Marker - the AI-native consultancy rebuilding businesses with AI agents opens with “Your AI transformation, actually shipped” in a left-aligned split hero. The homepage continues through 11 observed sections, moving from the opening proposition into You can see where this is going, The usual paths don't ship, AI agents that understand your company, then transform it. ## Color Contrasting light and dark surfaces use 7 repeated semantic colors; the primary action carries the strongest interactive emphasis. | Token | Value | Role | Usage | | --- | --- | --- | --- | | Canvas | `#000000` | Page canvas | Dominant rendered page background. | | Surface 1 | `#f6f6f6` | Surface | Repeated container or section fill; relative occurrence score 489. | | Surface 2 | `#1a1a1a` | Surface | Repeated container or section fill; relative occurrence score 204. | | Surface 3 | `#f7f7f7` | Surface | Repeated container or section fill; relative occurrence score 141. | | Primary text | `#333333` | Primary text | Observed display foreground; its canvas-reference contrast is 1.7:1 and may rely on a local hero surface. | | Secondary text | `#868686` | Secondary text | Observed reading foreground; measured canvas-reference contrast is 5.8:1. | | Action | `#ffffff` | Primary action | Fill used by the dominant first-viewport action. | ## Typography The observed type system assigns Stack Sans Headline to display, heading text; Inter to body, body-small, label text. | Role | Family | Size | Weight | Line height | Tracking | Style | Features | Color | | --- | --- | --- | --- | --- | --- | --- | --- | --- | | display | Stack Sans Headline | 56px | 400 | 67.2px | -2.24px | normal | none | rgb(51, 51, 51) | | heading | Stack Sans Headline | 64px | 400 | 70.4px | -2.56px | normal | none | rgb(51, 51, 51) | | body | Inter | 16px | 400 | 17.6px | -0.32px | normal | none | rgb(51, 51, 51) | | body-small | Inter | 12.5px | 400 | 18.75px | 0px | normal | none | rgb(107, 107, 107) | | label | Inter | 12px | 600 | 18px | 0.96px | normal | none | rgb(110, 110, 110) | ## Spacing and shape - Base unit: 8px - Density: sparse - Maximum content width: 1440px - Section gap: 32px - Container padding: 24px - Common spacing: `24px`, `32px`, `8px`, `12px`, `40px`, `20px`, `2px`, `16px`, `14px`, `7.5px` - Corner strategy: Soft geometry is the dominant shape voice. Elevation is selectively reinforced with shadow. - Radii: Pills `999px`, Containers `8px`, Cards `14px`, Buttons `14px`, Media `0px` - Borders: `1px solid transparent`, `1px solid rgb(230, 230, 230)`, `1px solid rgba(0, 0, 0, 0.102)`, `1px solid rgba(0, 0, 0, 0.078)`, `1px solid rgba(255, 255, 255, 0.102)` - Shadows: `rgba(0, 0, 0, 0.05) 0px 2px 6px 0px, rgba(0, 0, 0, 0.07) 0px 10px 24px 0px`, `rgba(0, 0, 0, 0.04) 0px 1px 2px 0px, rgba(0, 0, 0, 0.06) 0px 12px 32px 0px`, `rgba(0, 0, 0, 0.15) 0px 2px 3px 0px inset, rgba(0, 0, 0, 0.07) 0px 0px 8px 0px inset`, `rgba(255, 255, 255, 0.65) 0px 2px 0px 0px inset, rgba(255, 255, 255, 0.35) 0px 0px 0px 1px inset, rgba(255, 255, 255, 0.5) 0px 14px 24px 0px inset, rgba(0, 0, 0, 0.04) 0px -20px 32px 0px inset, rgba(0, 0, 0, 0.26) 0px 5.73px 5.73px 0px inset, rgba(0, 0, 0, 0.22) 0px 0px 20.62px 0px inset`, `rgba(0, 0, 0, 0.26) 0px 5.73px 5.73px 0px inset, rgba(0, 0, 0, 0.22) 0px 0px 20.62px 0px inset, rgba(0, 0, 0, 0.08) 0px 6px 24px 0px` ## Layout - Macrostructure: Split product narrative - Hero: Split hero: message and proof share the first viewport - Grid: 1 column - Footer: Index footer with 12 actions - Reading flow: The homepage continues through 11 observed sections, moving from the opening proposition into You can see where this is going, The usual paths don't ship, AI agents that understand your company, then transform it. - Section sequence: You can see where this is going → The usual paths don't ship → AI agents that understand your company, then transform it → What this looks like today → How Marker works → We’ve sat on every side of this → You'll know in thirty seconds → Manual work, down by 80%. → 2-time YC founders → 2 previous exits → Founded Gap's Office of AI ## Component grammar ### Hero Split, left-aligned opening anchored by “How it works”. - Role: Opening proposition - Observed instances: 1 - Pattern: `split` - Alignment: `left` - Heading: `Stack Sans Headline · 56px / 400` - Media: `image-led` ### Primary action “How it works” is the strongest first-viewport action by semantic intent and visual contrast. - Role: Conversion - Observed instances: 1 - Background: `#ffffff` - Text: `#1a1a1a` - Border: `1px solid rgb(230, 230, 230)` - Radius: `6px` - Padding: `13px 14px 13px 14px` - Type: `Inter · 14px / 500` ### Content card 4 style-matched content card instances were found among 14 candidates; properties describe the dominant observed cluster. - Role: Repeated content module - Observed instances: 4 - Background: `#ffffff` - Text: `#333333` - Border: `1px solid rgba(0, 0, 0, 0.102)` - Radius: `20px` - Padding: `0px 0px 0px 0px` - Type: `Inter · 16px / 400` - Candidate pool: `14` ### Badge or tag 4 style-matched badge or tag instances were found among 10 candidates; properties describe the dominant observed cluster. - Role: Compact status or category label - Observed instances: 4 - Text: `#6f6f6f` - Border: `1px solid transparent` - Radius: `999px` - Padding: `9px 32px 8px 32px` - Type: `Geist · 12px / 500` - Candidate pool: `10` ### Media frame 9 style-matched media elements were found among 14 rendered candidates; fill fitting and 0px are the most repeated treatments. - Role: Visual proof - Observed instances: 9 - Fit: `fill` - Ratios: `1.00, 1.79, 1.31, 2.91, 1.09` - Radius: `0px` - Candidate pool: `14` ### Footer 12 visible actions close the page on a #dde830 surface. - Role: Closing navigation - Observed instances: 1 - Background: `#dde830` - Text: `#333333` - Border: `none` - Radius: `0px` - Padding: `0px 0px 40px 0px` - Type: `Inter · 16px / 400` - Links: `12` ## Imagery Image led media acts as the page’s primary visual proof rather than decoration. A focused visual anchors the first viewport. - Inventory: 14 images/canvas elements and 0 videos across the analyzed homepage. - Treatment: fill fitting · square-edged frames ## Motion 12 declared keyframes and 40 active animations were inspectable at capture; observed timing uses 0.15s, 0.12s, 1s. - Libraries: CSS / browser-native or bundled source not identifiable - Durations: `0.15s`, `0.12s`, `1s`, `0.2s`, `0.14s`, `0.3s` - Easings: `ease`, `ease-in-out`, `ease, ease`, `ease, ease, linear, ease`, `ease, linear`, `linear`, `ease, ease, ease` - Interaction states: hover, focus, transition-all, disabled - Reduced-motion declaration found: yes ## Responsive behavior Measured at 390 × 844. - Mobile navigation presents 1 visible action versus 0 on desktop. - Hero alignment changes from left to center; mobile heading size is 44px. - 1 multi-column content region remains on mobile. - Horizontal overflow: not detected ## Do - Pair the observed #000000 canvas with #333333 primary copy before adding secondary surfaces. - Use Stack Sans Headline at 56px/67.2px, weight 400, for the primary display moment. - Reserve the strongest first-viewport contrast for “How it works” within the left-aligned split hero. - Image led media acts as the page’s primary visual proof rather than decoration. ## Don’t - Do not mix in arbitrary radii; 999px is the repeated treatment on pills. - Do not reuse the #ffffff action color across decorative elements; keep its interactive emphasis selective. - Do not introduce extra type families beyond Stack Sans Headline and Inter. - Do not copy transition-all declarations; keep only purposeful transform or opacity motion. ## Evidence - Hero: `/captures/marker/hero.webp` (960 × 600, scroll 0px) — Hero viewport evidence; animated text state captured. - Mid-page: `/captures/marker/middle.webp` (960 × 600, scroll 4519px) — Mid-page viewport evidence; animated text state captured. - Closing: `/captures/marker/closing.webp` (960 × 600, scroll 8817px) — Closing viewport evidence; animated text state captured. - Mobile: `/captures/marker/mobile.webp` (390 × 844, scroll 0px) — Mobile viewport evidence; animated text state captured. ## Confidence notes - The hero heading was read from semantic heading markup. - 12 responsive breakpoint declarations were inspectable. - 15 stylesheets were inspectable; 1 cross-origin stylesheet was unavailable to rule inspection. - Computed styles describe the captured render; source design tokens and proprietary font files were not copied.
