The lesson
Put the customer's share of your product's work in the headline, so the proof is the title and not a paragraph below it.
The headline is "The coding agent behind 75% of Ramp's merged PRs" on a near-black page, under a Customers / Ramp breadcrumb. Below it sits a single wide photo of a man in a cable-knit sweater typing at a laptop in a warm, dim room. No logo wall or stat row appears above the fold.
Don't copy the 75% claim or the PR framing; they only fit a coding-agent story. Keep the habit of one measurable share of the customer's own work as the title.
