EMERGENCIES DON’T FAIL ON EFFORT. THEY FAIL ON INFORMATION.
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.
As help arrives, people nearby — employees, visitors, and other occupants — hear sirens and wonder what’s going on.
July 28th, 2025 — 345 Park Avenue, New York City.
6:28 PM
A lone gunman approaches 345 Park Avenue and opens fire in the lobby.
MOMENTS LATER
People nearby call 911. Dispatch and responding officers get the report.
THE 43 FLOORS ABOVE
Nobody alerts the occupants upstairs. The people closest to the danger are the last to know.
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.
February 14th, 2018 — Marjory Stoneman Douglas High School, Parkland, Florida.
2:21 PM
A security monitor watches a known, armed threat get out of an Uber and start walking toward Building 12.
MOMENTS LATER
Shooting starts on the first floor of Building 12.
THE FLOORS ABOVE
People on the second and third floors are unaware of the danger — until they are face to face with it.
THE IDEA
WHAT IF EVERYONE NEARBY KNEW THE MOMENT THE CALL WAS MADE?
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.
MEDICAL EMERGENCIES
MOST EMERGENCIES AREN’T ATTACKS. THEY’RE MEDICAL.
The emergency Share911 and Share999 is used for most often isn’t the worst day imaginable — it’s the cardiac arrest in a cafeteria, the collapse in a stairwell, the bad reaction in a hallway. In those minutes, the closest help isn’t an ambulance miles away — it’s the people already in the building.
The closest help is already there
One report shares the exact location with everyone nearby and with public safety at once — so the colleague trained in CPR, or the AED two doors down, can get there in seconds, not minutes.
Minutes decide the outcome
With something like cardiac arrest, the chance of survival falls with every minute that passes. Getting the nearest hands and the nearest AED to the right spot, fast, is where the difference is made.
In a crisis, reach the victims
EVACUATIONS
THE ALARM SAYS LEAVE. IT DOESN’T SAY WHICH WAY IS SAFE.
After medical, the most frequent reason people reach for Share911 and Share999 is an evacuation — a fire or smoke condition, an alarm or sensor going off, or severe weather threatening the building. An alarm only does one thing well: it tells everyone to leave. It can’t say where the danger is, which way is actually safe, or who couldn’t get out.
The safe way out, not the rehearsed one
An alarm says go — it doesn’t say which way. When people can see where the smoke, fire or damage is, they move away from it, instead of toward the exit they drilled that’s now blocked.
Reach the people who can’t get out
Some are trapped or hurt and can’t leave on their own. The instant they signal for help, the people nearest them — and responders — know exactly where, and can get to them right away.
One picture for command
Incident command and management see where the danger is, where help is needed, and who’s already safe — in one place, as it unfolds — instead of piecing it together from a clipboard outside.
