Meetup is an online platform that connects people with shared interests and facilitates the organization of local events and group activities. Launched in 2002, it allows users to find and join groups based on a wide range of topics, such as hobbies, professional interests, or social causes. Users can attend events, network with like-minded individuals, and even create and manage their own groups. The platform aims to help people build communities and foster in-person gatherings, enhancing both personal and professional connections.
