Stripe's homepage does an excellent job establishing category authority: dense enterprise logos, quantified reliability stats, named customer stories, and a genuinely differentiated AI/agentic-commerce narrative. But the conversion architecture is diffuse — dozens of competing CTA labels, no on-page lead capture, and a gated-sounding primary action instead of a direct 'start now.' Mobile compounds this with widespread sub-32px tap targets and sub-12px text across a 20,000px scroll. The page is built to educate and reassure, not to convert the specific visitor standing in front of it.
