They say good design is about doing more with less.

Yo is pushing that adage to the limit with a single-purpose app that the founders claim has garnered over 1 million users — 750,000 of them in just a few days of furious viral activity.

This all despite the fact that it does only one thing: send a message saying nothing but “Yo” to your friends. What’s more, the company is about to close a round of financing.

We’re thrilled to announce that the founders of Yo will be joining us at our upcoming MobileBeat event — July 8-9 in San Francisco.

In a session with VentureBeat Editor-in-Chief Dylan Tweney, they’ll be discussing what has lead to the app’s phenomenal growth. They’ll also be answering questions about why there might be more to the simplistic app than anyone realizes.

NOTE: MobileBeat tickets are nearly gone. Grab yours before they sell out!

This session is just one of many at MobileBeat, where top mobile and marketing visionaries will highlight winning strategies for tracking and serving customers along every phase of their journey on mobile.

Other topics we’ll be tackling include personalization, programmatic advertising, seamless payments, customer retention, driving purchases in store, native advertising, targeting across devices, deep linking, mobile analytics tools, predictive apps, the Internet of things, wearables, and more.

Join 1,000 mobile execs, leading brands, analysts, developers, investors, and press for two days packed with high-value discussions, actionable lessons, exclusive announcements, and lots of networking.

We suggest you secure your spot before the holiday, as tickets are very limited. You can register here.
