The Challenge
The stakes
are real
In cardiac arrest and stroke, every minute of delayed treatment costs tissue that does not come back. Ambulance demand keeps rising and paramedic churn is high: only 28% are still on the road a decade after registration, compared to 73% of doctors.

Reducing response times is both hard and expensive.

How Weewoo fits
The Weewoo
approach
Weewoo integrates with existing Computer Aided Dispatch (CAD) systems. Dispatchers stay in command and accept, modify, or ignore every recommendation.
Weewoo is not a Large Language Model. It is a machine learning algorithm built for ambulance dispatch: it cannot hallucinate.
Weewoo changes which unit is sent. It does not affect triage and it does not affect routing.Does not affect triage or routing.

Weewoo's Operational Impact
Engineered
for the field
Independently Validated
Via an independent simulation on real data.Via an independent simulation using a full year of historic emergency data. .
Less Time On The Road
Lower running costs, less vehicle wear, and less of a paramedic's shift spent driving.
Breaks And Shift Ends Protected
Dispatchers decide whether crews get home on time.Dispatchers decide whether a crew gets a break or home on time. Weewoo improves the rate of both, reducing paramedic churn.
20-unit fleet KPI improvements
Annual fleet travel −203,000 km
Paramedic driving hours −5,000 hrs
Shifts running 2 hrs+ over −22.6%
Missed meal breaks −25.2%
Breaks taken in window +3.4%
From one year of data of a twenty-unit fleet serving ~550,000 people, measured against Weewoo's benchmark approximating the service's own dispatch procedure.
Weewoo's Patient Impact
Real change
real lives
Weewoo reaches patients sooner across every priority class. It improves the slowest responses most, which is where patient harm sits.
~80 lives

Est. stroke brain aging avoided a year, New Zealand
Response time KPI improvements
P1 (n=726) 46 sec 51 sec
P2 (n=22,356) 14 sec 51 sec
P3 (n=27,130) 3.9 min 12.6 min
P4 (n=5,805) 4.5 min 10.2 min
The 90th percentile measures a service's slowest responses and is the figure most services are formally held to.
Weewoo's Values
Built with patients
front of mind
01
Reliable
Weewoo cuts response times across every priority class, not only the most urgent.
02
Intelligent
Weewoo works within your existing standard operating procedure when it chooses a response.
03
Transparent
Every recommendation is auditable and explainable. Dispatchers stay in command, and can always override.
04
Resilient
A system that fails when it is needed most is worse than no system. Built for observability and failover.
