ThirdPlaces is a humble effort to provide social anchors for curious minds to discover each other, forge meaningful connections, and, more importantly, do crazy things together. And this is how we do it! UR PERSONALITY Let's begin by discovering your unique self, so we can help you discover souls who resonate with your kind of crazy. STARRY NIGHT Now that we know you. Every night, while the world sleeps, we hold space for you to have conversations that reach a star, under the embrace of a twinkling night sky. QUIRKS It's time to bring your eccentric, quirky self in its grand glory. Those obscure thoughts & peculiar tastes find home here, because this place is not for normies ;) VUE Express yourself, not for applause but to find your people. Because that's what has become one of life's rarer gifts. MEETUP Participate in meetups around topics that captivate your heart, and help co-create a space for similar feathers to flock together. GATHERING Now that you've found your flock, let's gather around—Invite other participants to join the gathering, open a room, and explore some craziness together. PICK YOUR FAVOURITES Pick Vues and Meetup participation that truly resonate with you, and we will introduce you to those who match your vibe. START CONVERSATION As you engage with the app, new profiles will reveal themselves. Go explore them and start a conversation with those who pique your curiosity. Accept Connection Travel the slow but meaningful journey from strangers to friendship, one letter at a time. Yes, they do take their sweet time to get delivered. OPEN ROOM Now that you got friends, it's time to engage in some chatter and crazy plans. Simply open or join rooms and watch your social circle take shape right before your eyes. While you are busy doing all that, we keep you safe from unwanted messages from people you didn't sign up for. We encrypt your conversations and chats end-to-end, so that only you and the recipient can read them, not even us. Lastly, we go to great lengths to make sure that the people share a genuine mutual interest before they get to talk. This is how we bring people into your life; it's not supposed to be hard and frustrating. It just has to be honest and accepting.
