Mozi: A place for your people Your people are scattered. Some live in your city, some are an ocean away. Some you saw this month, others it’s been a year. You find out a close friend was in town a few days after they left. You have a free evening but don’t know who’s around to do something fun with. You’d love to take a break from social media, but it’s a thread tying you loosely to people you love. Losing touch with people you care about isn’t a failure. It’s a hallmark of adulthood. Mozi is the app our friendships deserve: a way to stay close even when we’re busy and spread out. How Mozi works Add your trips, shows, and the events you’re going to, it takes a few seconds. Mozi turns them into one picture of where you’ll be and when, so your people know where to find you. Share any plan with anyone, even friends who aren’t on Mozi yet. See what city your people are in now and where they’re headed next. When your paths are about to cross, Mozi tells you, before you miss each other, not after. Private by default Mozi is social, without the media. No brands, no public feeds, no follower counts, no ads. Connections are two-way (friend model, not follower model), and your location is only ever shared at city level, with people you choose. The more of your people on Mozi, the better it gets. But you only need three or four friends you can’t wait to see when your lives overlap next. Add more as you go. Mozi also holds the little things that keep friendships warm: birthdays, kids’ and pets’ names, notes on what they mentioned last time, and shared photos from the times you were together. We're a a small, remote team building Mozi from Seattle, San Francisco, New York City, Medellin, Vienna, Madrid and Dubai. Find us at community@mozi.app or @getmozi on Instagram and Twitter. We'd love to hear from you.
