The search starts
the second you say go.
DENNIS is a community safety platform for families who love someone who wanders. An autistic child. An adult with a cognitive disability. A parent living with dementia. When they're gone, DENNIS puts verified people on the ground fast and tells them exactly how to bring your person home safely.
- ✓ Created by a parent who lives this
- ✓ Emergency alerts free, always
- ✓ Made to work in the first sixty seconds
Named for a real boy. Created by his mother.
The help is already nearby.
DENNIS coordinates the search.
Three things happen the moment you raise an alarm. DENNIS reaches the verified people closest to you. It puts them into one organized search instead of a scattered one. And it hands whoever finds your person the things that keep that first moment safe: how they communicate, what frightens them, what calms them down.
That last part is the difference between a stranger and a rescue.
Elopement Alert
For families of autistic individuals, people with cognitive or developmental disabilities, and loved ones living with dementia or Alzheimer's. One press starts an organized community search. No forms, no fumbling.
✓ Free · AlwaysMissing Person Alert
For a missing minor or a missing endangered adult when the situation isn't a wandering event. A different kind of search, with protections built for it.
✓ Free · AlwaysAssistance Alert
For the emergency that isn't a disappearance. A hard moment at home or in public brings you someone trained for your person, briefed on them before they walk in.
✓ Free · AlwaysEmergency features are free and they stay free. Nothing a family needs in a crisis will ever sit behind a paywall. We're building everyday resources alongside them, for the ordinary Tuesdays and not just the 2 a.m. ones.
Simple enough for the hardest day of your life.
Every screen assumes shaking hands and no time to read. Everything that can be set up in advance already is. When it matters, simple prompts guide you through.

A search needs people.
You're the people.
When a child goes missing, the ones close enough to change the outcome are already there. The neighbor two streets over. The shop on the corner. The crew in the church parking lot. DENNIS puts them to work, each with something specific to do.
Sign up once, help when it counts
You get verified, you set how far you're willing to travel, and then you go back to your life. When an alert comes in near you, you'll know where to be and what to look for. No experience needed. Most volunteers start with none.
Businesses and organizations have a real role
Storefronts, restaurants, faith communities, civic groups, gyms, property managers. Alert your staff. Be the place searchers gather. Check your cameras when someone asks. These are small things, and they change how these end.
Nobody asks you to be a hero
Volunteers are identity-verified and background-checked before they ever respond. You choose which alerts you take, you're never sent somewhere unsafe, and you can join the search party with others or cover ground on your own.
Families can't do this alone, they need people like you ready to step up when it's their turn to need a community.
Coordinate with the community.
Law enforcement, fire, EMS, dispatch, and search-and-rescue don't get handed a civilian app. Your agency gets its own access, built around what actually happens on these calls.
Enforcement
Paramedics
& 911
Rescue
Management
Every discipline that shows up to these calls has a place in DENNIS.
Know who you're looking for before you find them
The person's profile reaches you ahead of contact. How they communicate. What frightens them. How to approach without escalating it. The information that decides how the first thirty seconds go, in your hands before you arrive.
See where the community is searching
Neighbors are already out looking. DENNIS shows you where they are and what they've turned up. One operation, one picture, everybody pulling the same direction.
You lead. That doesn't change.
Dispatch authority stays exactly where it belongs. Your judgment and your chain of command run the call. DENNIS is a force multiplier for your agency.
Your department shapes how this works in your jurisdiction. Tell us what would actually help on scene.
It takes a community.
You are the community.
DENNIS works because people show up. We're building that network now, in every region we open, across five groups.
Families & Caregivers
Parents, guardians, siblings, spouses, and paid caregivers of autistic individuals, people with cognitive or developmental disabilities, and loved ones with dementia or Alzheimer's. This was built for you.
Community Volunteers, Businesses & Organizations
Neighbors, storefronts, faith communities, and civic groups. See what the role looks like ›
First Responders
Law enforcement, fire, EMS, dispatch, and search-and-rescue. See your agency's access ›
ASD Professionals & Organizations
BCBAs, RBTs, behavioral health clinicians, therapists, educators, advocacy groups, and nonprofits. Your expertise is what makes a safe response possible.
Providers & Care Facilities
ABA centers, clinics, schools and school districts, group homes, memory care and senior living, day programs, and state or county programs. When someone in your care leaves the property, you need more than a phone tree. So do the families who trust you.
