Vivastream is a social platform that connects people before, during, and after events based on their interests. Users can register on the Vivastream website or mobile apps and fill out their profile. They can then connect with other attendees by searching profiles or viewing their "Who to Know" list of top recommended connections. Attendees are encouraged to share their interests and engage with speakers, exhibitors, and other attendees both during and after events through Vivastream's persistent online network.
