For iPhone · Available on the App Store

Never lose the people who matter.

Cohort keeps your relationships warm. It notices when you've gone quiet, nudges you at the right moment, and drafts the words so you actually send them.

What it does

01

Import your world.

Sync Apple Contacts and Cohort builds your network in minutes. Sort people into sections: investors, founders, family, the ones you'd call at 2 a.m. No spreadsheets, no CRM homework.

02

We notice when you've gone quiet.

Every relationship carries a health score that cools with silence. When someone drifts toward cold, Cohort surfaces them before it gets awkward, not after. You'll never be the friend who vanished.

03

We tell you what to say.

The Concierge drafts the message in your voice: warm, brief, ready to send. Ask it anything, about anyone. It remembers what you talked about last, so you never open with "long time no see."

04

Every relationship gets a rhythm.

Set a cadence for each person: weekly, monthly, quarterly. Cohort keeps the beat, birthdays included, and your streak turns staying in touch into a habit instead of a resolution.

A note from the founder

“Every Cohort user starts with me as their first contact. Message me anytime. I want to hear what you build with this.”
Emiliano Mercenari
Founder, Cohort

Why we built it

You can measure how well your life is going by looking at the people in it.

Cohort exists so you never lose a person who matters, to distance or time. The AI is in service of something older than software: showing up, remembering, being the one who reaches out first. This is not an AI app. It's a life app.
