Proactive Health Tracking and Longitudinal Health Vault

Your health
deserves a
passport.

Launching soon

Your body has been telling the truth. You've been holding it together for years.

Precedent Lab is the longitudinal memory you've been keeping in your head. Every visit, every signal, everything you've tried. As far back as you can remember. Yours to bring.

We're building the infrastructure.

The problem

You've become the custodian of your own care.

Without infrastructure, without support, without anyone else even knowing it's the job you've been doing.

You're the one who remembers the medication you took for six months in 2021. You're the one who logs the supplements, who keeps the intake forms straight, who knows which specialist saw what. You built the spreadsheet because nobody else was looking at the pattern. You translate your own story between practitioners every time, because no one else has the full picture.

You filled out the same intake form three times this year. You paid $400 for a panel and stared at ninety-seven numbers at midnight, with no one to put them in context. You spent a year on a supplement stack and can't remember half of what you tried. You've done the work. The system doesn't know you did.

And the labs came back normal while your body was living something else. The values were in range. And there was nowhere to put what you knew. The system was designed to read the number, not the person standing next to it.

You thought:

Optimal for me should be different.
I am not the average of my population.

Your car has a maintenance record. Your phone has a backup. Your tax returns are in a folder you can find. Your medical record exists in fragments, in systems you can't reach, and no one has ever been responsible for keeping the whole. So you became the one who does.

You've been holding it together for years.
Now somewhere, finally, it's held with you.
Who it's for

Four kinds of custodians.

Built for the people who've been holding their own story together. Who knew, even when no one else did.

01. The File
Chronic concern

The Symptom Investigator

You've been carrying the file for years. Three specialists. Five lab portals. The supplements you tried in 2023 that nobody remembers. Every practitioner you see needs the whole story, and you're the only one who has it. We hold every result, every symptom, everything you've tried. From here, you're not carrying it alone.

02. The Keeper
For the people you love

The Generation Keeper

You're keeping it for someone else. A parent. A partner. The intake form you fill out for them from memory, every time. Their medications, their specialists, the fall last March, the medication change in July, the supplement the naturopath added in October. You've been doing the keeping that nobody else was. What you've been doing, finally has a place.

03. The Stack
Protocols, measured

The Protocol Optimizer

You take the labs. You run the experiments. You spend real money on what conventional care won't track. Episodic care treats your symptoms. Your body isn't a collection of symptoms. Sleep and inflammation. Gut and mood. Endocrine and how you feel. Different systems, different practitioners, one arc that nobody is holding. One arc, watched across years.

04. The Arc
Reading what you inherited

The Drift Tracker

The diabetes, the autoimmune, the early cardiovascular story your parent's generation didn't catch in time. You test more than your doctor orders. You're looking for the early signal, not the late confirmation. We hold the arc. Every baseline, every shift, every quiet change over years. A story you inherited, finally one you can read early.

What you get

Your health happens between visits. We built the memory for it.

01. The longitudinal record

The Vault

The vault you couldn't build alone. Now built. The longitudinal record of everything you've tried. Every lab, every supplement, every protocol, every wearable signal, in one record. As far back as you can remember. Permanent. Yours to keep. Yours to share with any practitioner you choose, for as long as you choose.

02. The intelligence layer

The Steward

Reads every lab the moment it arrives. Shows you what the number means in plain words. Notices what's drifting, what's steady. Prepares the questions for your next visit so you don't carry them alone. The part of Precedent Lab that turns midnight worry into the question you walk in with.

03. The connective tissue

The Thread

Every protocol held next to what was happening around it. Every supplement, every dose, every cycle, where you can see it again. Every retest next to the version of you that came before. The story across years, told back to you.

Yours, traveling

Wherever you go, the memory goes.

To your PCP.Your specialist.Your integrative doctor.The ER team that's never met you.The Vault you've been carrying is yours, in one place.Yours to share with who you choose. Never sold. Never licensed. Never used to train external AI.

Our manifesto

We believe your body has been telling the truth.

  1. 01.

    You've been holding it together for years. The labs you keep screenshots of. The intake form you've filled out twenty times. The story you re-tell at every visit because no one else has it.

  2. 02.

    That isn't your failure. It's the system's. It was built to document the visit. Never built to hold what runs between them, or carry your story from one practitioner to the next.

  3. 03.

    Proactive health tracking, coordinated across your care team, used to require a concierge whose full-time job was your health. Most couldn't afford it. The constraint was never the science. The memory was scarce.

  4. 04.

    So we built it, and decided it should belong to you. Your labs, your protocols, your patterns, going back as far as you can remember. Not as a luxury. Because it was always yours.

Proof of what you've been carrying. Finally yours.
