Institutional partnership — physician-attested SDOH data at scale

The infrastructure aging forgot.

53 million unpaid caregivers hold the US health system together — no badge, no record in the EHR, no measurement of outcomes they produce. Home care platforms churn 77–85% of caregivers annually. The gig economy is Standard Oil trying to deliver electricity one household at a time.

A century ago, a cooperative grid fixed the same infrastructure gap in a generation. Vimty is the license and the protocol layer that applies that model to aging care now. Boulder is Node One. The stack is live. The data feed is physician-attested and FHIR-ready.

Boulder — Node One opens

In 1930, fewer than one in ten American farms had electricity. Private utilities ran lines to profitable urban density and stopped. Rural communities were simply not worth the capital per mile of wire. The market verdict: you do not get power.

Franklin Roosevelt signed the Rural Electrification Act in 1936. The mechanism was not a government utility. It was government-backed cooperative loans to communities that would form their own cooperatives, build their own lines, and own the infrastructure they depended on.

By 1960, 90% of American farms had electricity. The rural electric cooperative is now 87 years old. It has outlasted every gig-economy power scheme because its incentives compound: the member-owners who need the electricity are the same people who own the grid.

The care grid — same model, same form

Generation

Caregivers produce care hours. Worker-owned cooperatives employ them W-2. The same shift that delivers care produces the clinical observation.

Transmission

CareOS + HarnessHealth attestation + chanio memory + myon.clinic FDA-cleared patient monitoring + JetBridge AI orchestration — the protocol layer. Licensed at cost to every node. The wires that carry it.

Distribution

Local cooperatives — the last mile into each home. Community-owned, locally governed. Each node owns its own equity. The grid interconnects them.

Metering

Care-hour credits — the kilowatt-hours of the care grid. Earn a care hour in Boulder. Redeem it in Amsterdam. The ledger keeps the account.

Standards

Omaha System to FHIR mapping — the voltage standard. Every observation from every node is hospital-grade, audit-defensible, interoperable.

Ownership

Member-owners hold equity in their local cooperative, not in a holding company above them. Democratic governance. The incentive structure that made the REA last.

Seven layers · what you actually buy

A coherent organization of layers to humanity.

Vimty is your read access into a network of physician-governed agents running across seven layers of every member's life. You don't pay for a dashboard. You pay for the attested observation feed produced by people actually being cared for.

Layer 1 · Arrival
Members enter the network
Risk-stratified intake from 12 condition funnels + cooperative onboarding. Cohort assembly happens here.
Layer 2 · Belonging
One identity across 41 surfaces
Apple Wallet ID + LCA member share + cooperative governance vote. Same identity for every observation in the feed — no duplicate-record problem.
Layer 3 · Daily flow
Sage runs in the background
Persistent context, cross-LLM portable. Every interaction adds to the longitudinal record without form-fatigue.
Layer 4 · Meaning
Family timeline + values clarification
Advance directives, care goals, multi-generational story. The narrative scaffolding that makes Layer 6 humane instead of transactional.
Layer 5 · Body your feed
Physician-attested SDOH observations
This is what you actually buy. Every observation hashcare-signed, ICD-coded, time-stamped, member-linked. Risk-adjustment-ready, audit-defensible. PMPM + per-care-gap + uplift share.
Layer 6 · Care production engine
Worker-owned cooperative caregivers
The same caregiver shift that delivers the care also produces the observation. The same shift pays twice — patient pays $19/mo membership, you pay PMPM for the resulting SDOH feed. Closed loop, low CAC.
Layer 7 · Mind
Compounding personal context
Member's own AI-grounded context, owned by them, signed by us. Members stay because their context compounds. Retention becomes mechanical.

Brands are doors; layers are the rooms. You buy Layer 5 output, produced by Layer 6 operations, sustained by Layers 1–4 + 7 infrastructure. Every layer is agentic. Every observation is physician-attested. Every member is sovereign-owned. The same shift pays twice.

The unmeasured layer

Aging is held together by people the system does not count.

The family caregiver is the single most important variable in whether a discharge holds, a medication is taken, a fall is prevented, a hospital readmission is avoided. None of that caregiving shows up on a claim, a chart, or a board-level dashboard.

It does show up — in strain, in absenteeism, in cost shifted to emergency departments, and in outcomes the health system takes credit or blame for without knowing the real cause. ARCHANGELS calls the caregiver the vital sign most organizations are not measuring. That framing is correct. The implication is that the industry is running blind on the variable that matters most.

When we talk about aging infrastructure, we do not mean hospitals, senior-living towers, or another app. We mean the human layer that is already doing the work. It needs a record, a structure, and a way to compound.

Why current fixes fail

The two dominant answers — the gig economy, and the chatbot — are each structurally broken.

1. The gig model cannot retain the caregiver.

U.S. home care runs on ~85% annual caregiver turnover (industry baseline reported by Sequoia’s 2026 services analysis). Matching a family to a worker who will churn inside the year is not infrastructure. It is a fee on catastrophe.

Honor (Sequoia-backed) has applied AI to scheduling preferences and brought churn down to the mid-30s. That is meaningful. It is also still gig — the caregiver is a contractor in somebody else’s platform, and the improvement is priced in to the platform, not the worker.

2. The unsupervised chatbot cannot be trusted with medicine.

A 2026 wave of peer-reviewed studies is converging on the same conclusion, in four journals in the space of months: chatbots cannot be the patient-facing clinical interface without a physician in the loop.

BMJ (2026)
Generative AI chatbots and medical misinformation — accuracy, referencing, readability audit
Five popular chatbots tested on 10 medical questions. Nearly half of responses were highly problematic. Outputs consistently expressed with confidence and certainty, filled with hallucinations and fabricated citations.
JAMA Network Open (2026)
Large Language Model Performance on Clinical Reasoning Tasks
21 frontier models across 29 clinical questions. Conclusion: current LLMs remain limited in early diagnostic reasoning and cannot yet be relied on for unsupervised patient-facing clinical decision-making.
Nature Medicine (2026)
Reliability of LLMs as medical assistants for the general public
Randomized, preregistered study. LLMs in lay-public hands identified the relevant condition in fewer than 34.5% of cases — no better than a control group. Patients could not guide the model to the right questions.
Nature Medicine (2026)
ChatGPT Health performance in a structured test of triage recommendations
Among gold-standard emergencies, the system undertriaged 52% of cases, with inconsistent activation of crisis safeguards. Safety concerns warrant prospective validation before consumer-scale deployment.
I warned three years ago that these systems were “purveyors of authoritative bullshit” that should not be trusted. That is still true — and it very much applies in medicine. — Gary Marcus, April 2026, revisiting a 2023 warning in light of four new peer-reviewed studies

The gig economy churns the worker. The unsupervised chatbot hallucinates the plan. Neither has the structural shape the aging population needs.

The shift under all of this

Services are the new software.

Julien Bek of Sequoia framed the shift cleanly in March 2026. The next wave of AI winners will sell outcomes, not tools. Pure software gets replicated by incumbents, underpriced, or built in-house. The durable companies are full-stack — they own the care model, the patient relationship, the clinical data, and the operations. AI embedded across that stack reinforces the service, instead of being the service.

A copilot sells the tool. An autopilot sells the work. — Julien Bek, Sequoia Capital, “Services: The New Software” (March 5, 2026)

In healthcare the shift is already moving. Honor, Ro, Akido, Everlywell, Aledade, Virta, Origin, Cityblock — eight services companies cataloged in Sequoia’s follow-up analysis, all with AI embedded across a care-delivery stack they own end-to-end. Each one is proof that the margin profile of a services business changes when AI takes real cost out of care delivery.

Vimty’s argument is one step past Sequoia’s: if services are the new software, then the ownership structure of the service is the moat. Capital-owned services compound for the fund. Worker-owned services compound for the worker, the family, and the community around them.

Community leverage = the moat

Make the worker an owner. Make the community the customer of last resort. Then embed the AI.

The home-care-specific proof already exists. Cooperative Home Care Associates (CHCA) in the Bronx has been running the model Vimty is arguing for since 1985 — 2,500+ caregiver worker-owners, ~20% annual turnover in an industry that runs at 50-85%, wages ~20% above regional benchmarks, and ~80% of profit distributed back to the worker-owners who generated it. Forty years. One borough. Still the largest worker cooperative in the United States.

Industry baseline

The Mondragon Corporation is the broader proof the worker-owned model scales. Founded in the Basque Country in 1956, now a federation of cooperatives across 35 countries, generating €11.05B in 2023 with 70,500 worker-owners. Independent data (Co-ops UK) show cooperatives survive at roughly 80% over five years vs. 41% for conventional small businesses. Worker ownership is not idealism. It is a survival characteristic.

What this looks like in aging care.

The gig stack
Caregiver is a contractor. Data is the platform’s. Equity is the fund’s.
  • 85% annual caregiver turnover (industry baseline)
  • Family rebuilds the relationship every year
  • Care data sits in a vendor portal and evaporates on churn
  • Upside accrues to the platform and capital stack
  • AI is added to keep contractors from leaving
The cooperative stack
Caregiver is an owner. Data is community-held. Upside is shared.
  • W-2 employment + equity in the cooperative
  • The relationship compounds — same neighbor, year after year
  • Clinical-grade record owned by the family, portable across any clinician
  • Profit reinvests into care capacity and caregiver compensation
  • AI is embedded to make the owner more valuable, not the contractor cheaper

Honor uses AI to hold the gig worker. A cooperative makes them the owner. Same retention curve, structurally more durable, and the moat is not the model — it’s the legal form.

The replication proof

Buurtzorg proved the model scales. Globally. Without a franchise.

In 2006, Jos de Blok started with four nurses in a small town in the Netherlands. No venture capital. No franchise agreement. No central operations office. One shared protocol: self-managing teams of 10–12 nurses, common technology, and a cooperative legal form that keeps every team in control of its own work.

By 2024: roughly 15,000 nurses operating in more than 1,000 self-managing teams across the Netherlands, and the model now running in more than 25 countries — including the US, UK, Japan, Sweden, and Australia — each as its own locally owned cooperative. Ernst & Young named Buurtzorg the Netherlands’ best employer six consecutive years. An independent Ernst & Young analysis found clients needed up to 40% fewer care hours than with conventional agencies, at equal or better outcomes.

The replication mechanism is not a brand extension. It is a model license. Each community builds its own cooperative on the same underlying protocol. Buurtzorg maintains the shared technology layer. The local cooperative owns the employer relationship, the patient relationships, and the equity — clean, community-held, structurally non-extractable.

Vimty’s architecture is designed for the same replication. co-op.care proves Colorado. The stack is the protocol. The next community adopts it, builds its own cooperative, and the network grows — not as a franchise, but as a federation. Each node locally owned. Each node on the same technology and attestation layer.

The licensing terms

One agreement. Three obligations. No equity extraction from the community.

Every community that federates into the Vimty grid signs a Protocol License Agreement. It is not a franchise agreement. The community owns its own cooperative, its own employer relationships, and its own equity. The PLA covers the three things that keep the network coherent: access to the shared technology stack, a care-hour solidarity contribution that funds the next node, and a one-time setup fee that covers onboarding and legal scaffolding.

Obligation 1
3%
Gross Member Revenue — solidarity contribution
Three percent of each node’s GMR flows to the network solidarity fund. The fund seeds the next community’s cooperative formation, covers legal scaffolding for new nodes, and maintains the shared technology stack. The mechanism is the same one the rural electric cooperatives used to build out lines into communities that couldn’t yet pay the full capital cost.
Obligation 2
$5K
One-time node setup fee
Covers onboarding to CareOS, cooperative legal scaffolding in your jurisdiction, the initial Omaha-to-FHIR mapping configuration, and the first three months of HarnessHealth attestation access. Includes access to myon.clinic FDA-cleared patient monitoring pathways (cardiology, orthopedics, chronic disease) and JetBridge AI orchestration for your node’s Sage AI stack. One payment. No recurring platform fee on top. The 3% GMR solidarity contribution is the ongoing network cost — no SaaS invoice.
Obligation 3
Open
Credit portability — the network promise
Every federated community agrees to honor care-hour credits earned at any other node in the network. A member who earns hours in Boulder can redeem them in your city. The care credit is as good as a kilowatt-hour was in the REA grid: a unit of the network’s collective capacity, redeemable anywhere on the wire.
What the PLA does not require
No equity transfer to Vimty Your cooperative’s equity belongs to your worker-owners. Vimty takes no stake in your community’s cooperative. The 3% GMR flows to a solidarity fund, not to a central holding company.
No per-member data licensing fee You pay the $5K setup and 3% GMR. There is no additional PMPM data fee, no per-observation charge, and no API usage billing. The solidarity fund covers shared infrastructure.
No central governance override Your cooperative is governed by your members, under your jurisdiction’s cooperative law. The PLA sets minimum protocol standards (Omaha-to-FHIR, attestation, credit portability). It does not override your governance.
No exclusivity restriction A federated node can operate additional services, community programs, or partnerships outside the Vimty protocol. The PLA covers the shared stack and credit portability. Your cooperative’s scope is yours.
The equity is always local. The protocol is always shared. The 3% GMR is the wire maintenance fee that keeps the grid connected. — Protocol License Agreement, Vimty federation terms

The build — three layers, shipping now

One operator. One attestation layer. One user-owned memory. All three live.

Vimty is not a product. It is the argument for a three-layer stack, each layer a separately shipping company, each answering a different structural failure. Together they remove the architectural harms (gig labor, unattested AI output, vendor-held records) before attempting to add capability on top.

Layer 1 — The operator
co-op.care
co-op.care
A worker-owned, physician-supervised cooperative for aging care. Caregivers are W-2 with equity. Families get one sign-up and one physician relationship. Technology runs on CareOS — 9,000+ lines of Claude-powered care-operations software, built to run our own cooperative first, licensable to operators second.
Visit co-op.care
Layer 2 — The attestation
HarnessHealth
harnesshealth.ai
Every AI output in the ecosystem passes through a physician-governed attestation layer before it reaches a patient. Hard intercept on clinical content. Authority-consumption tracking for the reviewer. The infrastructure answer to the 2026 chatbot studies: AI generates, physicians attest, patients get reviewed content.
Visit harnesshealth.ai
Layer 3 — The memory
chanio
chanio.com
The user-owned knowledge graph every AI in the stack reads from, and none of them keep. A local-first health and identity substrate — CGM, labs, wearables, clinical notes, supplements, conversations — portable across Claude, ChatGPT, Gemini, or a local model. Any AI can read it. No AI can hold it. The disk is the durable layer.
Visit chanio.com

Operator + attestation + memory. The three layers are separately fundable, separately shippable, and structurally interdependent. No one of them works without the other two.

The pre-institutional moment

Aging care today is where public health was in 1890.

Enough scientific foundation to be serious. Not enough institutional infrastructure to be systematic. A credibility spectrum that runs from rigorous research to influencer advice. No agreed scoreboard for what aging well even looks like.

Public health’s early wins came from removing harms first — clean water, vaccines, sanitation — before it tried to add capability. The architectural harms in aging today are fragmented data, gig labor, and unattested AI clinical output. Vimty’s thesis is that those harms have to be removed first. The capability layer comes next, and safely.

MIT AgeLab launched a Longevity Preparedness Index in October 2025 to try to measure what preparedness for a longer life looks like at the individual level. Joseph Coughlin’s broader argument in The Longevity Economy is that an aging society is the most misunderstood market of our era. Vimty’s contention is that individual preparedness is not enough. The unit of preparedness is the community, and the infrastructure is cooperative.

Community leverage is how removal happens. Capital alone cannot retain the caregiver, audit the chatbot, or hold the record. A cooperative can.

The real token

Earn care now. Redeem it later. Anywhere in the network.

In the early 1990s, Japan’s Nippon Volunteer Network Active Life built the Fureai Kippu — loosely, “caring relationship ticket.” The mechanism: help an elder today, earn a time credit, keep it in a mutual-aid ledger, redeem it when you or your family need care — including through affiliated organizations in another city. At its peak, 374 nonprofits operated the system across Japan, with the largest node — Nippon Active Life Club — serving 37,500 members across 137 regional centers.

This is the oldest and most tested care token in existence. Not speculative. Not blockchain-dependent. A cooperative-ledger time credit backed by actual care capacity in every affiliated organization. One hour given earns one hour redeemable.

Contribute ten hours. Get the future you want. — The Vimty network at scale: mutual aid as infrastructure

Vimty extends this model to a federated cooperative network. Every hour a co-op.care worker contributes earns a time credit in the cooperative’s member ledger. Credits are member-owned, cooperative-held, and — as the network federates — redeemable at any affiliated community. When you age, wherever you are, the hours are yours.

Colorado, 2026 — building

The settlement layer
One hour in. One hour out. Anywhere in the network.
A member who earns care credits in Boulder can redeem them in any federated community once that community is live. The value of the network compounds with every new node — mutual-aid network effects, without the speculation of a digital token.
The governance
Cooperative ledger — not blockchain
Time credits are tracked in the cooperative’s own member-ledger accounting. Member-verified, physician-supervised, LCA-governed. Auditable, portable, and legally clean under existing cooperative law in the US, EU, UK, Japan, and Australia.
Where the equity lives — and where it does not

The equity stake in this network is not central. A cooperative owned by a central entity is not a cooperative. Vimty is the protocol layer — CareOS, HarnessHealth attestation, chanio memory — licensed to each community at cost. No equity in the infrastructure layer. No central extraction.

Each community that federates forms its own locally governed cooperative entity. The founding stake — the real token — is in that entity. Its workers hold equity in their community’s cooperative, not in a holding company above them.

Notes: Netherlands Coöperatie U.A. is the proven form — Buurtzorg uses it across 25+ countries. Germany eG requires membership in a cooperative audit association (Prüfungsverband), adding formation overhead. Japan’s Worker Cooperative Corporation is new (2022) and carries minimal homecare operational track record so far; several pilots underway. Canada’s strongest cooperative ecosystem is Quebec.

Found Boulder — $10K, 0.5% LCA equity

The real token is a care hour, or a stake in your community’s cooperative. Locally held. Locally governed. Not pooled at the center.

The grid is open. Plug in.

The Rural Electrification Act built a cooperative grid now serving 42 million member-owners across 56% of US land mass. It is 87 years old and still running. Boulder is node one of the care grid. You can found it, join it, attest for it, or build the next node in your city.
