Partiful is a free event-planning platform built for the way people actually invite their friends: a link sent over text, a customizable invite page, and effortless RSVP tracking. Founded in 2019 by Palantir alumni Shreya Murthy and Joy Tao, the New York company turned the unglamorous chore of organizing a birthday or a housewarming into something people genuinely enjoy. It became a Gen Z staple, was named Google Play's Best App of 2024, landed on TIME's 2025 list of the 100 Most Influential Companies, and now reaches users in more than 100 countries.
