Value props

54Fair

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

Illume Labs’s headline vagueEverything your body is telling you, in one place.

Working

  • Taps real pain of scattered health data
  • "One place" implies consolidation outcome
  • YC badge adds credibility

Could improve

  • No subhead to add specifics
  • Hero image shows scenery, not product
  • No data sources or outcomes named

CTA

68Fair

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

Illume Labs
Guava Health

Problems

  • two equal-weight CTAs compete
  • 'waitlist' = delayed payoff
  • contradicts 'try the app' offer
  • no payoff language in label

Information hierarchy

72Fair

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

Information hierarchy annotations on the desktop capture1234
  1. Twin equal-weight CTAs — "JOIN WAITLIST" and "TRY THE APP" share identical styling, so no single primary action wins the one-second scan.
  2. Contact/schedule link line — Two underlined exit links sit directly beneath the CTAs, in the scan path where the conversion decision happens.
  3. Y Combinator badge link — An outbound link with an arrow sits directly above the headline, inviting a click away before the value prop lands.
  4. Low-contrast headline text — Thin cream serif over a busy grey sky loses legibility around "telling Illume Labs" where the background lightens.

Mobile web

84Strong

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture123
  1. Dual equal CTAs — "JOIN WAITLIST" and "TRY THE APP" carry identical weight, splitting the tap decision with no clear primary.
  2. Headline over train — Light serif text sits on the bright train car with little scrim, hurting legibility of the core value line.
  3. CTA button width — Buttons float at partial width instead of the thumb-friendly near-full-bleed expected on a phone.
