How to build a scalable B2B software website with a design system and Claude

Before the framework, understand which scenario applies to your team. They require different solutions.

Scenario one: you have a designer or design agency on retainer. Your team produces custom designs for new pages. Quality is high. The bottleneck is that every new page requires a design brief, a design round, and a development handoff. Marketing moves slower than the business requires.

Scenario two: you do not have ongoing design access. Marketing is building pages from whatever Figma files exist. Quality drifts. Each new page looks slightly different from the last. The site loses visual coherence over time.

Both scenarios share the same root problem: no shared system. The fix is different for each.

If you have a designer or a design agency on retainer, the highest-leverage investment is building a proper component system first - then using that system as the foundation for everything that follows.

Here is how this works in practice.

Build in modular components from the start. When Weroast designs a website, every section is built as a named, documented, reusable component - hero, proof block, feature grid, testimonial strip, CTA. Each component is designed to work in multiple contexts, not just the homepage. When marketing needs a new feature page, they are assembling existing components in a new order, not commissioning new design from scratch.

This is exactly how we worked with one B2B software client. We built their homepage and design system together. Every page that followed - and they have shipped over twenty since - reused components from that system. The designer's time goes to genuinely new creative work: a campaign page that needs a new visual approach, a product launch page that needs a unique hero. Templated pages - blog, case studies, feature pages, use-case pages - are assembled by the marketing team from existing components and handed to a developer. No design brief required.

What this gives design-led teams:

• Repeatable marketing pages ship at the speed of copy, not the speed of design
• Designer time is reserved for genuinely creative work, not assembly
• Visual consistency holds across every page without policing
• A design agency retainer - multiple designers, subscription-based - gives you far more capacity per dollar than a single full-time hire, and the component system makes every hour of that retainer go further

The best design-led teams we work with use a retainer agency exactly this way: build the system once with Weroast, then use the retainer for new unique pages and campaigns. The templated pages handle themselves.

If marketing is building pages without a dedicated designer, the challenge is different. You need a system that lets a non-designer produce on-brand pages without guessing at visual decisions.

This is where Claude enters the picture.

Build the design system, then set up Claude as the scaffolding layer. When we deliver the Website + Design System + Claude Setup, the Claude configuration knows every component in your Figma library by name, what order components typically appear for different page types, your brand voice, tone, and vocabulary rules, and how to structure copy so it fits the visual system.

When a PMM needs a new comparison page, they open Claude, describe the page, and get a production-ready page scaffold - the right components, in the right order, with copy drafted to fit the visual structure. A developer drops the components in. The PMM fills the copy. The page looks like it belongs to the same site as every other page.

This is not a generic AI page builder. Generic builders produce pages that look like every other SaaS site. This setup produces pages that look like yours - because it was configured specifically for your component library and your brand.

What this gives marketing-led teams:

• New pages from brief to development-ready in hours, not weeks
• Visual consistency maintained without a designer in the loop for every page
• Marketing owns the page production process end to end
• The system gets more valuable as the component library grows

Whether you are design-led or marketing-led, the design system is the foundation. Without it, neither scenario works properly.

A design system is not a style guide. A style guide tells you which fonts and colors to use. A design system gives your team a library of production-ready components - sections, modules, interaction patterns - that can be assembled into new pages without reopening creative decisions that have already been made.

In practice, this means:

• Your homepage uses a hero, a proof block, a feature grid, testimonials, and a CTA strip
• Those six components exist in Figma as named, documented, responsive modules
• When marketing needs a feature page, they assemble four of those components in a new order and swap the copy
• The page is visually consistent with every other page on the site without a single new design decision

The Figma design system Weroast builds includes color, typography, and spacing tokens; all component states (default, hover, active, disabled); responsive frames at five breakpoints; interaction and animation notes; and named components that match the Claude configuration.

This is the difference between a marketing team that ships two new pages per quarter and one that ships twenty. The bottleneck is almost never copy or strategy. It is the gap between "we need this page" and "the page is live."

Claude solves the scaffolding problem that a Figma component library alone cannot.

When a marketing team member needs a new comparison page, they face two challenges:

• Which components to use and in what order
• How to write copy that fits the visual structure of those components

A custom Claude setup removes both. The configuration maps your component library, your design tokens, your section names, and your brand voice into Claude instructions. When your PMM asks for a comparison page, Claude knows which sections your library includes, what order they appear in for that page type, and how to structure copy so it fits the visual system.

The output is a scaffold - not a finished page. Your developer drops the components in. Your PMM fills the real copy. The creative decisions are already made. The brand identity is already documented.

This is not a replacement for a designer. It is what makes the hours of design work you already invested compound across every future page.

Here is how the Website + Design System + Claude Setup delivers these two scenarios in one engagement.

Phase one - the website (days one through fourteen): The website is scoped pages-based. Every page type your team will need in the next twelve months is mapped and designed in the Signature Design Style - homepage, feature pages, use-case pages, blog templates, case study templates, inner pages. Each page is designed as modular components, not as a one-off layout.

Scope the system around the page types the team expects to ship over the next twelve months, not around an arbitrary component count. The useful measure is whether marketing can assemble the next real page without reopening the design process.

Phase two - the design system and Claude setup (days fourteen through twenty-one): Every component from the website is documented in Figma with tokens, states, and responsive frames. Claude is configured with your component library, section naming, and brand voice rules. At handoff, your team receives:

• Figma files for every page
• A full component library with documentation
• Claude configuration ready to scaffold new pages
• Instructions for both scenarios - design-led and marketing-led

What gets built next is up to your team. Design-led teams use the components as the foundation for new unique pages the designer creates. Marketing-led teams use the Claude setup to scaffold templated pages independently. Both teams ship more pages, faster, in the same visual language.

This system is built for B2B software and AI companies that:

• Have proven their homepage message in market and know the next twelve months require a pipeline of feature, use-case, comparison, and campaign pages
• Want to give marketing the ability to ship templated pages without a design queue for every brief
• Understand that a design system built once compounds across every future page - and that this is how companies like Stripe, Linear, and Attio maintain visual consistency at scale

The typical starting point is a PMM or head of marketing who has been waiting weeks for routine pages and knows the bottleneck is architecture, not effort.

Wait if your homepage message is still being tested. Building a 15-component system around a hero claim that might change in three months is expensive. Start with the homepage sprint, prove the message, then build the system.

Wait if your ICP is still unclear. If three people on your team describe your ideal customer differently, a design system will be built around conflicting inputs. Fix the positioning first. The website redesign prerequisites guide has the specific litmus tests.

Wait if you are pre-PMF. A component system assumes a stable product story. Read pre-PMF website design for the honest guidance on when design investment makes sense at each stage.
