How to present Castanet Buzz
The name, logo, colours and voice — for press, partners and anyone who writes or designs something about us. Everything here is free to follow; the logo kit is one click away.
What Castanet Buzz is
Castanet Buzz is a structured discovery and communication layer between startups and investors — subscription-based listing, intent and conversations.
Mission
Give founders a structured, living pitch and investors a private, filter-first way to discover, follow and engage — so every interaction is more transparent, contextual and actionable.
The mechanic
Follow to reveal. Investors browse anonymously and share their identity only when they follow. Identity follows intent, not the other way around.
What it is not
Not a marketplace and not a fundraising platform. We do not execute investments, hold escrow or move capital, and nothing on our site is an offer or solicitation.
The name
A castanet is two shells that make a sound only when they come together. That is the platform: startups and investors each bring their half, and the moment they connect — the follow — is the sound.
A castanet also marks rhythm, precision and signal: structured, intentional engagement at the right moment, not spray-and-pray outreach. The .buzz domain is that signal.
In writing, always “Castanet Buzz”
Two words, both capitalised. Please don’t shorten it to “Castanet” — on its own it reads as the instrument or gets confused with other companies.

Logo
The mark is a double-swoosh glyph and the wordmark spells CASTANET in a condensed all-caps face. Use the teal files on light backgrounds and the white files on dark or teal backgrounds. All files are PNG, supplied as masters.
On light backgrounds
On dark and teal backgrounds
Clear space and minimum size
Keep a margin of x on every side, where x is the height of the capital letters in the wordmark. Keep other logos, text and image edges outside it.
| File | Screen | |
|---|---|---|
| Lockup | 120 px wide | 25 mm wide |
| Wordmark | 80 px wide | 18 mm wide |
| App icon / mark | 24 px square | 6 mm square |
Below these sizes the fine inner strokes of the mark fall under a pixel and the logo turns soft. Scale proportionally: the wordmark is a 10:3 image, so set a width and let the height follow.
Do
- Use the files as supplied, scaled in proportion.
- Use white files on dark, teal or photo backgrounds.
- Use the app icon tile where a square icon is needed.
Don’t
- Recolour, outline, stretch, rotate or add effects to a logo file.
- Retype the wordmark in a font — it is an image.
- Put the teal logo on a dark background, or the white logo on a light one.
- Imply that we endorse, sponsor or partner with you without our agreement.
Press, partners and publications may use the logo files to refer to Castanet Buzz. For any other use, contact us first.
