A set of sidebar add-ons for Slides, Docs, and Sheets that keep any document on-brand automatically. The core problem: Google Workspace has no native way to use a custom brand typeface — Samsara Sans isn't a font Google Slides, Docs, or Sheets can access, so every deck and doc defaulted to a generic system font, and true brand consistency was structurally impossible without manually pasting in images or asking people to install fonts locally. Brand Kit solves this by embedding Samsara Sans directly into the tool itself, making an unsupported brand typeface finally usable — alongside auto-fitting cover text, one-click color swaps, a shared 200-icon library, and chart theming in Sheets via the Sheets API. Used by 1,428 people company-wide, running 7,860 times at a 0.15% error rate. Samsara's CMO called it out directly as "our next big opportunity" for scaling the brand.
