Genesis Site Design
Genesis is a marketing-intelligence B2B SaaS platform that must look credible to enterprise buyers, investors, and future partners; whilst also signalling hands-on delivery capability (a consultancy/agency layer) without feeling like a traditional agency site.
This skill exists because most coding outputs nail components but fail the thing buyers actually feel first: layout, hierarchy, and narrative.
Scope
Use for
- •Marketing website pages (home, product, platform, pricing, resources, case studies, company, careers, legal)
- •Section systems, page templates, content models, and sitewide design tokens
- •Responsive layout, motion, accessibility, performance, and SEO
Not for
- •Product UI (dashboards, admin panels, in-app flows). Use
/interface-design.
Success Criteria
A Genesis page is "professional" when it:
- •Reads like a confident, specific product; not a general agency
- •Demonstrates proof (numbers, logos, case studies, methodology, security posture)
- •Feels intentional on mobile and desktop (type scale, spacing rhythm, grid)
- •Loads fast, passes Lighthouse, and is accessible by default
If another model could produce the same site from a generic prompt, the work failed.
Multi-Agent Workflow (Required)
You will run 6 specialised agents (as internal roles) and then synthesise.
Agent 1: Competitive & Reference Analyst
Goal: Extract patterns from high-performing B2B SaaS + digital consultancies. Must produce:
- •12 references split into two buckets:
- •SaaS product excellence (e.g., Stripe, Linear, Vercel, Datadog, Notion, Webflow, Figma)
- •Consultancy/neo-consultancy excellence (e.g., Thoughtworks, Accenture Song, Deloitte Digital, BCG X, frog, AKQA, Work & Co)
- •For each reference: 3 "borrowable" layout moves + 1 thing to avoid.
Agent 2: Information Architect
Goal: Decide the site map, page purposes, and content model. Must produce:
- •Site map (top-level + 1 level deep)
- •A reusable section inventory (15–25 sections) with intent, inputs, and variants
- •A "proof ladder": what evidence appears at each scroll depth (above the fold → footer)
Agent 3: Brand & Visual System Designer
Goal: Create the visual language so Genesis is memorable and not template-ish. Must produce:
- •Type system (display + body + mono; with fallbacks)
- •Colour system (tokens, light/dark, semantic states)
- •Layout system (grid, container widths, spacing scale using rem + occasional px for hairlines)
- •A single "signature motif" (unique to Genesis) that appears in multiple places
Agent 4: Copy & Narrative Editor
Goal: Make the site read like a product that ships outcomes. Must produce:
- •One-sentence positioning
- •Hero headline + subhead + 2 CTA options
- •3 message pillars with proof hooks
- •"Neo-consultancy without agency cringe" rules (ban vague claims; prefer concrete mechanisms)
Agent 5: Interaction & Motion Designer
Goal: Motion that signals craft, not gimmicks. Must produce:
- •Page-load choreography (stagger; <600ms total feel)
- •Scroll-linked moments (sparingly)
- •Hover/focus micro-interactions
- •Reduced-motion plan (prefers-reduced-motion compliance)
Agent 6: Frontend Systems Engineer
Goal: Make it production-grade. Must produce:
- •Stack recommendation (default: Next.js + TS + Tailwind or CSS Modules + MDX/content layer)
- •Component architecture (section-first, not component-first)
- •Performance plan (image strategy, font loading, code splitting)
- •Accessibility checklist (WCAG basics, keyboard, focus, contrast)
The Genesis "Dual Identity" Rule
Genesis must look like:
- •A platform that compounds intelligence (SaaS credibility)
- •A delivery engine that applies that intelligence (consultancy credibility)
Do not mash them together. Use a two-lane narrative:
- •Lane A (Product): platform capabilities, data, workflows, integrations, security
- •Lane B (Delivery): programmes, enablement, onboarding, playbooks, outcomes
Each lane gets:
- •Dedicated sections
- •Dedicated pages
- •Dedicated proof (case studies split by "platform-led" vs "programme-led")
Page Templates (Minimum Set)
- •Home – positioning, proof, platform overview, outcomes, CTA
- •Platform – how Genesis works (data → intelligence → action), architecture diagram, integrations
- •Solutions – by role (Marketing Lead, Growth, RevOps, Founder) and/or industry
- •Case Studies – problem, approach, artefacts, results, timeline, quotes
- •Pricing – simple tiers + enterprise contact; show what's included; procurement-friendly
- •Resources – blog, reports, benchmarks, templates (lead capture without spam energy)
- •Company – mission, values, operating principles, security/compliance stance
- •Careers – talent brand, working style, benefits, interview process
- •Legal – privacy, cookies, terms (boring but immaculate)
Section System (Design for Reuse)
Design pages as compositions of high-quality sections (not random components). Every section must declare:
- •Purpose (what decision it helps the buyer make)
- •Inputs (copy, stats, logos, screenshots)
- •Variants (short/long, light/dark, media-left/right)
- •Responsive behaviour
- •Accessibility notes
Examples of required sections:
- •Hero (two CTAs + trust strip)
- •"How it works" (3–5 steps with a visual narrative)
- •Product screenshots with annotated callouts
- •Methodology / framework (Genesis' distinctive model)
- •Proof grid (metrics, logos, certifications, press)
- •Case study teaser cards
- •Comparison table (Genesis vs status quo)
- •Security & compliance (plain language, not legalese)
- •Integrations strip
- •Founder note / vision (optional; keep factual)
- •Primary CTA section (no generic "Let's talk")
Professional Aesthetic: What to Copy from the Japanese References
From strong Japanese B2B agencies/consultancies, pull these patterns:
- •Clear top navigation with restrained density
- •Above-the-fold clarity: what they do + who for + proof
- •Case studies treated as first-class (not "portfolio vibes")
- •Big-number evidence blocks (volume, years, outcomes)
- •Calm spacing, disciplined grids, and careful typography
- •Frequent but tasteful CTAs (資料請求 / お問い合わせ patterns translate well)
Avoid:
- •Overly decorative hero art that says nothing
- •Stock-photo "smiling meeting" clichés
- •Endless service tiles with identical blurbs
- •Random border radii, shadow styles, and spacing values
Layout-First Rules (Non-Negotiable)
- •Start with page maps: draw boxes before styling.
- •Establish grid + spacing rhythm (rem-based): e.g., 0.25rem steps or a 4px equivalent.
- •Define content widths: readable measure for text; wider for visuals.
- •Only then design components to fit the layout system.
If layout isn't decided, do not code.
Implementation Rules
Units & Responsiveness
- •Use
remfor spacing and type; allow px only for hairlines, icons, and exact media borders. - •Mobile-first; no desktop-first "shrink to fit".
- •Use fluid type (
clamp) for hero and section headings.
Typography
- •Two-font system: expressive display + disciplined body.
- •One monospace for data/metrics.
- •Tight tracking on headings; generous line-height on body.
Colour
- •One dominant brand hue + one sharp accent; everything else is structural neutrals.
- •Semantic colours have purpose (success, warning, destructive).
- •Dark mode is not an afterthought; it is a first-class theme.
Motion
- •Prefer CSS for simple interactions; use a motion library only when it adds clear value.
- •Respect reduced motion.
- •One or two "hero moments" beat constant animation.
Proof & Trust
B2B buyers need:
- •Logos (curated, not a wall)
- •Metrics with context (timeframe, baseline)
- •Named frameworks / methodology (not buzzwords)
- •Security posture page (SOC2 roadmap, data handling, SSO, RBAC — say only what's true)
Performance
- •Use modern image formats; responsive sizes; lazy-load below the fold.
- •Self-host fonts; preconnect sparingly.
- •Avoid heavy third-party scripts; measure each one.
Output Requirements (What you must return)
- •Reference Digest: the 12-site reference list with "borrow / avoid".
- •Site Map + Section Inventory (with variants).
- •Design System Tokens: spacing, type scale, colours, radii, shadows.
- •One page fully specified (Home) as a layout blueprint:
- •Section order
- •Copy placeholders
- •Proof placement
- •Component requirements
- •Only then: production code (Next.js preferred) implementing the section system.
