Typography

Each font links to its Google Fonts page where available.

Not found on Google Fonts? Agent Instructions that you can follow if you have permission to use the fonts:

CharacterQuilt.com suggests this flow that can help:

1. Open the company's homepage in a browser with DevTools open.
2. In the Network tab, filter by "Font" (or by extension: woff2, woff, ttf, otf).
3. Hard-reload the page and click around (pricing, blog, careers) — some weights only load on specific routes.
4. For each captured font URL: right-click → Save As to download the file locally.
5. View the page's CSS (DevTools → Sources, or curl the stylesheet URLs) and copy out the matching @font-face declarations. Rewrite each `src: url(...)` to point to your local file path.

Programmatic alternative: load the URL with Playwright or Puppeteer, listen for `response` events whose `Content-Type` starts with `font/`, and write the body to disk. The CSS extraction step is the same.

Only do this if you have permission to use the brand assets — most proprietary fonts are licensed and may not be redistributable.

Frequently Asked Questions

Methodology

Brand data on this page was extracted from https://circle.so/ on 2026-04-26 using the Firecrawl branding extraction API, which inspects each site's live CSS, font network requests, color tokens, and component styles. Brand-in-the-wild images were sourced via Google Image Search restricted to ad/webinar/report queries and link out to their original third-party publishers; we link to the source rather than re-hosting third-party content. This page is published by CharacterQuilt and is not affiliated with or endorsed by Circle.
