We didn't set out to build software.
We set out to improve the outcome of emergencies.
Since 2013, OnScene Technologies has built the tools that close the gap between an emergency and the people it affects.
EMERGENCIES DON’T FAIL ON EFFORT. THEY FAIL ON INFORMATION.
SILOED COMMUNICATION
We tell people to call 911 or 999 when they see danger or have a medical emergency. And when they do, police, fire/rescue and EMS respond.
NO PROXIMITY AWARENESS
As help arrives, people nearby, employees, visitors, and other occupants hear sirens and wonder what’s going on.
At 6:28 PM on July 25th, 2025, a lone gunman approached 345 Park Avenue in New York City.
As the shooting started in the lobby, people nearby called 911 — but nobody alerted occupants on the 43 floors above.
At 2:21 PM on February 14th, 2018, a security monitor at Marjory Stoneman Douglas High School in Parkland, Florida watched a known, armed threat get out of an Uber and start walking toward Building 12.
As the shooting started on the first floor, people on the second and third floors were unaware of the danger until they were face to face with it.
THE IDEA
WHAT IF EVERYONE NEARBY KNEW THE MOMENT THE CALL WAS MADE?
One report. Everyone who needs it. At the same time.
When an emergency is reported, the people nearby and the agencies responding get the same picture in the same moment — so the people who can act already have. That’s the idea behind everything we build.
THE PLATFORM
ONE PLATFORM. WHEREVER YOU ARE.
The same idea, built for the emergency number your people already know to dial.

WHY ONSCENE
THIRTEEN YEARS BUILDING FOR THE WORST DAY — AND EVERY DAY BEFORE IT.
We’ve worked on this one problem since 2013: making sure that when something happens, the people who need to know, know. Not eventually. Not after the sirens. In the same second.
