The logo, in blackand in white.
Everything needed to put TWENTYONE on a page, a slide or a screen: the logo in both colours, as transparent PNGs and as ready-made JPGs, and a short guide to using it well.
01 — The story of the name
Why TWENTYONE.
When we founded the company, we didn’t want a generic tech name or a passing trend. We wanted a name rooted in the very core of computer science, mathematics, and pure logic. That is how we chose TWENTYONE.
In mathematics and algorithmic design, 21 is a Fibonacci number — part of the sequence that represents perfect growth, optimization, and structural harmony. But more importantly, in binary code, the language that powers all software, the number 21 translates to a flawless, alternating pattern: 10101.
For an engineer, 10101 represents clean architecture, symmetry, and ultimate efficiency.
We named our company TWENTYONE because that is exactly what we deliver. We take complex, heavy enterprise requirements and translate them into elegant, high-performance custom software. We don’t just write code. We build the perfect digital sequence to scale your business.

02 — Downloads
Two versions, two colours.
Transparent PNGs go on top of anything. The JPGs carry their own background, for the platforms that flatten transparency to black.
Logo with descriptor
The primary version. Use it wherever it can be shown at 200 px wide or more.
Wordmark only
For small sizes, favicons-in-context, social avatars and tight spaces, where the descriptor line would be too small to read.
03 — How to use it
A short guide.
Six rules. If a layout makes one of them hard to keep, the layout is the thing to change.
Black on light, white on dark
Use the black logo on white, ivory and light photographs; the white logo on black, dark colours and dark photographs. Pick whichever gives the stronger contrast — never a grey or tinted version in between.
Give it room
Keep a clear space around the logo at least half as tall as the letters of TWENTYONE on every side. Nothing — text, edges, other logos — enters that space. The downloaded files already include it, so align to the edge of the file, not the edge of the letters.
Mind the minimum size
The logo with descriptor: no smaller than 200 px wide on screen or 50 mm in print. Below that the descriptor line stops being legible — switch to the wordmark only, which holds down to 100 px or 25 mm.
Use the files as they are
Always start from the files on this page. Don't trace them, rebuild the logo from a font, or crop it out of a screenshot of the website.
Write the name correctly
In text, the name is TWENTYONE — one word, capital letters. Not “Twenty One”, “Twentyone”, “21” or “Twenty-One”. The website is twenty-one.co, with the hyphen; the name is not.
Beside other logos
In a row of partner or client logos, match the TWENTYONE wordmark to the optical height of the others, not its width, and keep the clear space from rule 2 between them.
Please don't
- Recolour it. The logo exists in black and in white — no brand colours, gradients or tints.
- Stretch, squash, rotate or skew it. Scale it only proportionally.
- Add shadows, outlines, glows or any other effect.
- Retype it. The letters are artwork; setting “TWENTYONE” in another typeface is not the logo.
- Rearrange the parts — move the descriptor, change its wording or set it beside the wordmark.
- Place it on a busy photograph or a mid-tone background where neither version reads clearly.
04 — Colour
Monochrome, on purpose.
The logo is only ever black or white. The website around it is ink on ivory, with no accent colour.
