. In that time I've brought brands into the world through marketing strategies, content, campaigns, and partnerships.

What I noticed across all of it is that the brands that resonated weren't always the ones with the biggest budgets or the most polished decks. They were the ones where the founder's voice or vision stayed intact — where there was a tangible bridge between the strategy and the story that got told. Most brand work breaks as these two crafts diverge. The work I do is the bridge.

About Seaworth

I built Seaworth to help you show the world your vision, as you see it.

My work sits at the intersection of three things most brand consultants treat as separate:

Strategy
The foundation that makes a brand defensible
Narrative
The writing that makes a brand real to the people it's for, wherever it might show up
Voice
The specificity that gives a brand a true personality, rather than just sounding like every other company in a category

Most strategists outsource the writing. A lot of writers don't do strategy. Most voice work happens in isolation from both. I absolutely love being able to uniquely offer all three.

I take on a limited number of engagements at a time, seeking clients whose work is too specific to sound like everyone else and who deserve a brand that reflects the story it comes from.

What I believe

01

Brand voice is not optional.

The way a brand sounds isn't a finishing touch. It's one of the most strategic decisions you can make. It determines who's drawn in, who self-selects out, whether the work feels real or generic.

02

Strategy AND writing.

While they should build off of each other, most brand work breaks because of the handoff. Blending the work of the two creates a coherent brand experience.

03

Specificity wins.

When you say everything, you say nothing. The more specific and honest the language, the more powerfully it will land with the audience it's meant for.
