For Helen
Mā te mōhio, ka ora
“Through knowledge, we live.”
A Māori proverb that guides everything we build.
Origin Story
The Brother and The Nurse
The Engineer
Years spent in military combat systems taught me one thing: the ocean hides danger beneath calm surfaces. Submarines operate in silence. Threats emerge from noise. The algorithms we built weren't just about detection—they were about buying time. Time to respond. Time to save lives.
I never imagined those same principles would apply to medicine. Until Helen.
The Nurse
Helen is my sister. She spent her career caring for others—decades of nursing, followed by years ensuring healthcare policy reached those who needed it most.
Over countless conversations, she shared her frustrations: the relentless alarm fatigue that numbs clinicians to real danger. The reactive nature of care—always responding to crashes, never preventing them. How sepsis hides in plain sight until it's almost too late.
Current monitoring, she told me, lets nurses down. It watches numbers but misses the patient.
Listening to Helen, I realized what had been invisible: the monitors were watching, not hunting. They reported what they saw, but they couldn't see what mattered. The subtle signs of compensation. The quiet exhaustion of a body fighting to maintain the appearance of stability.
The same signals a submarine commander looks for in sonar noise.
Aranga
In te reo Māori, “aranga” means to rise, to emerge, to come into being. It represents the journey from darkness into light—the path of recovery. We named our system after this concept because that's what it does: it reveals what was hidden, giving clinicians the knowledge to guide patients upward.
What We Believe
Our Values
See What Others Miss
We believe the most important threats are the ones that hide in plain sight. Our mission is to make the invisible visible.
Buy Time, Save Lives
Every hour of warning is an hour for intervention. We measure our success in lead time, not just accuracy.
Trust Through Transparency
Clinicians deserve to understand why an alert fires. Our system shows its reasoning, building trust through clarity.
Serve Those Who Serve
Healthcare workers carry an immense burden. We build tools that support their expertise, not replace it.
The Equity Mission
Geography Should Not Determine Survival
Rural & Isolated Communities
From remote Pacific islands to mountain villages, from Arctic outposts to inland rural communities—millions of people live hours away from advanced medical care. When a patient begins to deteriorate, distance becomes destiny.
We believe advanced surveillance technology shouldn't be a luxury reserved for tertiary care centers. The same algorithms that protect patients in major teaching hospitals should protect families in the most remote clinics.
Aranga is designed for deployment anywhere: from ICUs with full telemetry to remote clinics with basic vital sign monitors. The physics doesn't change. The algorithms adapt. The mission remains the same.
Beyond One-Size-Fits-All
Standard clinical algorithms are trained predominantly on Western populations. This creates systematic blind spots for Indigenous peoples, ethnic minorities, and communities with different physiological baselines—from vascular stiffness patterns to disease prevalence.
A “one-size-fits-all” health system fails patients whose bodies don't match the assumed norm. Rheumatic heart disease, sickle cell trait, higher rates of diabetes—these aren't edge cases. They're the reality for billions of people globally.
Aranga's physics-based approach adapts to each patient's actual hemodynamic profile rather than assuming population averages. Cultural protocols can be loaded through our External Constraint Interface—from bloodless medicine requirements to community-specific care boundaries.
“Early warning isn't just about better outcomes. In remote communities, it's the difference between a transfer arriving in time or not at all.”
