flowmanceStartuo Design System
Startuo is a clean, friendly startup and SaaS site on a white page. It reads like a modern product landing page: compact Inter Tight headlines in weight 600, grey supporting text, small emoji-led violet eyebrows, and soft #F5F5F5 panels with 15px corners. Colour is limited to one violet (#7253F6). Everything else is black, white and greys. Imagery is either product UI (an engagement chart card, a phone with violet bar charts) or warm, calm team photography.
Four signatures make it recognisable:
- Emoji eyebrows. Most section titles have a small violet label above them, led by an emoji: 👋 Hey there! We're Startuo, 🚀 Who we are, 💬 Testimonials, 💵 Pricing.
- The hand-drawn underline. One word in a headline gets a violet marker-style scribble under it: business in the hero, organizations in the pricing title.
- Two-tone sentences. Lead lines start in dark grey and finish in light grey: Embark on a journey through our cutting-edge, resilient, then and lively Webflow template. in #888888. The "Who we are" statement does the same.
- Black buttons that flip to violet. The filled button is black with a 9px radius. On hover it turns #7253F6, and the round arrow buttons do the same.
Startuo is a light-only design.

Do’s and don’ts
- Put an emoji eyebrow in #7253F6 above main section titles (logo-strip and stats kickers stay grey).
- Use black #000000 for filled buttons and turn them #7253F6 on hover.
- Keep cards on surface-1 #F5F5F5 or white with a 1px #E1E1E1 border, always with a 15px radius.
- Split lead sentences into two tones: #444444 first, #888888 to finish.
- Underline one key word per headline with the hand-drawn violet scribble.
- Use Inter Tight 600 for every heading and label, with normal letter spacing.
- Fill large areas with violet, or add a second accent colour.
- Add drop shadows to cards; use surface steps and hairlines.
- Use ink-subtle #888888 for text under 15px or for anything that must be read first. It is only 3.5:1 on white and 3.3:1 on #F5F5F5; keep it for 15–16px descriptions and stat labels.
- Use weights above 600 or below 500, or set any label in uppercase.
- Round buttons into pills. Buttons are 9px; only the subscribe field is a pill.
- Leave placeholder Latin copy in service cards; write real two-line descriptions.
