Brand system and website by Plumage for the founder's Sirius. The mark and the wordmark are the founder's design. Part of [Our work](https://plumage.studio/work) by [Plumage](https://plumage.studio).

Tagline: "Your orbit. Your future."

## Introduction

Sirius is a bank for a generation that is building more than a balance: one calm app for an account, savings and a card. Zenith is the name of its metal card. The bank, the logo and the app always say plain “Sirius”; ZENITH appears only on the card and wherever the card is shown.

The mark and the wordmark are the founder’s. The mark is four leaf shapes turned around an X, crossed by one gold orbit; the wordmark sets SIRIUS in open capitals with a star over the i. Plumage redrew both flat for print and screen, added a small cut that holds at 16 px, and kept the founder’s glowing render for heroes and imagery only.

Sirius is the brightest star in the night sky, the one people steered by. The bank should feel like that: a fixed point on a dark night. Night grounds, white forms and one gold light, said in calm, exact words; never space opera, crypto glitter or “next-gen” hype.

## Marks

The mark comes first and SIRIUS follows it, in the founder’s proportions. Use the lockup wherever there is room; the mark with its orbit where it stands alone and large; the small cut, with no orbit, for the app icon, the favicon and anything under 48 px. The star over the i is the wordmark’s only gold. Never add glow, metal or gradients to the logo files, never rotate the mark (the X must stay an X), and never retype the wordmark in Sora.

## Voice

Sirius speaks like a calm private banker who explains everything in plain words: exact, warm and brief.

It tells people what happened, what it costs and what they can do next, in that order. Money is never a game and never an emergency.
