One operating system
The top-left corner is the dependable foundation: one calm place from which a business is run.
YionStack brand
One intelligent platform. Limitless possibilities.
Four corners. One core. The YionStack mark expresses a business operating as one connected system—every module distinct, every signal shared, and YionAI working across the whole.
The idea
Separate strengths. Shared purpose.
The pieces keep their own character, but their spacing and alignment make them read as one. That is YionStack: specialised capabilities without separate systems.
Intelligence in motion
The top-right corner is YionAI observing the whole business, connecting signals and acting with context.
Built for growth
Yellow brings optimism and momentum: clearer decisions, fewer seams and room to grow confidently.
Work completed
The bottom-right corner is the outcome: the module that turns connected information into finished work.
Why our logo matters
It is not a symbol. It is the architecture.
Every part of the mark carries a meaning we can be held to. If the product ever stopped working the way the logo describes, the logo would be the thing that was wrong.
The outer forms
Every capability a business runs on.
Finance. People. Customers. Operations. Projects. Communication. Education. Commerce. Every organisation weighs them differently, and the four forms stand for all of them rather than for any four in particular.
Each keeps its own shape. Each has its own responsibility. Not one of them exists alone — look at where they point.
The centre
The only solid shape in the mark.
Business identity. Trusted data. Permissions. Automation. Knowledge. Artificial intelligence. Context. The shared operating core that every capability reads from and writes to.
Take the centre away and the corners are four pieces of isolated software. Put it back and they are one operating system. That is the entire argument of this company, drawn at 16 pixels.
Read why we believe thisEverything revolves around the core.
One connected system
The core is the point.
Every corner connects to it. Information does not stop at a module boundary; it flows through the one operating system at the centre and returns as action.
- One customer record across every module
- One ledger behind every financial workflow
- One intelligence layer observing and acting

Colour
Confident foundations. Energetic outcomes.
Navy carries confidence; teal carries intelligence; amber and orange bring momentum and completion. Violet is the core they all connect to — and it is the product’s own primary, so the mark and the interface are literally the same colour. The wordmark uses only these two: violet for Yion, navy for Stack. Slate supports long-form communication.

Clear space
Let the system breathe.
Keep clear space around the mark equal to the width of one inner gap. Never crowd it with text, borders or another logo.
Minimum size
Clear, even when compact.
Use the mark at 16px or larger digitally. Below 32px, use the icon alone and keep the approved internal spacing intact.

The promise
Every corner of the business, working as one.
The mark is a reminder of what the product must always deliver: one source of truth, shared intelligence and real work completed across the whole business.
One system. One source of truth. Yion acts.
