Share911 and Share999 let schools, workplaces, and venues share critical information, issue alerts, pin the exact location of danger, report missing and found people, and keep everyone updated as an incident unfolds — on the phones and computers your people already carry. On ordinary days, the same tool handles outages, closures, and operational issues.
WHAT IT DOES
Everything an incident needs you to say — from the device in your hand.
Five things anyone on site can do in seconds, from a phone or a computer — and everyone who needs to know, including the agencies responding, gets it at the same moment.
Share critical information
What’s happening, reported by the person who sees it, delivered to everyone at once.
Issue alerts
Lockdown, evacuate, shelter, all clear. One button — by push, text, desktop, email, WhatsApp, and your audible and visual systems.
Pin the location of danger
Floor, room, door. People move away from it. Help moves toward it.
Report missing and found people
Who’s accounted for, who isn’t, and where the found ones are — live, for reunification.
Send incident updates
Keep everyone informed as it develops. Nobody is left in the dark after the first alert.
NOT JUST THE WORST DAY
The tool your people use every week is the one they’ll know how to use when it matters.
Most days nothing terrible happens — but something always does. Share911 and Share999 carry the everyday traffic too, so when an emergency comes, the alert goes out from a tool your people already have open.
Utility outages
Power, water, HVAC, network down. Tell the building, tell facilities, tell the people who need to leave early.
Business continuity
Closures, delayed openings, weather days, system failures. One message, every channel, everyone on the roster.
Operational issues
A blocked entrance, a spill, a broken elevator, a visitor who needs escorting. Reported where it is, handled by whoever’s nearest.
Around the perimeter
Suspicious activity, a vehicle where it shouldn’t be, a police action next door. Everyone inside knows before it becomes a question.
NO HARDWARE
Runs on the devices you already have. That’s most of the cost gone.
Wearable panic buttons and badge systems mean hardware to buy, install, maintain, and replace — and a price to match. Share911 and Share999 run on the phones, tablets, and computers your people already carry: nothing to buy, nothing to install, no wires to pull, no new network to stand up. Live in days instead of months, at a fraction of what the hardware vendors charge.

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.
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.
HOW IT WORKS
One report. Three things happen at once.
STEP 1
Someone reports
Anyone on site taps one button — or scans a code — to report what is happening and exactly where.
STEP 2
Everyone knows at once
Everyone on site and the agencies responding see the same report in the same second — no phone tree, no relay.
STEP 3
Help goes straight there
The nearest trained help, incident command, and arriving responders wayfind to the exact location — one live picture until it is over.
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.
