YPlan, which launched for iOS just six months ago, has already been downloaded onto about 10 percent of all iPhones in London. The mobile-only app provides same-day recommendations and ticket purchasing for local events. It will soon launch for New Yorkers and Android.

“We opened a New York office recently. We’re growing the team in New York aggressively. We’re pushing hard to make the app as successful or more successful there as it is in London,” said Rytis Vitkauskas, YPlan’s CEO and co-founder. The company counts 30 staffers at present.

YPlan also announced a $12-million round of funding driven by Boston venture capital firm General Catalyst, which also invested in Airbnb.

The app provides 15 event listings per day with a visual and a short description that’s original to the app, which counts former Time Out employees among its staff. The events are customized for the user based on their social networks and previous activity within the app. Users can buy tickets within the app.

YPlan seeks to bridge an information gap between the $50 billion arts and performance industry that, on average, sells just 60 percent of its seats, and users who are eager to discover interesting and unique things to do.

“Many people have tried before to execute on this idea of last-minute events. They’ve tried and failed,” Vitkauskas said confidently.

After the New York roll-out and the launch of an Android by the end of the summer, the app-makers plan to extend YPlan’s coverage gradually across the U.S. and Europe.
