About 9ONE0

Who makes 9ONE0.

9ONE0 is a safety intelligence platform and private dating journal built for women.

Run a 9ONE0 Check on a phone number before you meet someone, and keep private notes on everyone you date in The Vault. The name means being one step ahead of 911. 9ONE0 is made by Mintploy, Inc. in Los Angeles.

Why 9ONE0 exists

In the founder’s own words:

“I grew up in a family of detectives. My father, both of my grandfathers and my uncle all investigated serious crimes. At our dinner table, you looked things up before you trusted the story.

9ONE0 gives you that same habit before a first date.”

Kaori Tempel, founder

What 9ONE0 is and isn’t

9ONE0 is a personal safety research tool and journal. A 9ONE0 Check starts from a phone number and shows what public and licensed records say, so you can see where the record and their story might differ. The Vault is free: a card for every person you’re getting to know, with your notes and flags.

9ONE0 is not a consumer reporting agency under the FCRA. You can’t use it for hiring, renting, lending or insurance decisions. Public records can be incomplete or out of date, so look any record up yourself before you act on it.

See what a report covers, and what it doesn’t, and read our FCRA notice.
