Before

The logo was a rounded square with a gradient.

Horizon's pitch deck used a rounded square filled with a gradient as its logo. It was a placeholder: it looks like many AI tools, it disappears at favicon size and it does not work in one colour. The product needed a face of its own.

What I found

The product already had an idea in it.

Horizon answers why code is the way it is. The question you ask today sits above a line. The history sits below it: commits, reviews, issues and people who left. That became the whole identity: one horizon on every page.

What I built

One idea, called Dawn

The logo is that idea in miniature: a sun rising behind a horizon line, held inside two brackets, the way a source is cited. Around it we built the full system: four logo lockups in six colour versions, colours that read as sky above and earth below, two typefaces, a plain voice, an icon set, a favicon and app icon, an email signature and the brand book.

What changed

A brand the team can use straight away.

Horizon now has one recognisable mark that works from a favicon to a presentation cover, a colour and type system with clear rules, and a brand book that says what not to do. The same identity runs through the website and through the pitch decks, in English and Romanian.

This works if you

  • You have a product but no identity beyond a placeholder
  • You want logos, colours and rules you can hand to anyone who builds with them

It is not for you if

  • You want a logo only, with no system behind it
  • You cannot give feedback while the directions are narrowed down
