Superhuman is hiring a growth design manager because the web is where "tens of millions of people first encounter Superhuman". Yet real Chrome visitors to the homepage fail Core Web Vitals: the main content takes 4.2 s and taps take 312 ms to respond, and site-wide load time is 45% slower than a year ago. The homepage ships 1.07 MB of HTML, 9.3 MB in total, and has no H1, so search engines and AI assistants get no clear statement of what the page is about. For a brand built on speed, the first impression is slow.

Why it works
Set a performance budget for the homepage (HTML under 300 KB, total under 3 MB, LCP under 2.5 s, INP under 200 ms for real users). Render the hero text first, move the logo wall and lower carousels below the fold to lazy loading, give static assets long cache lifetimes, and load marketing tags after the page is interactive. Add one H1 that names the suite and its products. Track field data weekly and A/B the faster page against today's.
Faster first pages lift sign-ups on the same traffic, Google uses Core Web Vitals in ranking, and a clear H1 helps the new SEO and AEO work. It also proves the speed promise before a visitor tries the product.

Keep the faster page visually identical for the first test.
Evidence
- PageSpeed testGoogle PageSpeed for the superhuman.com homepage (October 22, 2026). Real Chrome visitors fail Core Web Vitals: the main content appears in 4.2 s and taps respond in 312 ms (good is 2.5 s and 200 ms); across the site, load time at the 75th percentile is 3.3 s, 45% slower than a year earlier. The mobile lab test scores 60/100: the largest element is the text "Trusted by the most innovative organizations in the world" at 6.2 s, 9.3 MB downloaded in 197 requests, 31 third-party services, Google Tag Manager blocking for about 0.5 s, short cache lifetimes costing about 2.7 s, and 9 browser errors.Source
