1. Zkipster

Zkipster is a service to manage guest check-in on iPads at private events. It launched last year in the United States following a European debut in 2011. Users upload their guest list on a Web platform and then access it at the event through an iPad app; it takes an average time of two seconds to check in a guest at an event with 750 people. Hosts can edit the guest list in real time and send email and text alerts when specific guests arrive. After the event, the system can generate data such as the time that people arrived, which can be helpful when planning staffing for future events. Clients include Hearst, HBO, Hugo Boss, and the Whitney Museum. Future updates will allow each guest to be identified with a photo rather than just a name. Pricing can be done on a per-event basis for $75 or as a subscription for $750 for four months or $2,000 per year.

More than 3,300 die-hard E.D.M. fans attended the nearly three-hour concert—Avicii performed for 80 minutes following an opening set by Henrick B—which generated more than eight million social media interactions. By purchasing a custom designed Aviciit for Denim & Supply T-shirt, guests received a code that they could use to register for the event as well access a private Web site with event info, a message board, Avicii videos and photos, and a platform for social sharing. Customers received their tickets a week before the concert.
