# Trust signals absent above fold — dev spec
Site: stripe.com · Priority 7 · High · Effort: Low (0.5-2 days)

## Problem
Homepage and pricing page lead with product and pricing copy but show no visible trust signals such as customer logos, security badges, or review ratings in the primary decision area.

## Evidence (from the live site)
> The page's main headline reads “Financial infrastructure to grow your revenue. Accept payments, offer financial services, and implement custom revenue models—from your first transaction to your billionth”.
> A section heading reads “Flexible solutions for every business model”.
> 3 distinct calls to action compete on the same page: “Sign in”, “Start now”, “Contact sales”.

## Current state
h1: Financial infrastructure to grow your revenue. Accept payments, offer financial services, and implement custom revenue models—from your first transaction to your billionth.; cta: Sign in | Start now | Contact sales; notes: No trust signals near primary CTA.

## Required change
h1: Financial infrastructure to grow your revenue.; cta: Start now; notes: Add customer logos, security badges, or rating summary near headline and CTA.

## Acceptance criteria
- GIVEN a first-time visitor on the affected page
- WHEN the change is live
- THEN Add customer logos, security badges, or rating summary near headline and CTA.
- AND no layout regression at 375px / 768px / 1280px
- AND the changed control is keyboard-reachable with an accessible name

## Tracking

## Rollback
Feature-flag the change; revert if the primary metric drops for 3 consecutive days.
