Who they are
Dr. Joel Wussow runs Healthspan by Design, a longevity medicine practice with a methodical approach to assessment and intervention. The practice needed a way to take prospective patients through a structured intake online — one that felt like a real clinical conversation, not a webform.
What we built
A custom Claude-powered progressive web app:
- Claude-powered assessment engine: A conversational intake that walks a prospective patient through a clinical-style questionnaire. Adaptive follow-up questions. Tone and language tuned for a healthcare audience.
- HIPAA-aware scrubber layer: A pre-processing layer that catches and routes any free-text PHI before it touches the LLM. The privacy posture is architectural, not policy.
- Custom system prompt: Thirteen-plus iterations to get the voice, the depth of inquiry, and the appropriate clinical caution right. We didn’t ship a generic intake bot in a wrapper.
- PWA delivery: Installable, offline-tolerant where appropriate, fast on a phone. The patient experience matches the brand without compromising on the back-end.
- Landing page: The companion marketing page introduces the assessment, sets expectations, and routes the patient into the experience.
How the engagement ran
Iterative product work. Weekly check-ins between the Kynetik build team and Dr. Wussow. Each iteration changed something concrete in the system prompt, the scrubber rules, or the UX. Thirteen-plus passes before we agreed the voice was right.
Why this matters
Most “AI assessment” pages are wrappers. This one is a product. The clinical voice was tuned by a clinician working iteratively with our build team. The privacy layer was designed by engineers who took the constraint seriously. The PWA delivery makes it feel like an application a practice actually owns, not a feature on someone else’s platform.
