If you see a missing person right now, or someone is in danger, call 911 first.
Help bring missing loved ones home
When someone goes missing, volunteers end up searching the same ground twice, and tips get scattered across texts, calls and social posts. TipTriangle gives each search one page: a shared map of where people have already looked, and a private tip line straight to the family.

How it works
- The family gets one page to share. It has a photo, a description, the vehicle if there is one, and a way to call or text the family.
- Volunteers mark where they searched. They can track a walk by GPS, draw an area, or mark a spot. Everyone sees the same map, so the next team covers new ground. Searched areas fade as they get older, because one pass can miss things.
- Anyone can send a private tip. Tips go only to the family, never on a public page. People can stay anonymous.
- The family gets a daily summary. It shows new tips, urgent ones first, places mentioned by more than one person, and how much ground was covered. One button downloads everything for the detective.
If someone you love is missing
- Call 911 or your local police now. You don't have to wait 24 hours to report someone missing. Ask for the case number and the detective's name.
- Ask police to confirm the person was entered into NCIC, the national database police use. For anyone under 21, police are required to enter them right away.
- If the person is under 21, call the National Center for Missing & Exploited Children at 1-800-843-5678.
- Register the case on NamUs, the free national missing persons system families can use directly.
- Then ask us to set up a TipTriangle page so your volunteers and community can help in an organized way. Call 567-252-5742.
What we promise
- Free for families. No family pays to search for someone they love.
- Tips stay private. Only approved family members read them. We never post tips publicly.
- No public accusations. We don't name suspects or offer bounties. Rumors spread fast and innocent people get hurt.
- No facial recognition. People compare photos with their own eyes, not software.
- We work alongside police, not around them. Families hand police organized information instead of a flood of messages.
- Data doesn't linger. When a search ends, the page comes down and the data is deleted on a set schedule, unless police or a court require it to be kept.
What we're building next
TipTriangle started with one family's search. We're building it out so any family in the country can use it:
- Daily email summaries for families.
- AI that sorts large volumes of tips, groups repeats, and links every point back to the original tip, with a person reviewing before anything reaches the family.
- A phone and text tip line for people who don't use the web.
- Search tools for missing older adults and people living with dementia, where the first hours matter most.
- Police-ready reports in the format detectives ask for.
Questions
Does it cost families anything?
No. TipTriangle is free for families.
Who sees a tip I send?
Only the family members approved for that search. The family decides what to share with police.
Can I stay anonymous?
Yes. Your name and contact are optional, and we don't store IP addresses with tips. If police or a court lawfully demand records, we can only hand over what we have, which is why we keep so little.
Does this replace the police?
No. Always call 911 if someone is in danger. TipTriangle helps families organize so police get clear, usable information.
What happens when the person is found?
The public page comes down right away. If an adult is found safe and doesn't want to be located, we follow police guidance and never pass along their location.
