Mobile web

54Fair

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture123
  1. Header missing CTA — "Get a demo" vanishes on mobile, leaving only a hamburger and no tappable action anywhere in the capture.
  2. Truncated board columns — The "In Progress" column and its cards are cut off mid-word at the right edge — desktop kanban never re-flowed for phone.
  3. Oversized hero headline — Headline scales down too little, wrapping into six lines and pushing all product content past the fold.

CTA

62Fair

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

Antigen
RunSybil
XBOW
Terra Security

Problems

  • no CTA in hero, nav-only
  • mobile fold has no visible CTA
  • demo click feels sales-heavy
  • small footprint vs. headline

Information hierarchy

68Fair

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

Information hierarchy annotations on the desktop capture123
  1. Product UI overload — The full kanban board with sidebar, search, filters, and six vulnerability cards asks the visitor to parse a dense app screen before any CTA repeats.
  2. Nav link row — Seven nav items plus Sign in create eight exit paths before the single 'Get a demo' button.
  3. Board search bar — A functional-looking search field with ⌘K shortcut inside a static screenshot invites interaction with a non-conversion element.

Trust

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

Value props

76Fair

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

Antigen’s headline sellsAntigen is the AI adversary that maps, exploits, and secures your entire attack surface.

Working

  • "AI adversary" is a sharp, memorable category frame
  • Verb chain maps/exploits/secures is concrete
  • Hero UI proves exploits are reproduced and verified

Could improve

  • No subhead to add proof or specifics
  • Zero numbers anywhere in the fold
  • Buyer outcome (relief, speed) left implicit
