CTA

62Fair

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

Stoa
Vast.aiin-product action
Shadeform

Problems

  • generic label, no value promise
  • click feels like signup work
  • doesn't echo headline's market hook
  • muted color, low visual pop in hero

Value props

72Fair

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

Stoa’s headline undersellsThe market behind AI hardwareBuy and sell GPUs with verified counterparties and price discovery.

Working

  • Hero chart shows real GPU prices
  • Subhead names buyers, sellers, trust
  • YC badge adds instant credibility

Could improve

  • Headline is category, not outcome
  • Subhead buried in right rail
  • No emotion: no pain of opaque pricing

Information hierarchy

78Fair

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

Information hierarchy annotations on the desktop capture1234
  1. Hero Sign up button — Small, low-contrast grey primary sits at nearly the same weight as "Contact our team" beside it, so no single action wins the scan.
  2. Six-link nav row — Products, Data, Research, About, Contact plus Log in give attention nine exits before the hero CTA.
  3. Learn more banner — Pill-styled announcement CTA at the very top competes with Sign up as the first clickable element.
  4. Chart price labels — Tiny monospace labels like "H100 SXM5 · $25,860" are near-illegible at this scale, muting the chart's proof value.

Mobile web

86Strong

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture12
  1. Promo announcement bar — Second header stacked above the nav; its 'Learn more' CTA competes with Sign up and pushes the hero down.
  2. Chart price labels — Monospace labels like 'GB200 NVL · $67,400' shrink to near-illegible size on the phone viewport.
