CTA

63Fair

Copy, size, verb, cost-feel — does the primary CTA earn the click?

Synthace

Problems

  • no visual dominance over secondary
  • generic label, no payoff named
  • no header echo or specificity

Value props

72Fair

Title, subtitle, hero — do they sell the product's true value?

b12 Labs’s headline undersellsAI-Powered Chemical SynthesisAI that designs, optimizes, and runs chemical reactions. Accelerating pharma R&D from years to months.

Working

  • 'Years to months' is a vivid outcome
  • Subhead names what the AI actually does
  • YC badge adds credibility

Could improve

  • H1 is a generic category label
  • Hero image is blurry decoration
  • No hard numbers or customer proof

Information hierarchy

76Fair

Does the design help or inhibit what the page is trying to say?

Information hierarchy annotations on the desktop capture1234
  1. Get Started button — Outlined, low-contrast styling matches Request a Demo, so no primary action wins the scan.
  2. Blurred hero illustration — Lab-glassware render is out of focus and illegible, adding noise instead of communicating the product.
  3. Five-link nav row — Planning through Team offers five equal-weight exits before the conversion action.
  4. Nav Get Started duplicate — Second same-styled Get Started splits attention with the hero CTA instead of reinforcing it.

Mobile web

76Fair

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture123
  1. Side-by-side hero CTAs — Two half-width buttons split the tap target; the primary 'Get Started' should be full-bleed and stacked.
  2. Duplicate header CTA — A second 'Get Started' in the nav competes with the hero button for the same tap.
  3. Faint animation caption — 'What if discovery was smarter.' renders in low-contrast gray, reading like a broken or half-loaded element.
