Ways to work with DUO
Brand Content Leadership
A senior content operator leading brand content from planning through publishing.
We turn founder thinking, customer insights, and market perspective into published work that builds authority, earns trust, and gives your company a stronger voice in market.

A managed LinkedIn system that turns your ideas, perspective, and voice into consistent posts across written and mixed-media formats.
2–3 hours from you each month. 2–3 posts a week.
See how it works →One senior operator to run brand content.
From strategy, production, and judgment. I work with your existing creatives and marketers, or operate solo for lean teams. Content is the bridge between you and your audience. I make sure your voice and value come through consistently, and with precision.
One owner, fully accountable
Not a junior, not an agency at arm’s length. One senior operator owns the whole function, end-to-end.
Content that builds authority
Senior editorial judgment on every piece, so the work earns trust and shortlists, not just impressions.
Senior content capability, without the full-time hire
AI helps with volume and workflow. Senior judgment owns the message, quality, and final work.
The LinkedIn System for Founders & Execs
Live extraction, AI workflows, and senior editing turn your ideas into a consistent LinkedIn presence. You give 2–3 hours a month. We handle the system, production, and publishing for 2–3 posts a week.
Turn founder thinking into market visibility
Your perspective is already showing up in sales calls, customer conversations, and internal decisions. We turn it into content your market can actually see.
Stay consistent without adding another job to your week
You give 2–3 hours a month. We run the extraction, writing, editing, production, and publishing system.
The reach only a founder has
Buyers trust the person before the brand. Your voice becomes the channel that pulls them in.

I'm Justin. I run DUO as a senior content partner for B2B founders and teams.
I've spent eight years working with B2B teams across SaaS, IoT, ed-tech, and AI, plus a few years in government communications.
The work usually takes one of two forms: Brand content leadership run end-to-end, or a focused Founder LinkedIn system.
AI helps with speed and structure. Judgment, message, and craft stay with the operator.
Writing from inside the work.
All writing →
LinkedIn ghostwriters, agencies, and tools for founders, compared honestly
Eleven services and three tools for founders who want LinkedIn run for them, compared by model, not marketing copy. The split that matters is input capture: services that extract your actual thinking produce content that sounds like you. Tools solve scheduling and formatting, not the writing.
B2B content marketing agencies for startups: 5 strong ones, and when not to hire any
Five established B2B content agencies compared by what they're actually built for, plus the question most roundups skip: whether an agency is the right shape at your stage. The common startup failure is buying agency output when the real gap is someone senior who owns the system.
Why your AI content sounds generic (and the voice-spec fix)
AI content sounds generic because the model has nothing telling it how you specifically write. Brand-voice adjectives ('confident, conversational') don't help. A documented voice spec, built from patterns and used as system prompt input, does.
