Physiology,
anywhere.
Measure how the body is changing. In 30 seconds, from nearly any smartphone.
Tracking Health has historically required a clinic or a device.
Go Somewhere
Doctor's Office, Urgent Care, or the Hospital. More accurate clinical ground truth, but infrequent, expensive, and episodic.
Wear Something
Smartwatches, smart rings, and continuous patches. Continuous context when it's worn but limited by high-level insights, device cost, and high consumer drop-off.
Just Measure
30-second smartphone scan. No dedicated wearable required. The optical sensor 6 billion people already carry becomes an ambient physiological portal.
The smartphone camera observes the same broad class of optical blood-flow signal already used across wearables and pulse oximeters. Preemptive spent years making that signal reliable across consumer hardware — and teaching models to learn much more from it.
We turn a 30-second fingertip scan into an understanding of your physiology.
30-SECOND FINGERTIP SCAN
User places a fingertip over any standard smartphone camera.
BLOOD FLOW WAVEFORM
The acquired blood flow signal extracts personalized hemodynamics, arterial reflection waves, and microvascular characteristics.
FOUNDATION MODEL
Our foundation model translates the raw optical time-series into high-dimensional embeddings trained across 12M+ paired waveforms.

PHYSIOLOGICAL UNDERSTANDING
Longitudinal baseline modeling detects meaningful personal departures from baseline across recovery, illness, medication, and autonomic trends.
User places a fingertip over any standard smartphone camera.
A high-dimensional window into the body's circulation.
When physical or autonomic demand shifts, circulation adjusts immediately. Preemptive captures these subtle adjustments directly from the smartphone camera — enabling non-invasive health tracking on demand.
Explore our deep learning architecture, multi-organ pulse wave mechanics, and benchmark validations across 12M+ clinical records.
One physiological capability. Many ways to use it.
The same underlying breakthrough — capturing continuous physiological representations from existing smartphone cameras — creates distinct value depending on who integrates it.
"Give the conversation something the user didn't have to tell it."
Preemptive detects physiological change before users articulate symptoms. AI can ask the most informative contextual question.
Every measurement makes the product more personal.
Better understanding leads to better conversations, which builds fundamentally more indispensable products. Preemptive transforms everyday apps into essential health companions through a compounding loop of personalization, engagement, and deep personal baselines.
"Know me now"
From the very first 30-second scan, a 128-dimensional embedding captures multi-organ circulatory dynamics, arterial wall compliance, and autonomic balance — anchoring the user in latent space with instant personalized context.
"Something new"
Because circulation continually adapts to sleep, stress, workouts, and medications, every 30-second on-demand scan captures fresh state changes — giving the user and AI assistant an ongoing reason to check in and observe how the body responded.
"Know me better"
Weeks and months of scans build a calibrated personal baseline ("You vs. You"). Subtle departures from normal trigger timely, contextual check-ins, creating an indispensable longitudinal moat.
Designed for frictionless integration.
Camera-Native Mobile SDK
Embed 30-second physiological capture directly into iOS and Android apps. Works across 200+ hardware camera modules with zero hardware friction or shipping costs.
Physiological Vector API
Access continuous high-dimensional embeddings directly via API to ground LLMs, risk engines, and digital therapeutics.
Longitudinal "You vs. You"
Automatic personal baseline calculation surfaces early divergence from personal normal rather than relying on noisy, un-personalized population averages.
