CTA

30Poor

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

Serna Bio

Problems

  • no CTA anywhere on the fold
  • nav links only path forward
  • headline promise has no next step

Value props

48Poor

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

Exonic’s headline vagueImagine if medicine could sense and adapt to disease

Working

  • Evocative, emotionally resonant vision line
  • Blue highlight on "sense and adapt" focuses the claim
  • YC badge lends early credibility

Could improve

  • No subhead saying what Exonic actually builds
  • "Imagine if" is hypothetical, not a claim
  • Hero visual decorates, doesn't demonstrate

Trust

48Poor

Proof that the product is real, competent, and safe to try.

Mobile web

48Poor

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture123
  1. Headline over particles — Hero copy sits on the dense particle field with no visible CTA anywhere in the fold — the blue 'sense and adapt' span blends into the busy texture.
  2. Uncollapsed nav row — Desktop 'MEDIA TEAM' links carried into the phone header instead of a hamburger, with wide letter-spacing eating the header width.
  3. Pause motion control — A utility control gets the bottom-corner slot a conversion CTA should own; it competes with the YC badge as the only footer actions.

Information hierarchy

58Fair

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

Information hierarchy annotations on the desktop capture12
  1. MEDIA TEAM nav — The only prominent buttons on the page lead away from any conversion, making exits the default action.
  2. Headline over particles — The dot field runs behind 'sense and adapt', softening legibility of the accented key phrase.
