This is a thought experiment. I want to walk you through an idea, a hypothetical product I've been turning over in my head, and by the end, I think you'll find yourself asking the same question I keep asking: why doesn't this already exist?
Every time you visit a doctor, fill a prescription, or sync a fitness tracker, you generate data. Rich, detailed, commercially valuable data about your body, your habits, your conditions. And almost none of it belongs to you.
Right now, hospitals, insurers, pharmacies, and data brokers are quietly packaging that information and selling it to pharmaceutical companies, to researchers, to advertisers. The global market for health data is worth tens of billions of dollars. You are the product. And you receive nothing.
So here's the concept I've been exploring. I'm calling it MedVault.
The Hypothetical Product
Imagine a health data platform that puts patients in control. You connect your medical records, your wearable devices, your test results, and the platform creates a secure, encrypted vault that only you hold the key to. From there, you decide who gets access to your data, under what terms, and for how long.
And crucially, when a researcher, pharmaceutical company, or health institution wants to use your data, they pay you directly. Not a hospital. Not a middleman. You.
"The global market for health data is worth tens of billions of dollars. You are the product. And right now, you receive nothing."
The platform would be built on HIPAA-compliant infrastructure with full consent management baked in. Every access request is logged. You can revoke access at any time. The default is always privacy, and nothing leaves your vault without your explicit permission.
The tagline, in my head, has always been the same: the health app that pays you.
What It Would Actually Look Like in Practice
Picture a woman living with Type 2 diabetes. She's been managing her condition for eleven years. She checks her blood sugar four times a day, has been through three medications, two dietary overhauls, and one clinical trial. Her health journey is a dataset that pharmaceutical researchers would pay significantly for — the kind of long-term, real-world evidence that is genuinely hard to come by.
Under the current system, her hospital sells that data, anonymized in name though often identifiable in practice, and she sees none of the proceeds. Under MedVault, she licenses it on her own terms. She earns $20 one month, $60 the next. It's not life-changing money in every case. But it is her money, from her data, given with her consent.
Scale that across millions of patients — chronic conditions, genomic data, mental health histories, rare disease profiles — and you begin to see not just a product, but a new economic model for healthcare data entirely.
Why the Idea Matters Beyond the Money
Ownership changes behavior. When patients understand their data has real value and they control who sees it, the relationship between patients and the healthcare system shifts. People become participants, not just subjects. That shift has implications far beyond the financial.
Patients who feel ownership over their health data are more likely to track it carefully, share it with their care teams proactively, and engage with research that might actually help people like them. The data gets better because the people generating it are invested in it.
The Market Already Knows This Is Coming
Every major tech company is positioning for this space. Apple Health Records. Google Health. Amazon Clinic. They're all building infrastructure to hold health data at scale. The question isn't whether health data will be centralized — it will be. The question is who controls it.
MedVault is a bet that the answer should be the patient. Not as a regulatory requirement. As a product decision. Because if you give patients genuine control, the quality, depth, and consent clarity of the data you collect is categorically better than anything scraped or purchased.
Why It Doesn't Exist Yet
The honest answer is that it's hard. Health data infrastructure is complicated, regulated, and fragmented. Getting hospitals, insurers, and wearables to talk to each other in a way that's actually useful is a significant technical challenge.
But the harder problem is trust. People need to believe that their data is actually secure, that the consent mechanisms actually work, and that the company behind it won't pivot to selling the data wholesale the moment VC pressure increases. Trust in this space has to be earned slowly and lost instantly.
That's the real moat. Not the technology. The trust.
This is a thought experiment and concept exploration, not a live product. If this idea resonates with you or you're building in this space, I'd genuinely love to talk.
