Value props

15Poor

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

Working

  • YC badge lends credibility
  • Striking, memorable visual

Could improve

  • No headline or subhead at all
  • Visitor can't tell what it does
  • Visual decorates, doesn't explain

Mobile web

18Poor

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture12
  1. Backed by YC badge — The only text in the viewport is a credential badge; it names the investor, not the product or action.
  2. Ghosted background artifacts — Faint video frame remnants bleed through the top half, making the hero look broken rather than intentional.

Information hierarchy

22Poor

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

Information hierarchy annotations on the desktop capture1
  1. Backed by YC badge — The only text in the fold is a credibility badge, which outranks a value proposition that does not exist.

CTA

30Poor

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

Problems

  • no CTA anywhere above the fold
  • no nav or link besides YC badge
  • visual-only hero offers no action
