Every step between a match and a first date

Dating apps stop at the match. Who he really is and how to meet safely is still on her. 9ONE0 is safety intelligence that gives women more confidence to say yes to a first date. • Phone check: run his number, see what the public records show in seconds • Self-check: she requests, he shares his own report • The Vault: a private encrypted journal to log dates and spot patterns • Date booking: he offers times and venues at partner restaurants, sends ride credits. Her home address stays private








Hi Product Hunt, I'm Kaori, founder of 9ONE0.
I come from a family of detectives. My father, both of my grandfathers and my uncle all investigated serious crimes in Japan. I grew up checking facts before trusting a story.
For years, my girlfriends sent me a name, sometimes just a phone number, before a first date. Often a phone number was all I needed. I built 9ONE0 so every woman can arrive at every date with that same clarity.
Online is now the No. 1 way US couples meet. 57% of US women say dating apps aren't a safe way to meet people.
What's live today:

Safety check requests. Free to ask. He runs a check on himself, sees it first and shares a Trust Card. Criminal, sex offender, eviction and federal lawsuit results are always shared.
The Vault. A free, encrypted dating journal. Log dates, tap green and red flags, see your patterns and reach your safety contact in one tap.
Checks start only from a number you were given. No name, email or address search. A check is $25. The Vault is free. Covering 45 states today, California opens January 1, 2027.
Do you know anyone dating that could benefit from this?
