IBM Plex Mono. Every headline, every body paragraph, every label, every log line, the logo itself. One typeface, seven weights, no exceptions. The decision that looked like a limitation and turned out to be the brand.
The Qann brand uses one font.
IBM Plex Mono. Every headline. Every body paragraph. Every navigation link, every label, every data value, every terminal line. The logo itself. <qann>. Is that same typeface, weight 700, with angle brackets that turn it into something that looks like it was typed into a terminal. Because it was.
No display font for headlines. No serif for long-form reading. No sans-serif for UI. One font. Seven weights. That is the entire typographic system.
When we tell designers this, the first reaction is usually concern. When we tell founders, the first reaction is usually: "is that enough?"
The answer, after building an entire brand on it, is yes. More than enough. And the reason why tells you something useful about how brand identity actually works.
The conventional approach to brand typography is a pairing. A distinctive display font for headlines. Something with personality, something that catches the eye. And a readable workhorse for body text. Maybe a third for UI elements. This is sensible advice and it produces sensible results.
The problem with sensible results is that they are forgettable.
A font pairing, done well, is invisible. It does its job. Text is legible, hierarchy is clear, nothing feels wrong. You leave the website without remembering anything about the type. That is considered success. For most brands it probably is.
But the brief for Qann was not invisibility. The brief was a brand that felt like it was built by someone who actually runs businesses. Technically precise, no decoration for its own sake, honest about what it is. A brand that looked like a terminal output rendered on warm paper. When we asked what typeface that was, the answer was obvious: a monospace font. One that was designed with technical confidence rather than typographic elegance as the goal.
IBM Plex Mono was designed by Bold Monday for IBM. It was built to work in code editors, documentation, and terminal interfaces. It was not designed for branding. That is exactly why it works as branding. It carries associations that no amount of art direction could fake: precision, technical seriousness, systems thinking. Every character is the same width. Nothing is decorative. Every weight is useful.
The constraint of using it for everything. Body copy, headlines, UI, the logo. Is what makes those associations stick. If we used it only for the code-looking elements and switched to a humanist sans for body text, the technical personality would be a costume. Using it everywhere makes it a character.
The honest answer is: visual range.
A single monospace font cannot do what a well-chosen display face can do. It will not give you the warmth of a humanist serif or the neutrality of a geometric sans. At large sizes, monospace text has a specific texture. Even, mechanical, structured. That is arresting when it is right for the context and awkward when it is not.
We also lost the ability to use type weight and style contrast as the primary tool for hierarchy. In a typical system, you might distinguish a headline from body copy by switching to a display font entirely. We distinguish them with size and weight alone. 700 for headlines, 300 for body, the scale doing the work instead of the face change. This requires more care. Get the scale wrong and everything collapses into the same visual plane.
Body copy in a monospace font also reads slightly slower than in a proportional face. The even character spacing that gives it its technical personality is the same thing that makes long-form reading marginally more effortful. We compensate with generous line height and a warm cream background that reduces eye strain. It works. But it required attention.
Everything else.
Consistency without rules. When there is only one font, there are no decisions to make about which font to use. Every designer, every AI tool, every template, every document produced by anyone at Qann uses the same typeface by default. Not because there is a rule saying to, but because there is no alternative. Constraint is the rule. You cannot violate it by accident.
Coherence across contexts. The logo and the body copy and the code blocks and the navigation links and the data labels all share a typographic DNA. The brand does not feel like a collection of decisions made at different times by different people. It feels like one thing, made by one mind, for one purpose. This is very difficult to achieve with a multi-font system. It is almost automatic with one.
Personality that accumulates. The first time someone sees IBM Plex Mono used this way, it reads as technical. The third time, it starts to read as Qann. The tenth time, it is unmistakable. A single typeface, applied consistently across every surface, builds recognition faster than a complex system because there is only one thing to recognise. The brand is the font as much as it is anything else.
Freedom in layout. When you remove font-choice as a variable, other things become clearer. Spacing. Colour. Hierarchy through size and weight rather than face. You start to see the layout more clearly because one entire category of decision has been removed. The constraint opens up attention for everything else.
We use this project as a case study in something we try to tell clients: brand identity is not addition. It is subtraction.
The instinct, especially for a new brand, is to make choices. This font for this, that colour for that, this style for this context. The result is usually a brand that feels busy and inconsistent. Not because the choices are bad, but because there are too many of them.
The brands that are most recognisable have usually made fewer choices, not more. They have found the one thing that carries the personality. A typeface, a colour, a structural pattern. And applied it with enough commitment that it stops being a design element and becomes an identity.
For Qann, that thing is IBM Plex Mono. The logo is typed in it. The body copy is set in it. The terminal language that runs through the site. The // section tags, the $ commands, the object.property = value data lines. All of it legible in the same face, because the same face is the brand.
It looked like a limitation. It turned out to be the whole point.
the brand bible for qann.co specifies IBM Plex Mono at weights 300, 400, 500, 600, and 700. the logo is weight 700. body copy is weight 300 or 400. the font is available free at fonts.google.com.
