Frequently asked
Common questions.
What does a B2B content partner actually do?
Owns the content function inside your team. Strategy, voice, production, and distribution — end to end. The role replaces the coordination overhead of an agency and the headcount cost of a full-time senior hire. Most engagements run alongside an existing marketing lead or founder, not above them.
What's the difference between Founder LinkedIn and a Fractional Content Operator engagement?
Founder LinkedIn is a productized service that runs a founder's LinkedIn presence — voice profile, cadence, analytics, all of it. Fractional Content Operator is the full content function for a B2B company — articles, newsletter, sales enablement, audits, AI workflows. You can have either, or both.
What B2B verticals do you work with?
B2B SaaS, tech, AI, ed-tech, fintech, and IoT — broadly, founder-led companies between 10 and 100 employees where content is one of the channels that has to work. Past clients include Nexxiot, Kritik, Classet, TeachFront, and the Government of Ontario.
Do you work with clients outside Toronto?
Yes. The work is remote-first. Toronto is the home base; engagements run with B2B companies across Canada, the United States, and Europe. In-person sessions and video shoots are available for Toronto-based clients.
