Declaration
For everyone who has ever had to explain themselves
to a stranger holding a stethoscope.
Your body remembers the fever at seven.
The broken arm at eleven.
The first medication that made things worse before it made things better.
The diagnosis that took four doctors and three years to name.
The allergy they discovered the hard way.
The grief that showed up in your cortisol levels before you even admitted it to yourself.
Your body has kept every single record.
The system you trust with your life has scattered them across nineteen different offices, three cities, two countries, and a filing cabinet no one has opened since 2011.
A new doctor opens a file with gaps they can't see.
Not because they don't care.
Not because the technology doesn't exist.
But because no one ever built the thread.
You sit down. You have twelve minutes.
They ask you to summarise a lifetime of health in the time it takes to drink a coffee.
You forget the medication that worked in 2009.
You forget the name of the specialist in the other city.
You forget — because you are human, because you are tired, because you are frightened — and the distance between what you know and what they know becomes the space where mistakes live.
The data exists. Somewhere. Fragmented.
What doesn't exist is the narrative.
A file full of unconnected episodes is not a medical history.
It is the debris field of one.
Health apps are built to optimize today.
They measure the steps you take, not the journey you've survived.
We are building something that has never existed:
A single, unbroken, lifelong record of one human being — from the first breath to the last.
Not a portal. Not a PDF. Not a folder on your desktop that gets lost in a hard drive migration.
A thread. Continuous. Permanent. Yours.
The kind of record that means a doctor who has never met you — who is meeting you unconscious in an emergency room at 3am — already knows about the anticoagulant, the allergy, the cardiac event at fourteen.
The kind of record that means you never have to perform your own medical history ever again.
Your blood type. Your genetic inheritance. Your family history of conditions that hadn't yet surfaced. The risks already written into you before you drew your first breath.
None of it was recorded in a place that followed you home.
The hospital kept a copy.
Your parents kept a copy — maybe — in a drawer — maybe.
The next doctor started fresh.
Amara was born in Amsterdam. Within days, her newborn screening returned a sickle cell flag — two copies of the gene, one from each parent. Instead of living in a siloed hospital archive, that flag was threaded into a record that will follow her for life — waiting for every doctor she will ever meet, visible before the first consultation begins, impossible to lose between one health system and the next.
That is what SinceWhen looks like at the beginning.
That is what it should look like for every human being born anywhere in the world.
"Do you have any records from your previous doctor?"
We believe the second most dangerous are:
"I'll have to take your word for it."
We believe that a 46-second verbal catch-up is not a medical history.
That a patient who cannot speak for themselves should not be a mystery.
That a child passed between specialists should not arrive at each one as a stranger.
That a person managing a chronic condition should not have to be the only keeper of their own story.
That mental health history deserves the same permanence, the same rigour, the same dignity as a blood test result.
We believe that your thread is a clinical asset — and right now, the world is letting it evaporate.
The average person will interact with over 19 different healthcare providers in their lifetime.
That is 19 separate first chapters.
19 times you repeat your story.
19 opportunities for a critical detail to be lost in the gap between one system and the next.
A systematic review published in the Journal of Medical Systems found that complete medical histories improve diagnostic accuracy by 37%. Research published in JAMIA found that patients with truly continuous records encounter 24% fewer hospital readmissions.
But forget the percentages for a moment.
Consider only this:
A doctor who knows the whole story makes different decisions than one who only has the most recent chapter. That difference can be fatal.
No technology gap prevents us from fixing this.
Only a failure of will — and of infrastructure — has allowed it to persist.
It listens.
To your documents, your discharge summaries, your prescription photographs, your voice notes dictated in a car park after a difficult appointment.
It reads everything.
It organises everything.
It flags what matters. It tracks what shifts. It remembers what you forget.
It grows more useful the longer you live — because a thread that spans decades finds patterns that a thread that spans months cannot see.
And then, when a doctor needs to know — in an emergency, in a first consultation, in a specialist referral — it gives them a brief. Structured. Searchable. Complete.
Not a data dump.
A clinical narrative.
The full story. In the time it takes to scan a code.
You are unconscious.
You cannot say your name. You cannot list your medications. You cannot warn the surgeon about the allergy on your chart — the chart that lives in a different hospital, in a different city, behind a login no one in this room has.
Someone in scrubs is making decisions about your body with a fragment of the picture.
They are doing their best.
Their best is not enough — not because of them, but because of the gap.
SinceWhen closes the gap.
When you cannot speak, SinceWhen speaks instead.
Your record belongs to you.
Not to us.
Not to insurers.
Not to pharmaceutical companies.
Not to anyone who might find your diagnoses commercially interesting.
The thread is yours — sealed in end-to-end encryption that no one, including us, can cut open.
You decide who sees what and for how long.
The emergency QR shows only what saves your life.
The specialist link expires when you say it expires.
The full export goes to the GP you choose.
We are not building a platform where your data is the product.
We are building a sealed thread. The seal is unconditional.
No defaults. No surprises. No small print that reverses this.
No SinceWhen employee can read your records. Ever.
We built this because we asked a question no one had fully answered:
Is there a single service in the world that follows a human being — one specific, irreplaceable human being — across every healthcare interaction, from birth to death, across every country, every system, every language?
The answer was no.
That answer was not acceptable.
We decided it should stop being the answer at all.
Not much.
Start your thread.
Or start one for someone you love — a child, a parent, a person whose history is already getting harder to piece together.
Give it the first entry.
Watch it begin to build.
Because the thread has to start somewhere.
And the earlier it starts, the more it matters.
The first generation that never starts from zero again — it begins with the people who decide that zero is no longer acceptable.
The best moment to start a medical record is at birth.
The second best moment is today.
Every day that passes without a thread is another day that fragments.
Another appointment where the gaps widen.
Another specialist who fills in the gaps with guesswork.
You have already lost years of context.
You do not have to lose any more.
We will not sell your data.
We will not share your data.
We will not profit from your diagnoses.
We will build a product so good, so trusted, so indispensable —
that you pay for it directly.
The way you pay for things that matter.
The way you pay for things that are yours.
