CTA
15PoorCopy, size, verb, cost-feel — does the primary CTA earn the click?
Problems
- no CTA anywhere on the fold
- no link, button, or input exists
- YC badge intent has no outlet
Value props
15PoorTitle, subtitle, hero — do they sell the product's true value?
Sublingual’s headline vague
Sublingual
Y Combinator W25
Working
- Clean, memorable brand name
- YC W25 lends credibility
Could improve
- No statement of what product does
- No outcome, audience, or numbers
- No hero image or demo
Mobile web
22PoorThe phone experience as a first-class citizen.
1- Sublingual headline — The wordmark carries no value statement; 'Y Combinator W25' is a credential, not a reason to act.
Information hierarchy
32PoorDoes the design help or inhibit what the page is trying to say?
123- Y Combinator subtitle — The only supporting line is a credential, not a value proposition — visitors learn nothing about the product.
- Sublingual wordmark — The hero centerpiece has no CTA beneath it, leaving the scan path with no action to land on.
- Copyright footer line — The footer sits inside the first viewport, telling visitors the page is finished before it communicates anything.
Trust
32PoorProof that the product is real, competent, and safe to try.
