Hi, my name is Boris and I've done an two distinct apps and backend software for events industry. One is event mobile/Web app which allows you to create apps for events, add maps, sessions, participants, social capabilities, Q/A sessions, messaging, etc. Other is social media wall app, meant to be used on projectors to display tweets or instagram images on big screens on various events to engage audiences. I would love to show you to them, hopefully you might be looking for something like this. Cheers, Boris.
