This app may get friends to your party better than you can

Sometimes getting people to respond to an invitation is hard. Maybe they’re lazy, maybe they didn’t get your text, or maybe you sent your invitation right before the event was going to begin. iSocialite hopes to fix that.

The startup wants to help you get friends to your events without having to call, email, or text them. The app, which debuted in the iOS App Store yesterday, acts basically like a calendar. You and your friends upload events you’d like some social interaction on into the app. Friends who have RSVPed show on the event’s page. And you can push those events out to Facebook and Twitter and can sync with your calendar should your regular morning run turn into a rager.

On stage at the DEMO conference in Santa Clara, Calif., the company used the app to set up a happy hour for the attendees in a matter of minutes. “With two clicks, you’re in the social mix,” said the company’s founders.

“Clearly events need to be mobile,” said Josh Elman from Greylock Partners when offering feedback during the sage panel. He asked, “This seemed very easy to use. But how do you stand out from the noise?” Mike Cassidy of Google was also impressed by the app’s simple user interface, but said that this company will need to reach critical mass to succeed.

iSocialite provides all the information you might want for an event as well, including the date, time, location, organizer’s name, and even how far the event is from you. Each event gets its own icon as well, indicating the type of activity involved, such as “cheers,” which indicates that there will be drinking at the party.

The three-person startup has its sights set on renting office space in SOMA (South of Market Street) in San Francisco. Currently DreamWare, the creator of iSocialite, is based in Los Angeles.
