In a world obsessed with direct-to-consumer health apps, CareDx is quietly building a diagnostic empire around the most critical moments in medicine: organ transplantation. With $575M in funding and 816 employees, they're not playing startup games—they're redefining transplant care.

"CareDx doesn't need your SEO traffic—they own the transplant conversation at the clinical level."

The tech stack tells another story: Next.js, Tailwind, Vercel—modern but pragmatic. They're not wasting cycles on bleeding-edge tech; they're shipping fast for a regulated industry. The presence of Calendly and CookieYes suggests they're balancing compliance with conversion, a notoriously difficult tightrope in health tech.

• They're not building a platform—they're building a diagnostic monopoly around transplant care
• Their traffic quality > quantity: 15K visits from decision-makers beats 15M from casual browsers
• The 'undefined' countries in their analytics is either a tracking gap or intentional obfuscation—both tell a story
• With $76.6M revenue from 816 employees, they're at ~$94K revenue per employee—healthy for a regulated medtech play
