A dating app, technically Pitch a friend

You know someone worth meeting.

Write why. We'll take it to them. Then introduce them to whoever comes to mind.

THE SHORT VERSION

Greenflag is a dating app built on an old idea: the people who love you are your best introduction. Your friends build your profile and vouch for you in their own words, so nothing on it reads like a sales pitch. And when one of them knows someone you should meet, they make the introduction themselves, with their own name behind it. You decide whether to accept. No swiping, no bio you had to write. And if you would rather look around, you can browse people nearby and get Curious when someone genuinely catches you.

Greenflag is live across San Diego County, California, and it is free: friend-built profiles, introductions, browsing, matching, and messaging, all of it. Nobody pays to be seen.

THE PEOPLE WHO KNOW THEM
HAVE KNOWN IT FOR YEARS
They just never had anywhere to say it, or anyone to say it to.
N°01 · THE TRUTH
NO BIO CAN DO THIS

The best version of you doesn't have a bio.

Your friends have watched the best version of you for years. The one who still shows up at 6am when the surf report was wrong. The one who stops to greet every single dog on the way to dinner, and is always late because of it. They describe that person better than you ever could.

N°02 · THE IDEA

On Greenflag, your friends build your profile and introduce you to people they trust.

Their words. Their stories. Their photos of you mid-paddle, mid-laugh, mid-life. You can't edit what they say. And when one of them knows someone for you, they send your profile over themselves, in their own thread.

“will drive out to Sunset Cliffs for twenty minutes of sky. every time. even midweek.”

N°03 · WHY IT WORKS

A stranger's bio is marketing. A friend's word is a promise.

N°04 · SAN DIEGO FIRST
LIVE IN SAN DIEGO · ONE INTRODUCTION AT A TIME

Starting small.
On purpose.

Greenflag opens in San Diego, one city at a time. We think real connection happens face to face, so your friends make the introductions and you meet close to home. Same coffee shops, same beaches, same Tuesday nights. That's how something lasts.
