BostonGene's mobile fold inverts the desktop hierarchy: the AstraZeneca testimonial carousel loads first, so a phone visitor sees a nine-line partner quote before any statement of what BostonGene does, and the headline "Biologically grounded AI for drug development and precision clinical decision-making" only begins near the bottom edge, wrapping into six-plus oversized lines. The primary CTA — "Explore our AI platform" on desktop — is not visible or tappable anywhere in the first mobile viewport, which is the single biggest cost here; there is no action for the thumb to take. The nav collapses cleanly into a hamburger with just the logo and search, but the floating reCAPTCHA badge overlaps the headline text. The biggest lever is reordering the mobile hero to lead with the headline and a full-width "Explore our AI platform" button above the carousel.
