Built for teams and researchers who can't afford work that doesn't hold up.

Markup Editorial is a writing and editorial firm working across three disciplines: technical documentation for software and infrastructure teams, academic and book editing for researchers and authors, and SEO content for brands that need to rank and convert.

We operate as a collective of specialists, each engagement handled by the person best suited to the work, to a shared standard, with full accountability to the client.
