The Health Stack: Building Seven Products Across One Lifecycle

The Problem: Disconnected Health Technology

Healthcare technology portfolios are typically assembled by acquisition or convenience. A clinical documentation tool from one vendor. A compliance module from another. A telehealth add-on. A patient engagement app. They coexist in the same slide deck, but they do not connect. No data flows between them. No lifecycle links them. Each product solves its own problem in isolation.

The result is predictable: the institution deploys AI without testing the workflow, the prosthetist designs without seeing the wearer's full day, the wearer documents without the vocabulary to communicate, and the person facing cancer and limb loss navigates two timelines that nobody has connected.

The Design Principle: Each Product Feeds the Next

The health stack was not built as seven independent products that happen to serve healthcare. It was built as seven phases of one lifecycle, where each product generates information the next one consumes:

1. Healthcare Playbook defines what to deploy and in what sequence. Its readiness assessment and four-quarter roadmap become the input for VITAL.

2. VITAL tests whether the workflow survives contact with clinical reality. Eighteen workflows across six domains, fifty-four synthetic scenarios. The output is a deployment specification — not a score — that tells MedConsult AI what the workflow needs to prove in production.

3. MedConsult AI runs the clinical workflow in production. HIPAA-focused documentation, AI-assisted consultations, voice dictation, patient communication. The production reality informs what SOMA should research next.

4. SOMA centres prosthetic care research on lived experience. Three guided care journeys track pressure, volume, and discomfort across a full day. Seven research frontiers explore sensory return, adaptive sockets, muscle interfaces, shared control, regional materials, and digital-twin modelling. The research insights define what STRIDE’s wearers should be tracking.

5. STRIDE gives the wearer a structured way to document what happens between appointments. Four daily actions: describe the prosthesis, check in when the fit changes, keep photos and clinical advice, compare the same activity between morning and evening. The daily records define what Prosthetic Atlas should teach.

6. Prosthetic Atlas builds the shared vocabulary that makes both sides of the prosthetic care conversation productive. Three content pathways: Motion (gait comparison), Fit (daily comfort dynamics), The Visit (Brief Builder for appointment preparation). The vocabulary defines how STILL’s users articulate their needs.

7. STILL handles the life timeline that the clinical team is not assigned to. Four journey pathways for individuals navigating cancer treatment with limb-loss implications: facing what’s next, finding footing, living on my terms, here for someone. Trusted resource links to Memorial Sloan Kettering, Amputee Coalition, and National Cancer Institute. Real patient narratives. Support connection directory.

Three Verticals, One Architecture

The seven products serve three distinct verticals within the health stack:

Clinical AI (products 1–3): Healthcare Playbook, VITAL, MedConsult AI. Strategy, sandbox, execution. The institutional layer.

Prosthetic care (products 4–6): SOMA, STRIDE, Prosthetic Atlas. Research, records, education. The designer-wearer-vocabulary triad.

Cancer navigation (product 7): STILL. The life timeline. The human layer that makes every other product meaningful.

What the Stack Teaches About Product Design

The health stack reinforced a principle that applies beyond healthcare: the most defensible portfolio is not the one with the most products. It is the one where removing any product creates a gap that no other product can fill.

Remove the Playbook and the institution deploys without strategy. Remove VITAL and the workflow is tested in production by patients. Remove MedConsult AI and there is no clinical execution. Remove SOMA and the designer works from static fittings. Remove STRIDE and the wearer arrives with memory instead of evidence. Remove Prosthetic Atlas and both sides lack vocabulary. Remove STILL and the person facing the hardest decision navigates alone.

Seven products. One lifecycle. Each one exists because the lifecycle demanded it.
