About

A 25-year-old name. A new kind of practice.

The name goes back 25 years. My mom, Nora Camps, founded DUO Strategy & Design and spent two decades building brand and communications programs for hospitals and universities across Ontario. Print-led, slower, more deliberate work.

In 2021 I asked to revive the name and make it my own. DUO relaunched as a B2B content marketing practice. Senior content work for tech startups across North America and Europe.

Today DUO runs Founder LinkedIn: a managed system that turns founder thinking into a consistent LinkedIn presence (voice, production, publishing) with AI in the production layer and the judgment kept human.

Who you work with

I’m Justin. You work directly with me.

I run DUO and lead every engagement myself. The calls, the writing, the review. When DUO manages your LinkedIn, I’m the one who interviews you, writes in your voice, and keeps your calendar publishing. No junior layer, no account manager.

The hard decisions come before anything gets written: what’s worth saying, why it matters, who needs to hear it. That’s where I spend the time. AI makes production faster. It doesn’t make that call.

Milestones

How I got here.

01

Political communications

Three years in government and political communications, helping manage a politician’s personal brand. A public voice, under real scrutiny, published at a constant cadence. That was ghostwriting before I knew to call it that.

Careful, risk-managed stakeholder messaging one week; collaborations with MLSE, Apple, Rogers, Kids Help Phone, and school boards the next.

Before that, classroom teaching in Toronto: the original training in making complicated things land.

02

The startup years

Eight-plus years of B2B marketing across SaaS, IoT, ed-tech, and AI. Some of it in-house, the rest working directly with founders across Canada, Europe, and the United States.

Different companies, same pattern: technical, useful products that were hard to explain, and a founder whose own thinking was the clearest explanation the company had. Learning to find that thinking and get it published is what DUO is built on.
