Using the logo

Clear space, the smallest it may go, and the six things that break it. Each pair below is the real lockup, correct on the left and wrong on the right.

X X
Clear space Keep the height of the mark clear on all four sides. Nothing crosses that line, including the edge of the page.
150px minimum for the lockup
28px for the mark alone. Below that, use the mark, never the lockup

Imagery

Marbling is material where Airmond is photographic. Everything is cut from the two slabs, never generated fresh, so the same stone runs through every surface.

Applications

The brand on the surfaces people meet it on. Shaded areas are where each platform stamps its own avatar or crops: measured against live pages by gtm/social-profile-assets, not taken from a published guide. The downloads are the clean files without the shading.

Writing the name

  • Marbling, one word, capital M. The legal entity is Marbling AG, Freienbach SZ, Switzerland; its English rendering is Marbling Ltd., never “Inc.”, which would wrongly imply US incorporation. Use the full form once in a document, then Marbling.
  • The five parts are Airmond, Tartare, Latch, Arena and Metal. All five take a capital, including Metal.
  • The five parts are not equals in public. Airmond is the live product and the only one with a domain of its own, airmond.com; the other four sit on marblinghq.com subdomains. Latch and Tartare run our own fleet, Arena and Metal are alpha. Those three words — live, runs our own fleet, alpha — are the whole status vocabulary; do not invent a fourth, and do not present an alpha as shipped.
  • Marbling runs an engine; it does not make tools. One engine, five parts, is the sentence everything else hangs off.
  • Lowercase marbling only in a domain, handle or repo name: marblinghq.com.

Boilerplate

The approved words. Paste them into a profile or a page as they are: a second description of the company is how a brand starts disagreeing with itself.

One-liner39 characters

One engine runs every company we build.

The single sentence. Site hero, X bio, a tagline field.

Short description144 characters

Marbling builds and runs Airmond, Latch, Tartare, Arena and Metal: one engine in five parts, run by a small team and a large fleet of AI agents.

LinkedIn tagline, a directory entry, a card.

About447 characters

The team is deliberately small. Most of the work is done by agents. They hold the context, do the drafting and the calling, and carry the parts of a company that used to need a department. The engine is one codebase, so when one product learns something every product gets it in the same release. That makes each new product a question of distribution rather than a new company: a different audience, a different name, the same engine underneath.

LinkedIn About, an About page, a press boilerplate.
