THE SHARED CONTEXT INFRASTRUCTURE FOR AI HEALTH
Persistent.
Connected.
Coherent.
We’re building Health Coherence around a simple belief: everyone deserves better, more connected healthcare. VIVAKEY is a patient-controlled health wallet that reconciles fragmented medical records, makes them securely accessible to AI assistants, and puts each person in control of what they share and how their information supports the care they receive.
WHERE WE FIT
The context between
health data and health AI.
Records, conversations and patient updates are spread across systems. Health Coherence is building a neutral infrastructure layer that keeps their context useful across services—with the person’s permission.
HEALTH DATA
Sources & people
Provider records, reports, personal updates and patient questions.
HEALTH COHERENCE
Persistent context
Identity, consent, provenance, translation and secure handovers.
SUPPORTED SERVICES
AI & applications
The context a person chooses to share, ready for their next conversation.
Proposed architecture. Connections and platform permissions must be validated.
A FAMILIAR INFRASTRUCTURE PATTERN
Make the connection.
Enable the ecosystem.
Plaid
Connected financial data.
Snowflake
Made enterprise data usable.
Health Coherence aims to bring those infrastructure principles to personal health information in the age of AI.
These analogies describe our ambition, not current scale, adoption or affiliation.
THE COMPANY & THE PRODUCT
Free for the person.
Built with partners.
Everyone deserves better, more connected healthcare. VIVAKEY is a patient-controlled health wallet that reconciles fragmented medical records, makes them securely accessible to AI assistants, and puts each person in control of what they share and how their information supports the care they receive.
One connected health wallet.
VIVAKEY brings together information from My Health Record, your medical practice and documents you upload. Verified identity links help ensure that each source connects to the right person.
A structured foundation for your health history.
Using healthcare standards such as FHIR, VIVAKEY organises conditions, medications, allergies, results and clinical history into a unified record that can be understood across supported systems.
A coherent record with traceable sources.
Reconciliation identifies duplicates, gaps and conflicting information while preserving original documents and their origins. Patients and clinicians can see where information came from and what still needs confirmation.
Patient-controlled access and sharing.
You decide which AI services can access your wallet, which categories of information they can read and for how long. Permissions can be reviewed, changed or revoked as your needs evolve.
Better context for your chosen AI.
Authorised assistants receive read-only access to your selected health information, helping you understand results, prepare questions and create useful summaries for consultations. AI conversations and outputs do not flow back into your VIVAKEY wallet.
Build the next layer of AI health.
We’re looking for an exceptional technical co-founder and exceptional investors to help bring this infrastructure and product to life.
