Does a Startup Need a Design System?

The short answer

Yes, but a small one. Once more than one person designs or builds, shared colours, type, spacing and components save time and keep the product consistent. A seed startup needs a starter kit, not a hundred-page system.

Design systems at a glance

• Seed: Colours, type, spacing and a dozen core components
• Series A: Documented components in Figma and in code
• Later: Tokens, variants, accessibility rules and an owner
• Sign you need one: The same button looks different on every screen

What a design system gives you

• Speed. New screens are assembled, not redrawn.
• Consistency. Product and website look related.
• Fewer bugs. Components are built and tested once.
• Easier onboarding. New designers and engineers get up to speed faster.

Start with

• Colour and type tokens.
• Buttons, inputs, tables and modals.
• Light and dark modes, if the product needs them.
• One place where it all lives.

Studio Huncho built the design system for the Rippl app, covering colour, type, iconography, illustrations and light and dark modes. See design systems.
