Why I built Cellar
Even world-class care breaks down when your health history is scattered.
By Panashe Mahachi, Founder of Cellar. Published .
I built Cellar after seeing the same problem repeat itself across some of the best healthcare institutions in the world.
Over the years, my family and I have sought care, testing, imaging, and preventive health work across institutions and clinics including Mayo Clinic, Cleveland Clinic, Atria, Prenuvo, Human Longevity, Cedars-Sinai, Médica Sur, the American Hospital of Paris, Thanyapura in Thailand, and others.
These are named only as places where my family and I have been patients. They do not endorse, sponsor, or partner with Cellar.
Many of the people we met were excellent. Many of the institutions were world-class. The problem was not that the care was low quality.
The problem was that nothing spoke to each other.
A blood test in one place. A scan somewhere else. A DEXA at another clinic. Specialist notes in one portal. Imaging in another. A PDF buried in email. A result translated in one country but not another. A doctor trying to understand the full picture in a short appointment, with only a fraction of the context available.
The more sophisticated the healthcare journey became, the more fragmented it felt.
Even with access to excellent care, the patient becomes the system integrator.
You are expected to remember what happened, find the files, explain the timeline, forward the right attachments, translate the relevant records, and help every new doctor understand what the last doctor already knew. That is too much to ask of patients and families. It is also a waste of clinical talent: doctors make better use of their judgment when they can see the full picture, the labs, the scans, the timeline, and the changes over time.
Cellar exists to solve that.
What Cellar is
Cellar is a private health-record vault for people whose health information lives across many doctors, clinics, hospitals, countries, portals, PDFs, emails, and devices. It collects your records, organizes them, helps you understand what you have, and shares a clear picture with the people helping you. When you change doctors, travel, seek a second opinion, or help a parent, your information should be ready.
Not scattered. Not trapped. Not forgotten. Ready.
Cellar organizes, restates, and charts your own records. It is not medical advice and does not diagnose.
Why Cellar is different
Most healthcare software is built for institutions. Cellar is built for the person. We do not sell your health data, advertise against your medical history, or train AI on your records, and we do not lock you into a single hospital system, country, or provider network.
Cellar's business is a paid subscription, not your data.
Why PM & Company is building this
Cellar is built by PM & Company, my family office, and operated by PM Frontier LLC. We are not trying to build a short-term data-harvesting business. We are building a product we wanted for ourselves, for our family, and for people who face the same problem. We are taking a long view. A complete health history can help a doctor understand you faster, help avoid repeated testing, make second opinions easier, and help families care for parents, spouses, and children.
What we believe
- Patients own and control their own records.
- Privacy is the foundation, not a feature.
- Your records should be useful to you without being exploited.
- The best care happens when a doctor can see the full picture.
- The future of health is global, personal, and data-rich, but only with the patient in control.
Built for patients. Useful to doctors. Controlled by you.
Longevity, prevention, a second opinion, caring for a parent, a move abroad: each one begins with Cellar.
Your medical life, carefully kept.
