Value props

76Fair

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

Reason Machines’s headline sellsReason Agent: Your team's autonomous software engineer.

Working

  • Headline names true value in one line
  • Hero demo shows real PR with diff stats
  • "Backed by Y Combinator" adds credibility

Could improve

  • No subhead — zero specifics in the copy
  • Numbers live in screenshot, not headline
  • No emotional or outcome-based hook

Information hierarchy

78Fair

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

Information hierarchy annotations on the desktop capture1234
  1. Announcement banner arrow — The 'Introducing Reason Agent 1.0' banner is a full-width exit path sitting above the headline, competing with the fold's one action.
  2. Nav links row — Five equal-weight nav links plus a high-contrast 'Log in' button give attention six exits before the hero CTA.
  3. Product screenshot detail — The three-pane app capture is packed with micro-copy (branch stats, reviewers, checks) that reads as noise at fold scale rather than a single legible outcome.
  4. Backed by YC pill — The clickable 'Backed by Y Combinator ›' chip sits directly above the headline in the scan path, inviting an exit before the value prop lands.

Mobile web

84Strong

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture12
  1. Shrunken desktop screenshot — Three-pane desktop UI scaled to phone width renders all its text illegibly small.
  2. Try Reason CTA — Button floats at roughly half column width instead of the full-bleed tap target mobile allows.

CTA

86Strong

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

Problems

  • four words, just over ideal length
  • no payoff echo of headline promise
