About

Who’s In? is a simple event planning platform designed to replace chaotic group chats with one streamlined RSVP link. Organizers can create a free event in about 90 seconds and instantly share it via WhatsApp, Instagram, or QR code. Guests tap “I’m In” without needing an account, and attendee lists update in real time. Automatic waitlists handle capacity limits and promote guests seamlessly when spots open. Built-in email reminders reduce no-shows while QR check-in makes door management easy, even offline. For paid events, Stripe integration allows secure ticket collection and automated payouts. With optional Pro features like recurring events, memberships, analytics, and custom branding, Who’s In? scales effortlessly from casual meetups to professional gatherings.
